Hi, i'm not really that experienced when it comes to technical things on a pc. I have looked on the net about increasing signal strength and have come across a guide about changing the firmware. My concern with this is that I mess it up and cause more problems. At the moment there is a distance of about 40' and a couple of walls in between my pc and router. I have a linksys wrt54gl router. On the signal strength bar there are 4 bars and I fluctuate between 1 and 2. Is there any other way to boost the signal before having to change the firmware. Many thanks.
