Download and install NetStumbler, best to run when your neighbours are using their wireless routers. The best channel to choose for your wi-fi network would be the one that's not used by any other network and that gives you the best SNR. Choosing the best channel may not improve transfer speeds, but will give you a better wi-fi connection and less connection drops.
If the next day you find the signal drops or it starts disconnecting, that usually shows that another neighbouring wi-fi network popped up and you'll need to redo the process and find another channel. Only hope is that your neighbours are normal folks and they don't start switching channels as well :-) Some routers have an option to choose a clear channel, you could try that (on my 3Com wi-fi router the channel drop-down has a "Clear Channel Select" option).
ASUS R2H: Don't set the router to channels 12 and above as the R2H driver doesn't support those, even if you are living in Europe. Usually there is a driver property that sets the region (certain channels are allowed in certain regions, see here for details), but not on R2H.

Update March 1st, 2009:
As NetStumbler may not work on Vista you can use Vistumbler or inSSIder to track signal strength.

Hi Omar, my first reader from Iraq, welcome! :-) oh I see you sent me an email as well, I'll do my best in replying over there then.
nice article. I actually just tried the program. It doesn't seem to work with my wifi card. "No wireless adapter found" or something like that is all it says at the bottom and it finds nothing. Any suggestions? I have vista and ubuntu. I can have windows 7 instead of vista if needed.
Hi Kate,
See if you can use the two new tools I added to the post, Vistumbler or inSSIder to track the signal strengh when you are trying out channels.
For Ubuntu people seem to use Kismet, airsnort, aircrack-ng.
HTH,
Dan
You're awesome! I got Vistumbler and it's working perfectly ^.^
Glad it helped, Kate :-)
