Arris SB6141 Resetting

I have a Arris SB6141 that I purchased in 2015. For the past few months it has been resetting multiple times a day. My question is, has the modem gone bad or is it a signal issue with TWC/Spectrum. Here are the error logs and signal strengths

Re: Arris SB6141 Resetting

If your AC power is stable, either the external 12vdc 750 ma supply is going bad or the modems internal voltage regulator is shutting down. 

 Try a 1 or 1.5 amp 12vdc regulated one with the large center pin + to see if that solves the resets.

Thanks, Im going to get a Netgear CM500 at Best Buy tomorrow. Its on sale for $49.99. My warranty expired on the Arris anyway

Re: Arris SB6141 Resetting

There was a batch of bad 6121/6141 power supplies, Unknown of the mfg as there were several different 12vdc 750 ma ones shipped with them. Replacing them with 1.5 to 3 amp regulated supplies solved the issue.

But I've seen a fe 6141's cook the internal regulator that steps the 12 v down to 5 & 3.3 v...

both exhibit the same log error entry.

 Modems are cheap, as long as it's on the list and has at least 16 DS bonding you're good to go.

 All the 8 & 4 ch ones are obsolete and can't handle a bandspread of 24 and more channels that TW/Spectrum is running.

Re: Arris SB6141 Resetting

Thats what I was thinking. Why buy another power supply if its the modem.  I bought the new modem today and its installed and provisioned and it hasnt reset yet.  Granted its only been about 4 hours but fingers crossed.
