My WRT54G (firmware v7.00.0) is connected to cable TV modem usually the wireless connection works fine, but after swiching off and later on the power to WRT54G a laptop cannot establish connection to internet. I can see in Odyssey software (for wireless connection) that my laptop found the right network (SSID) but in status it says 'waiting for keys'. I use WPA2 (TKIP). The laptop does not connect to internet. When I connect it by cable (ethernet) the internet works fine, I have noticed that by accessing the webpage-utility of the router and simply clicking save changes on wireless-settings page (without making any changes in the settings) my laptop instantly establishes wireles connection and everything works fine till next power swich-off.
