What can you do to make your internet access faster ?.
You start your computer, you open your browser and connect to your favorite web site, and wait, and wait, and after some time the page actually starts to load. Whoa! What is going on?
Your internet bandwidth is to low or it is in need of optimization.?
So how do you go about optimizing your network connection speed (bandwidth)?
Well there are some things you can do but first there are some things you need to know about networking, some acronyms and jargon (geek / nerd stuff) that need to be explained.
Now lets see what we can do to speed up your connect speed and get that page to download faster.
Network connection speed optimization comes in two parts, your network card in your computer and your router if you have one.
Network connection speed for your network interface card (NIC) you need to know what the speed and duplex are set for. To find them you got to My Network Places, right click and select properties.
Network connection speed for the router you can go in to the settings (if this is a home router) and check the 'link speed/duplex' it should be 100/full. (There may not be a setting in any options on newer routers).
The other thing you can do in the router settings is set the MTU, the optimum setting should be 1500 for the MTU although it could be higher or lower depending on your network connection to your ISP. You can run a test with this program - Use the TCPOptimizer to check you network connection speed.
Note: The TCPOptimizer program will work from behind a firewall but not with a proxy server. If you have Windows Firewall Service you could disable the service while running the tests, just don't open your browser or connect to anywhere while testing.
If you are behind a corporate firewall or have a home router with firewall turned on use the router settings to do your testing. Use the 'Gateway' IP for the test. If your network uses a proxy server to go through the firewall then you can only test settings on your side of the proxy server, again use the 'Gateway' IP address to do your tests. The program will error out but the test will see the MTU for your NIC.
If you are connected directly to a Cable/DSL modem you can not modify the settings, nor can you see the speed/duplex setting. If you find with your testing that the MTU is wrong you will have to contact your service provider to get the modem settings changed or a new modem.
By changing the MTU and the TCP Receive Window you will see a boost in speed. As I pointed out in the definitions section modifying the TCP Receive Window may cause more problems. Do not modify this setting unless it is the last thing you can do to stop the dropped packets causing the connection to appear to be slow.
The only thing left that will speed up your connection is the 'Bandwidth' that your are getting from your ISP. Bandwidth is calculated in BPS - Bits Per Second.
If you are on dial up the maximum you can send/receive is 56,000 (56K) Bit Per Second.
If you are on Cable or DSL then the game changes, you can get from 64 KBPS up to 20 Giga Bits Per Second (above 10 GBPS range is very expensive and normally only large corporations have this type of connection) for the home user or small business the speed will be in the range of 128 KBPS to 10 GBPS (these are US specifications only other countries will be different).
You can use these network connection speed terms to baffle your friends and talk to geeks, however your friends may call you a geek... :)
