WRT400N Upload and Download Speeds

Question

I have a WRT400N router. I have a network set up where I am physically connected to the router while my two room mates have a wireless connection. When I test my connection I have a download speed of 25 Mb/s and an upload of about 2 Mb/s. My room mates however have a download speed of .5 Mb/s and upload of about .5 Mb/s. They are getting full signal strength from my router, so I am not sure what the problem is. What is the problem and how do I fix this? They should be getting much faster upload and download speeds.

After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch.  If you have not done this since the last firmware upgrade, then please do this now and see if it corrects your problem.  If you saved a router configuration file, DO NOT use it  ---  you must setup the router from scratch.
If the above does not correct your problem, then the most likely cause is simply a poor wireless connection.  This can occur even if your computer shows "5 bars" or "full signal strength".
There are many causes for poor wireless connections, and many solutions:
First of all, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
If your problem is that you are getting poor speed between your wireless n router and wireless n adapter, in the router, make sure the "Radio Band" is set to "Wide".
Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.
In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4. For wireless n, make sure your standard and wide bands are at least 2 channels apart. For example try standard band on channel 11, and wide band channel 9.
Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna, if external, should be vertical.
Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. If your current network is not listed, enter its info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".
If the above does not fix your problem, download and install the latest driver for your computer's wireless adapter.
Some users have reported improved wireless performance by switching to WPA encryption.
If you continue to have problems, try the following:
For wireless n routers, try setting the "n Transmission Rate" to 162 Mbps, and the (wireless g) "Transmission Rate" to 54 Mbps.
If you still have trouble, download and install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.
Hope this helps.
