Newbie My WRT54G has a V.3 suffixed to the model number on the bottom of the unit. I assume this indicates a hardware version 3. Within the configuration pages, if I "Backup" the current configuration, the generated file name is WRT54GV2_v3.03.6 which seems to indicate that my router is a version 2. I'm in need of upgrading the firmware to obtain WPA2-AES support. I downloaded firmware v4.21.5 for V3 hardware from the Linksys site and applied it. It caused connection initial negotiation problems. I've reverted to the original v3.03.6 firmware. I'm questioning whether I should have grabbed V2 firmware updates instead of V3. Anyone have any insights?
