actiontec wireless

[#1]

Recently my xbox couldn't detect my router anymore and through many tests I concluded that the signal was somehow now too weak. Do you think that this guide http://www.dslreports.com/faq/12506 would help me improve my wireless signal if I use the secondary router for wireless?

Yes, an extra wireless router can help if you're not getting good coverage throughout your house.

Before adding a Wireless Access Point (WAP), you might try changing the wireless channel.  It could be that there is now some interference on the current wireless channel.

so my actiontec will not be set to wireless and i'll have my belkin set to wireless

i have already tried switching the channels
