I have a WRT54G with Firmware Version: v3.01.3 - HyperWRT 2.0 and a PC upstairs about 15-20 metres away from the router. a couple of walls in the way, couple of large bits of furniture etc. I've run a seperate higain antenna from the PC away from the speakers etc and I'm getting 1 bar off the top of the windows zero point service graph. Netstumbler refuses to give me any useful information from the card. Unfortunately the signal randomly drops. If I move the aerial slighly (the one on my desk) signal decreases quite dramatically. I'm probably going to try and replace the card in the PC (currently a Hawking 54g), but first I'm looking at replacing the antenna on the WRT54G. Any ideas what connection it uses on the two stubby antenna? Any recommendations on a good antenna/setup I should use? btw - fantastic, a tech forum that leaves itself open without forcing me to open _another_ account in a place I'd rarely visit! Thanks for your help.
