How does your router config differ?
I am running vista with an Intel(R) PRO/Wireless 3945ABG Network Connection and a 2wire wireless modem. I lose the connection randomly sometimes in less than 2 minutes after I log on. I can hear it clicking off & on, it will not reconnect without manual instruction to do so. I've updated the driver, moved the modem to clear line of site. No electrical devices nearby. I'm not clear on which advanced properties might be changed to help the situation or if my equipment is faulty. I've tried diagnostics, troubleshooter says might be a network adapter problem but device manager says it is working properly, any suggestions?
