Wireless B vs G vs N vs AC | What’s the major difference

Wireless B vs G vs N vs AC | What’s the major difference?

linksys-g-wireless
From the stone age, but still running strong this is a wireless router that can do both wireless B, and G modes.

Wireless standards keep evolving, and with each major evolution they get faster. So today we will look at the wireless standard itself, and review the differences in the difference modes and their speeds.

WLAN Standard 802.11

ieee-wireless

The Institute of Electrical and Electronics Engineers (IEEE) is an organized group of engineers. They created the standard for WiFi technology which all wireless routers will follow. They called this standard 802.11. All routers at the time were built around this standard. There was no letter designation, such as “G”, “N” or “AC”. This 802.11 standard was released in 1997.

The main problem with this standard was that it was way too slow. Today’s routers are made to this standard and thus the letter designations come into play.

802.11 Enhancements

Lets explain a few things first. We will be starting off by talking about Wireless B, but something did come before B and that was the A standard. A was released about the same time as B, but B was cheaper thus being more popular. A devices were mainly used by businesses so you don’t really hear about it when looking for routers online (and you won’t). Wikipedia has some great information on the history of wireless standards.

802.11B – Wireless B

Routers that came with just Wireless B are not longer made though a bunch of routers still support Wireless B so you should know a little bit about it. Wireless B can support a maximum throughput rate of 11mbps. You can also use the signal with no interference up to 150 feet away. Wireless B operates on an unregulated 2.4GHz range which is bad because many home appliances operate on this frequency.

This means that home phones, and things like microwaves can actually cause interference if your router is somewhat close to these devices however if it is not too close you should be good.

It is also good to note that Wireless B can actually be regulated on Wireless G routers that allows channel selection, and supported Wireless B.

802.11G – Wireless G

The G standard was a big push forward, and supports up to 54mbps. Wireless G just like Wireless B initially was unregulated until manufacturers like Cisco’s Linksys routers started adding channel selection support thus allowing you to switch channels and reduce interference.

Wireless G is backwards compatible with Wireless B so many routers support accepting both signals at the same time. Though I am about 100% positive that none of you reading this actually have a device that only supports Wireless B, but more likely devices that run on G or N. G’s main benefit is that it is faster than Wireless B.

802.11N – Wireless N

Wireless N supports a max speed of up to 300mbps with two antennas. With an additional antenna it can reach speeds up to 450mbps, Normally though you can expect to see speeds around 130mbps or so.

Wireless N operates on 2.4GHz and 5.0GHz bands at the same time. N devices can operate on multiple signals. It is called MIMO (Multiple-IN – Multiple-OUT). That combined with the two to three antennas, increased signal power, and rage it is clear Wireless N is a standard you want to use for very high speed devices.

 802.11AC

This is the next big thing as of the writing of this post. Wireless AC is out, and on the market offering speeds up to 1733mbps which is an enormous increase from Wireless N. It is also know as “5G Wi-Fi”. The standard was introduced in 2012, which is now the current standard that can be found on many newer routers. AC Routers also support Wireless N which makes them fully backwards compatible with G.

I hope this post was very informative, and helps you make a decision on what type of router you want to buy. Honestly anything from G and above suites the needs of most people unless you, and your whole family are all doing some very bandwidth intensive tasks.

If your interested in buying a new router consider an AC router. Here is a link below to an Amazon search result for AC routers.

Comcast Modem’s & DDNS

Comcast Modem’s & DDNS

ddns

Okay so my Comcast modem gave me such trouble with DDNS that I figured I’d write a post about it.

What I was trying to do

I was trying to set up an IP camera with a hostname address from No-IP so I could view it from outside my network. The problem is my Comcast modem had no default DDNS support, and when I did visit my IP it would not open the appropriate ports even though they were forwarded. It took awhile but I did find a permanent and correct solution.

What I did to get DDNS working

You need your OWN router for this to work.

So what I ended up doing was putting my Comcast modem into bridge mode you can do this by logging into your Comcast modem by putting http://10.0.0.1/ into your browser’s address bar.

Once you are logged in you should see something similar except the only difference is instead of Enabled your’s should be Disabled.

Note that you will need your own router because what bridge mode does is pretty much turn off the router part of your modem, and make it just a “modem” in the traditional sense which is what we want.

bridge-mode ddnsAfter you do this assuming everything went smooth you can now plug up, and turn on your router so that it can start routing your internet to the various devices you own.

Now go to Google, and type what is my IP. It should be different than the regular IP you are usually assigned with just your Comcast modem. If so everything is a success and you can now use your own router to perform all household networking functions, and your Comcast modem will be just that a modem. Not a “2-wire” or a modem-router or nothing like that just a modem.

Troubleshooting

If things are not going as expected here are some things you can try that I know will resolve your issues.

Turn OFF your:

  • Modem
  • Router
  • PC

Than turn on your Modem and wait 30 seconds.

Than turn on your Router and wait 30 seconds.

Than turn on your PC and you should have internet.

You will know your Comcast modem is in bridge mode because it will say it is so in the web interface. Also the lights on the modem box will be different. The top 3 will be solid, and the two telephone lights will be flashing. If all else fails just disable bridge mode, and try again. It can be wonky sometimes so have patience its not broke (trust me).

I hope this post helped some of you guys!

How to check if your own network port is working (NIC)

How to check if your own network port is working (NIC)

network card

If you have ever wanted to check your own NIC (Network Interface Card) to see if it working than you have come to the right place!

Checking Your NIC Steps (CMD) – Windows

I only use and have a Windows machine so we will be using Command Prompt. So hit the key on your Keyboard located on the bottom left hand side that has the Windows logo on it.

Afterwards type CMD into the search, and hit enter to open Command Prompt.

start-menuAfter Command Prompt is open you can check your Network Interface Card using type different commands.

The first command you can type is:

ping 127.0.0.1

cmd-ping1

or

ping localhost

cmd-ping2

If you have ever dealt with networking or running your own website I’m sure your already aware of the term localhost.

If you get a response at all than your computer’s network port is working.

If your still having trouble connecting to the internet, your router, or any other device via an Ethernet cord than you should troubleshoot those devices, and cables since you have just determined that your NIC (Network Interface Card) on your current device is in fact working.

If you DO NOT get a response using one or both of the above commands than the Network Interface Card on your machine is BAD. If you just got your computer, and it is custom built by yourself than you should double check that you have installed all the necessary drivers. Windows Update in fact is NOT a fix all solution for hardware and does not have drivers for everything.

If you simply don’t have a CD drive to put the driver CD that came with your computer or motherboard than usually you can get the drivers online from the manufacturer’s website.

In a later post I’ll go over the use of Wireshark to help further troubleshoot an entire network to help track down and identify network issues.

Come back to http://www.prenticenetwork.com/ and search for the “Wireshark” to find the article mentioned above.

How to use FileZilla

How to use FileZilla

filezilla

FileZilla is a free FTP (File Transfer Protocol) client. FTP is a method for download or uploading files to a server. FTP works in a few different ways, and has unsecure, and secure protocols within.

Today though were just going to mainly show you how to use FileZilla so you can upload some files to your server. We will be demonstrating using the dedicated server this site is hosted on.

This guide also assumes you have FileZilla installed. If you don’t than you can download it here: Download FileZilla. It is pretty self explanatory on how to install it.

How to use FileZilla

1) Locate Site Manager

First thing you will want to do is simply add your site! Before you can do that though you will need to open up the site manager. It is located in the upper left hand corner. If your having trouble just refer to the below picture.

filezilla-screenshot

2) Add Your Site!

Now I’ve grayed a few things out, but I’ll explain it all! When you open the site manager you will see what you see below. You will want to click “New Site” and a new one will populate the list on the left. Name your site so that you can identify it later. The settings on the right side are the settings associated with the currently highlighted site on list located on the left hand side.

The settings are pretty easy. Host is simply ftp.yoursitename.com really that is all there is to it. Than for Logon Type you will want to make sure it says normal (it says Anonymous by default). After that enter your cPanel username and your cPanel password. If all is well hit connect!

site-managerIf you happen to get any errors it will most likely be because of an incorrectly typed username or password. Double check your spelling on how you typed your site into the host section as well.

Connecting to a server via SFTP – SSH

Follow the same procedures except on the host slot you will need to put the server IP address. The Protocol should be SFTP, and Logon Type should be normal. Once you try connecting it will ask you to trust the credentials. Hit yes, and your into your server directly using FileZilla.

The best way to clean your monitor

The best way to clean your monitor

clean-monitor

So many people including myself have long wondered, and asked the question what is the best way to clean a monitor? No real answer have ever truly dazzled me or likely yourself.

Most people just opt to get something like the Zeiss cleaning wipes which are inexpensive small wipes for screen, lens, and the store.

I discovered that one of the best ways to clean a monitor is with toilet paper, and water. Your probably pretty confused, but it’s true this is what I have found to work the best.

Toilet paper actually should be an obvious choice if you think about it. It is non-abrasive, and pretty absorbent. Toilet paper is soft, and not meant to hurt you let alone your screen. It might leave behind a few specks of dust from the paper which can easily be removed, but for the price of this cleaning option who would complain about something as simple as that.

Now this is not all I use. I have given in and bought those packs of Zeiss wipes from Wal-Mart. They work exceptionally well, are non-abrasive, and leave nothing behind. I find myself usually having to use between 3 and six wipes to clean a full size 22 inch monitor that has collected a fair amount of dust, with some hand prints, and some liquid specks from water, soda, or anything.

After I finish with the wipes I might go over it all with a small amount of toilet paper, and i’ll end up with a nice squeaky clean monitor.

You can also use the methods I just described to clean other things too like your smartphone, glasses, tablet, and just about anything else with a screen.

I hope you guys enjoyed this article, and as always check back at https://md5live.com/ for more news, articles, posts, and updates.

How to use f.lux

How to use f.lux

f.lux

Download f.lux for free.

The program f.lux is suppose to reduce eye strain by changing the brightness and color of your monitor. If your curious as to why you would want to use this program the reason is that we are not meant to see the sun after it sets. LCD’s and other types of monitors with their bright white light simulate the sun making it difficult for you to sleep after using your computer at night.

This is where f.lux shines and helps you rest better. It is suppose to pretty much simulate fire or natural light. A candle is not the sun, and your body knows this so what f.lux can do it simulate candle light being emitted from your monitor helping you sleep after your done using it.

f.lux has many options for night lighting, I’ll list them here.

  • 1200k: Ember
  • 1900k: Candle
  • 2300k: Dim Incandescent
  • 2700k: Incandescent
  • 3400k: Halogen
  • 4200k: Fluorescent
  • 5000k: Sunlight

As you can see f.lux has many light modes. It also has Darkroom mode, and Movie mode. My personal favorite night-time lighting option is Incandescent. It is not too yellow, and is not too bright either. Ember makes everything pretty much yellow and if you need to identify color you won’t want this option.

I would only recommend going as low as Dim Incandescent anything lower, makes it hard to identify colors properly though the eye strain reduction is pretty nice.

The program also is able to go into Safe Mode which as far as I can tell just removes the background transparency.

There is an extra’s button which lets f.lux take control of Philips hue lights which is an amazing feature! I don’t have a Philips monitor or lighting system, but I’m sure it is incredible.

So all in all get f.lux it is free, and helps you sleep better by reducing night-time eye strain.

RGB vs CMYK

RGB vs CMYK

If your unsure of which to use than your in the right place.

RGB vs CMYK
Image taken from: kb.mcad,edu

 

RGB – Red, Green, Blue

RGB is an additive coloring method. These three colors can form any color in existence, but the problem is that ink cartridges do not come in RGB.

RBG is the color scheme that is associated with electronic displays such as CRT, and LCD monitors, digital cameras, and scanners.

RGB is an additive type of color scheme. It combines all three primary colors together (red, green, and blue) in various degrees to create a variety of different colors. For example white is when all three colors are combined together. When they are applied together at the lowest degree possible you get black.

Many photo editing software’s use RGB because it offers the widest range of colors to choose from. This is why you never see CMYK used in digital applications that are not designed to ever touch paper.

Pro tip: Photoshop (Raster Graphics) – Defaults to RGB

Pro tip: To avoid any discoloration when printing something make sure to convert the color mode of your image to CMYK before printing. If it is for something simple though usually the computer can handle the conversion and print what you see on screen just fine.

CMYK – Cyan, Magneta, Yellow, Black

CMYK is a subtractive coloring method. Printers print in CMYK mode even if the image your printing is in RGB. CMYK is a four color mode that uses the colors of cyan, magneta, yellow, and black together in all different degrees to create the desired colors.

It is a subtractive process, which means that each additional unique color means more light is removed, or absorbed, to create colors.

When the first three colors are added together you do not get black, but actually a very dark brown. The fourth color black is used to completely remove light from the printed picture so you perceive that area as black.

Pro tip: Adobe Illustrator (Vector Graphics) – Defaults to CMYK

AMD’s APUs.

AMD’s APUs.

AMD APU
Image taken from: http://eecatalog.com/

AMD APU’s are the latest greatest thing from AMD. They are as seen in the above image a hybrid of a CPU and a GPU. This has many benefits, and a few drawbacks. This really is a great innovation, but more so for laptops, and tablets not really desktop computers. An APU can work with an AMD Graphics card if one is installed on the same machine, and together can help each other make your applications, and games run smoother.

However once you get more into the enthusiast area where you want to start using high end cards like the AMD 290, 290X, or 295X2 than things change. At this point you would be better off having a dedicated CPU, and a dedicated GPU. If you turned on the options that allow the APU to work with your GPU and your GPU just so happens to be a high end card like the few we listed than your APU will be a major bottleneck to your performance.

Currently one of the best processors you can get from AMD that will get you tons of performance is the FX-8350 (Not an affiliate link). It is a fast eight core processor that runs at 4.0Ghz with some variation in different models.

AMD – Radeon products are known to run hotter, and use more power than Intel – Nvidia products, but you get what you pay for. AMD – Radeon products usually cost between 20%-50% less than the competition. Note that this is only an evaluation of consumer grade processors and graphics cards not commercial grade or server grade.

If you are going to settle for an APU go with the A10-7850K.

amd-apuOtherwise if your going with a dedicated CPU – GPU build than choose this processor.

amd-cpuBoth chooses are good considering they are pretty much top tier consumer grade products which by all standards are cheap as far as price is concerned, and high as far as quality is concerned. You really can’t go wrong with either one. I myself have a FX8350 with a after-market CPU cooler and I could not be happier.

My brother has an AMD A10-7850K with a stock cooler, and could not be happier though his processor with the stock cooler does run a little hot but nothing to the point that is concerning. At 100% full load the APU did reach higher temperatures than my FX8350.

So again in conclusion they are both good options, but personally I would go with the FX8350. For more news, updates, posts, and reviews check back here at https://md5live.com/

How to view hidden files, folders, and display extensions

How to view hidden files, folders, and display extensions

hidden files

This is actually a lot easier than you might think. Their are a lot of reasons to enable these options and view these hidden files, folders, and extensions. If you work with CODE or graphics often times you might find yourself changing extensions or looking for something you can’t find. Starting below we have a step by step guide on how to do these things.

View Hidden Files, Folders, and Extensions:

Step 1 go to control panel by clicking the start menu icon than clicking “Control Panel”. After that you will than click “Appearance and Personalization”.

control-panelStep 2 click folder options

folder-optionsStep 3 click the view tab

view-tab

Step 4 (This does not require a picture)

As you see on the above picture you can click “Show hidden files, and folders, and drives”. Once you click on that you can view all those hidden files, and folders on your computer.

View Extensions:

To view extensions you just have to uncheck “Hide extensions for know file types” as seen in the above picture. Once all these tasks are complete than you have completed your missions, and can move on to better things.

I hope this guide helped you guys, and as always check back here at http://www.dlprentice.com/ for more stories, reviews, tips, tricks, and more!

 

Computer Building Guide Tips

Computer Building Guide Tips

This will help you understand a computer so you can build one.

Video at bottom of guide.

First off http://www.newegg.com/ is like the best site (not amazon) for finding PC components to build a computer. Amazon is pretty good for ordering the components, but if your to look something up just use newegg their the best they are also nice to order from.

With this list of tips we & I think that you will most certainly have a higher chance of success, and won’t get the wrong parts to go with one another, and won’t miss anything at that!

1st! Have a budget!

When deciding on a budget you need to decide first how much can you realistically spend. $200~$400 for a run of the mill internet and streaming PC is about standard. $500~$1000 will get you a low-budget to medium budget gaming, media, and entertainment PC, and $1100~$6000 will get you a high end computer that can do everything including play the latest games for years to come. This is from a desktop ONLY reference.

A note on the budget this assumes that you are going from nothing to a whole computer. If you have an existing computer upgrades are easy, and can be found at this article LINK instead.

2nd! Decide on a brand

By “brand” we mean Intel or AMD. Intel & AMD make CPUs (Central Processing Units), which are the brains of a computer. Determine the “brain” will determine other components the computer will comprise of. Their a few key differences I’ll outline below

AMD

  • Cheaper
  • More “Bang for your buck.”
  • Generally more cores
  • APU Technology
  • “Mantel”
  • Good track record

Intel

  • Pricey
  • Generally out preforms AMD
  • Very efficient
  • Excellent track record
  • Highly efficient hyper-threading
  • Less Cores

So as you can see AMD is more for the PC builder wanting to watch their budget but still receive excellent performance. Intel is more for the enthusiast looking for maximum performance, and efficiency. I myself have a computer comprised of an AMD processor with the associated motherboard, and GPU (Graphics Processing Unit). All together (with an eBay deal I snagged) cost me around $1000~$1200 total. My computer can play all games with ease, and can perform excellently though an Intel i7 processor could probably outperform me even if only marginally.

APU Technology on the AMD side means that the CPU can handle operations that normally a graphics card would do. Mantel is AMD’s version of DirectX.

3rd! Know what makes a computer “work”

Okay so after deciding on a brand of processor you’l want you need to understand all of the components that will go together to make your final piece – a functioning computer. Below I’ll list everything you need to make a computer work.

  • Computer Case
  • Motherboard
  • CPU – Central Processing Unit
  • RAM – Random Access Memory
  • HDD – Hard Disk Drive
    • SSD – Solid State Drive (For Operating System)
  • PSU – Power Supply Unity
  • CD/DVD ROM Drive – For CDs/DVDs
  • Graphics Card

Now I’ll cover this list in more detail so you understand. The computer case is what will house everything and will generally cost around $20~$100 depending on the brand. The motherboard runs about the same as the case. The thing to considering with the motherboard is the socket type. For example my motherboard takes an AMD Processor. The AMD Socket it accepts are AM3, and AM3+. You don’t have to understand what that means just understand when looking for a processor that it needs to have the correct socket type in order to be used with your motherboard. So if the CPU your looking at says FM2+ it WILL NOT fit a motherboard that say it only accepts AM3/AM3+. Some motherboards are more versatile than others and will accept more socket types than others so be aware of this.

Don’t forget to get thermal paste with your CPU. Generally though your CPU will likely come with some already pre-applied, or if you get an aftermarket heatsink it will come with some as well. The best thermal paste is “Artic Silver”.

Intel & AMD CPU’s are not interchangeable, they won’t even fit eachother because again different sockets won’t fit eachother. If you somehow managed to get a different CPU forced into a wrong socket well you probably just broke your CPU and motherboard. So take things slow, and review your components specifications sheets always!

RAM is pretty easy to get, use, and install. All you need to know is the socket type that the motherboard takes for the RAM other than that it does not matter the company or brand. So if it says DDR3 than you can only use DDR3 RAM you can’t go backwards and you can’t go forward. Within DDR3 RAM you will likely incounter different speeds, and sizes. Just go with 2 medium cost 4 Gigabyte RAM sticks.

HDD stands for hard-disk drive, and is where all your information will be stored. Just make sure you get the right size at the right speed and your set. You could also consider an SSD to use as your main Windows Boot Drive, which won’t be covered in this guide.

PSU is your power supply. When your looking for one just make sure it gets at least 80% efficiency or is rated at least Bronze80. Otherwise generally 750~1000 Watts is good if building more on the high end. On the lower end 500 Watts should work.

You will likely want a CD/DVD drive for obvious reasons we won’t cover just get a cheap one in case you use or need to use a CD/DVD.

The graphics cards will determine how well your computer can render 3D and 2D images, and graphics. If your going for a cheap computer just about any card should work fine. If your going for a more high end computer you’l appropriately need a better graphics card. Also generally AMD is paired with RADEON Graphics Cards, and Intel is paired with Nvidia Graphics cards. Below is a list of their best cards currently at the time of writing this.

  • AMD/RADEON – 290X2 ($1000+)
  • Intel/Nvidia – GTX Titan ($1000+)

Well that about sums everything up. While this guide is full of tips, and information it does not include pictures. Though you should have a solid understanding now before making any purchases. Below is a video created by someone else other than us that shows how to assemble a computer after you have gotten your components.
