I'm having an odd problem and I can't seem to find any solutions for it online. I have a WRT150N with the latest official firmware. It runs fine, but over several hours the signal quality slowly degrades. When I first connect from the next room, I get a connection of about 50 to 60%. 24 hours later, the connection is down to about 15 or 20%. If I power cycle, I go back up to the initial connection quality. What's going on here? Is there a way to fix this so I don't have to power cycle once or twice a day? Thanks!
