I have two questions for which the solutions for them may affect each other: I just received a pair of Linksys 7dbi high gain antennas and am going to replace the stock 2db ones on my WRT54GL. I was wondering what the optimal transmit power setting would be for these new antennas? At the moment, on the stock ones, I am only getting about a 40% signal strength from my pc which is located about 12 meters away (40ft) in another room. There are 2 walls in between. Tomato's device list page is reporting an rssi of -72dbm and a quality of 27 for that connection. The pc has a netgear wg311t wireless adaptor card fitted with a large 12db antenna. I don't know why the signal is this bad over such a short distance. I was careful to try and select a channel that was at least 4 away from the nearest strongest neighbour's (mine is channel 6 and my neighbour is using 11). I get frequent slowdowns, an erratic signal, jumping all over the place from about 1mb to about 48mb, and even disconnections to the point where the pc cannot reconnect and I have to hard reset the router. The signal strength of my neighbour's wireless router is much stronger despite being about the same distance away I even tried replacing the wireless adaptor card which only seemed to improve things marginally... ?
