Linksys Cable / DSL :: WAG120N Constantly Disconnecting / How To Stop It

I got my WAG120N like 5 months back. Last night it started to disconnect randomly like at 5 - 10minute intervals.... The connection to the internet connects and then disconnects within 5 seconds. I've tried resetting, firmware upgrading, restoring settings and all that with no success. (I'm referring to the wired connection used for my PC and not WiFi) 
 
Here is a copy of the log
