Today I finally said goodbye to BT along with ADSL. Cable all the way from now on. Everything is installed and working but I have a small question. I have plugged the modem into the internet port of my WRT54GL and the internet is working fine. But the light on the front of the router corresponding to the internet is continuously flashing, non-stop. Even when there is no activity on the LAN or WLAN the light will flash rapidly. It will start as soon as the router is switched on and won't stop. Is this normal behaviour for this router/cable modem installation?
