I keep getting a limited or no connectivity problem with my linksys router and comcast modem. The problem is reoccurring and is temporarily solved by resetting the modem AND the router. I also discovered last night that it sometimes fixes itself. I was online and then lost my connection, receiving the error message "limited or no connectivity". I restarted my laptop but to no avail. I was too tired to go downstairs to reset everything so I went to bed. This morning, my connection was ok. Also, as a side note, I often get an ip address conflict message. It does not seem to effect my connection though. Any help or insight is greatly appreciated.
