...EXCEPT for my wife's computer. I got her an Acer Aspire L5100 Desktop a few months back. It's running Vista. When it first turns on it works great. About 20-30 minutes into the session, it locks up. Initially I attributed it to standby with a USB Wireless-N connection and not restoring properly, so I disabled hibernation, standby, and even edited the Network settings to prohibit the card itself from sleeping. No joy...it didn't hibernate or standby, but we still lost our internet connection on it. The rest of the network plays fine. I also updated the drivers of course. Interestingly, I couldn't ipconfig release/renew to get it back, I had to reboot.
So...I decided to try a cat-5 connection via a Linksys PLE300 powerline adaptor. Same issues. Still requires a reboot after 30 minutes.
I'm obviously missing something stupid and I'm so deep in it I've lost sight of what it could be. Happy to provide any and all specs. The other devices work great on the network.
I do wonder if it's the firewall. I have a third-party firewall on her computer, but I know I Vista's is two-way. I think I'll remove Zonealarm and see what happens.
PS> I strongly believe it's software since USB Wireless and wired Gigabit cat-5 all have the same issue.
