I'm not sure whether this has to do with my cable connection or with the Motorola SB4100 modem but today I got home from work and there was no connection, so I had a look at the modem and all the lights were on except the activity orange light. I checked the cables going to my Wireless router but nothing seemed wrong there. Then I tried to turn it off but it wouldn't responde so I had to unplug it from the wall outlet to reboot it and it worked however this has occured 3 times since then. I called Telstra and I asked if there were any problems known in the Chch and they said no. Could it be the modem turning sour?
