cisco 2600 router crashing

[colet]

I made a guest wireless network with a linksys wrt54g connected to our wired network via a cisco 2600 router. It's been working great for years until yesterday when the cisco router began restarting at random intervals all day.

I replaced the power supply with a spare and no change. I disconnected the linksys and the cisco has been up ever since.

Could malformed packets from the linksys be crashing the cisco? I'm leaving the linksys disconnected for the weekend. Might connect some other device to the linksys' interface on the cisco. If it crashes again, maybe I can blame the interface card.

Has anyone heard of this? Thanks for any tips.

I wouls suspect something like faulty ram . You would have to look at the crash files and run it thru the cisco analyzer if you have access to cisco's support page.

Thanks for the advice, vipergg. The router has been up since I last powered it on without the wireless router attached. I reset the linksys to factory defaults and reconnected it to the cisco this morning. Still no restarts. If the cisco crashes again, I'll check the memory.

Quick follow up: It turned out to be a bad fast ethernet card in the cisco 2600. I had plugged another device into the interface and the cisco began crashing again. Got a replacement on ebay for $30 and all is well. Thanks for all the feed back!
