Arris CM820A - still a good modem? When to upgrade?


I purchased this modem a number of years ago (admittedly) I don't know how long ago. Getting on/off internet outtages, so trying to determine if it is worth upgrading this modem?  If it is the most current / best spec for Comcast?


Thanks for any thoughts.

It depends on the speed tier that you are subscribed to ?


What do the modem's signal stats look like ? Try getting them here 


Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

Is this a WiFi connection ?
