Howdy,

The network in our apartment consists of a WAN from a cable modem and a LAN, and i therefore use to NIC's in my main machine (so i don't have to enable file sharing on the WAN).

I recently build up a new system (specs in my sig) that basically consists of an a7v133 + a tbird 1.2ghz). I use an adaptec dual port server NIC

anyway, things worked great for about the first 2 weeks after building the system, but NOW, out of nowhere, i continually lose the connection to the WAN (i.e. the internet). the LAN stays up, and i can see other computers on the network, but my net access is down.

The way i restore the connection is to DISABLE the WAN and then RE-ENABLE it, and this gets my 'net access back up for about 5 minutes. but the really weird thing is that this tends only to happen during certain periods of the day. there's no pattern to it . but i KNOW it's not our network on the cable modem because NO ONE else in my apartment has this problem.

Any ideas? i tried re-setting the cable modem, and i've rebooted several times, to no avail. This is SOOOO annoying, reminds me of the days when our cable modem access sucked, but ATT has truly made big improvements over the past 2 years.

Sounds like an IP address conflict issue or a cable problem. Do you get an address via DHCP? If there's someone else on your network that's using your same IP you could run into this kind of thing. Even if they turn on their machine then turn it back off right away it could cause this kind of thing.

well, i use a static IP (i lied and told @home i run linux..which DOES support dhcp, but they don't seem to know that)

so i assume i'm the only one using this IP, but that's something i'll look into, because i didn't think of that and it makes sense!
