sb6190 intermittent with spectrum

Hi,

I’ve had the sb6190 for a number of years without any problems, using it with a netgear nighthawk, until maybe a couple of months ago i noticed the connection was dropping off but not a nuisance. The last few weeks it’s become intolerable.

I called spectrum and the first agent said they could see the modem no problem. They wanted to send a tech and of course charge if anything beyond checking their end.

I hard rebooted everything but it didn’t last. I had replaced the cable on my end with rg 6 high speed a few years ago.

I called again and this time got an agent who knew what she was doing. She saw from their log that the modem was disconnecting from them off and on over the past 24 hrs. She also saw that the modem was flashed with docsis 3.0, she reflashed it with a docsis 3.1 but said she didn’t know if this would be only a temp fix. It was. She recommended that i may need a new modem.

I had also read that the fcc had gone after the sb6190 for problems.

I looked at arris’s new sb8200 but when i went to ebay there were more for sale being used then new which i found unusual for such a new modem.

Is the sb8200 worth it?

Has anyone reflashed their sb6190 with docsis 3.1 with success if they had connection problems before?

thanks
