Regarding your concern, placing a computer right next to the router is not a very good idea. Why? because it is a source of EMI (Electro-Magetic Interference), which causes:
>Inability to connect
>Undetected wireless signal
>and very poor wireless signal
Not only that, the equipments below are sources of EMI's
>Computer sitting on metal surfaces
>Computer sitting on carpeted floors
Here's a suggestion:
>Place the computer at least 6ft
away from the router
>Make sure that there are no equipments mentioned above, within 3ft near the router
>Open a browser (Internet Explorer, Mozilla Firefox, Safari, Google Chrome, or Ubuntu) anything will do.
>Then access your router's page by typing 192.168.1.1
on the address bar of your browser and hit Enter.
>Logon to your router by leaving the Username blank and in the Password box just type "admin
" (without the quotation marks " " )
>Click on the Channels and SSID
link under Wireless
. (as shown below)
>The only thing you can play with wil be the channels.
>There only are 3 Clear Channels that you need to choose from. Channel 1, 6, and 11
>Switch channels between those 3 mentioned above and check which channel has the Excellent signal and save the settings by clicking Save
