For about that last week, the signal from my airport express to my G5 desktop keeps degrading. It won't hold 4 bars,even though it is in the same room as my G5. It will go down to 1 bar. IfI turn airport off and then on again, I get full signal for a few moments, then it degrades again. What's weird is that my iBook and my sister's iBook, which are rooms away, get full strength.

I've tried restating the airport but it hasn't fixed ythings, Right now I have one tiny little bar and I will have to turn airport off and on to get enough signal to post this.

Can anyone tell me what's happening and how to fix it.
