I did find a setting to change the router to AP mode.
Once it rebooted, I lost connection to the router.
I do see all the computers on the network now. I think I have it set.
I am unable to connect to the wireless router setup page.
how would I find the IP address for the router.
Well, the easy way to find a routers ip address in windows is to do run->cmd->ipconfig /all and look for the gateway address, but I think you set it up as a repeater which is fine, but you won't be able to see it on the network any more.
If that is the case and you need to change some settings the only way is to reboot it, usually by sticking a paperclip in the little hole, reconfiguring your settings and resetting it as a repeater.
