My SBG10 drops connection multiple times a day. I wanted to call to for support (since it's under warranty), but the only phone number is the premium one.
It drips multiple times a day. Often for an hour or two at a time. Power cycling only offers an intermittent and temporary fix.
The Xfinity technician said there are a lot of T3s coming off of it. The issue is not neighborhood noise.
The signal strength also fluctuates wildly.
