My system is constantly losing its wireless connection. Same with my Acer Aspire One netbook and my Xbox 360. I have a WRT54GL router that I've flashed with Tomato 1.25 SpeedMod. Most values are set at default, except I've recently upped the Transmit Power to 70 mW. This had a moderate effect in wireless signal, as shown in the Device List page and in the program InSSIDer. I have my wireless set on Channel 1 as there seem to be a lot of neighbours in the area on Chan 6 and 11. I have security set at WPA2 with AES. My main system is an overclocked Q6600 on an Asus P5Q-E motherboard with 4gb ram. Both my main system and netbook are running Windows 7 RTM, but I had the same problem when they were running Vista Ultimate before. Any tips/suggestions?
