For anyone with Tomato connection troubles, try this adapter. TP-Link TL-WN422G which is based on a ZyDAS ZD1211B chipset according to the data sheet. It's a higher powered device than most (20dBm), and sports a removable 3dB antenna using a RP-SMA connector. Very good performance here through several concrete walls at 54Mbps connection speed, better than any other adapter I've tested. Seems to work well with Tomato on XP/Vista/Windows 7 and also supported by Linux (including injection) according to others.
