Cut everything off. Turn on the modem and wait a minute or two after the lights stop changing and blinking. Turn on the next device, router in our case, and wait a few minutes again. Then turn on the computers. I always cut on the one hooked to the ethernet #1 port first but it may not matter. That was my Linux box and it was always on, 24/7. I also had to change the IP address on the router to a fixed address to get it to work right. I think I had it set to 192.168.100.2. After that, we had very little trouble with the connection. The modem itself was 192.168.100.1. If you hook your computer directly to the modem, you can see things like signal strength and stuff. Can't change anything tho. You just get to look. I think it had like a reset button too. Also, if I had anything between the computer and the modem, I could not see the modem at all. YMMV. Oh, we had Vista-Media to. If that matters any. May not help but may be worth a shot in the dark. Dale :-) :-) -- gentoo-user@lists.gentoo.org mailing list
