I had internet set up in the living room and it operated flawlessly. We have upgraded to 105mb/s, 20mb/s down/up speed and got the cable TV.(both are installed in the living room) For some reason the splitter was causing interference so I've replaced splitter and it seemed ok. Now, the modem resets itself sporadically and the connection can be lost for hours (longest was 8 hours). A tech was over here, but he wasn't too much use. When I do get a connection, the upload light (using Motorola sb2161) is green when both down/upload lights should be blue signifying that something is wrong. By the 12th call I got tired of calling the techs and running through the simple set up as it did nothing. Posting all of my stuff hoping someone can offer some insight. The link is for the signal strength(when I have partial internet)
