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

Hi,

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 http://192.168.100.1 

 

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

Is this a WiFi connection ?
