I have a Linksys WRT54G Router, I've had it for about 8 months, have been using the wireless on it for about 3 or 4 months. Up until this weekend I'd have anywhere from 70-100% signal strength. The laptop is about 30 feet away from the router and the signal goes through 1 wall. This weekend I notice I'm consistently below 50% signal strength. Nothing has changed as far as location. So today I move the router a bit closer, now probably 20 feet away and still through 1 wall, and the problem still exists. I drop down to 20% signal strenth pretty often. Is something going wrong with the router, or is this an issue with the NIC in the laptop? The laptop is a Powerbook with built in Airport card. Additional info: I just walked into the room with the router with the laptop and held it right up to the router. Still didn't get signal above 50%.
