Possibly changing the wireless broadcasting channel might make a difference?
Link. Try channel 9. If still no good have a play with other channels.
If you can log on to the huwei router then copy down all the settings for AOL.
You'll still need all the info to set up the belkin so find out the settings via AOLs help page, or the router you have, and set it up manually. If the router has an "auto" tab for broadcasting then select this first.
