Question about Arris SURFboard SB4200 Modem
Several times a day this Motorola SB4200 simply drops my connection and the "Online" and "Activity" light go dark. I have to uplug both the power and ISP provided cable connection from the back of the modem and wait several minutes before re-connecting them. After doing this, service is restored for several more hours. This is a daily battle that I am absolutely sick of fighting.
There are plenty of aftermarket Cable Modems for sale at most major retailers (Best Buy, Target, Walmart, etc..)
I would go and buy a decent one of these and try it out to really test to see if the modem is indeed the issue here. If the new one works and doesn't drop the connection anymore then problem solved. If however the new one does do the same thing I would check for proper venting area (make sure you don't have anything on top of or burying your modem) first. If that's fine then it could possibly be issues with your actual line and in that case you'll need to harass the cable company until they actually send someone to test your lines.

I had a similar problem for a long time. The culprit was my TV. It was leaking voltage out of the tuner and down the coax which ran to the splitter my cable modem was on. The voltage was messing up the modem - thus the drops. The fix was put a 2X splitter on the inbound cable, 1 out goes to the cable modem and the other goes to a grounded multi splitter for the TV's. This did the trick for me.
