signal strength

[Dollar]

Recently my wireless network has been acting up. The signal strength will keep jumping good to bad and bad to good and its really slowly annoying. It did not happened before nor does it have any distance factor concern as the wireless connection to the router is just a metre away.
Is it possible for a wireless adapter to go bad?
It was working very fine when now it gets unstable signal strength.

Do you live in a congested area where perhaps someone else setup and started using a wireless router. If so they might have theirs on the same or maybe one channel away from yours which would definately cause sporadic problems. So if this is the case i'd suggest trying to switch the channel first and see if that doesn't fix you up.
