I had something like this for some time a while back. Not knowing any better, I did nothing about it (nothing was affecting my PC, so it didn't seem to matter. Just the data-lights flashing almost continuously on the broad-band modem and the router in-LED). This situation continued for over a year. Performance didn't appear to be affected in any major way, just a lot of flashing LEDs. A couple of weeks ago, I got a new PC. In the process of setting it up, I disconnected the broad-band modem from the net for an hour or so. After getting up and running, I reconnected, and no continuous flashing.. All back to peace and calm.. Cheers, Diolma
