ATV keeps losing wireless connectivity

My ATV keeps losing wireless connectivity and it's really starting to piss me off. I wanted to hard wire the thing but the solution that I proposed people said it would not work. So is there anything at all that I can do to make it stay on. I have a AEBS only one room away and I live in an apartment on the end on the top floor. When it was in the living room hardwired it was never an issue but when I moved it closer in the bedroom but wireless it loses the connection everyday almost now. But the signal strength is maxed out. Please help if you can.

One solution I just thought of!

Well one thing I have not tried and I am going to today now that I thought of it is use Netstumbler to find what channels the other wireless networks around me are at so I can put mine on a different channel.
