intermittent internet connectivity

I had a "power failure" of sorts last night that may have damaged my Linux machine. I woke up to the chirping sound of the UPS that the DVR is plugged into. I was still a bit groggy and instinctively turned on the light. It came on, but was only about half as bright as usual. Seems there was SOME power coming in - enough to power light bulbs, but not enough to run anything with any substantial power draw.

Anyway, today my wired Linux machine is having sporadic success accessing the internet. I have a wireless router with 4 wired ports. My win7 "wired" machine is fine, as is my win7 laptop (wireless) and my wife's win7 laptop (also wireless). My smartphone can connect wirelessly. I plugged the cat5 from the Linux machine into my laptop and that works fine as a wired machine.

I have an EDIMAX wireless adapter and tried plugging it into the front USB port on the Linux machine. Same result. I can type in a URL and go there immediately, and hit refresh and it sits there "waiting for...". It may take 30 - 40 seconds to connect again, or it may not connect at all. I pinged several sites and get maybe 45% to 67% failure rate.

The ethernet jack is on the mobo. I thought about disabling the onboard card and buying a new card, but since even the wireless adapter doesn't work I'm wondering what's going on. Is it time to build another one? It's about 5 years old.

Thanks.

Don't panic.

Shut down your Linux box and your router at the same time for about 30 seconds or more. Start the router first and allow time to come back online, then start the computer.

Try the your test again, using web sites that you can access with other devices.
