Re: Mysterious lower download speed with DOCSIS 3.0 modem

Another SB6190 user with these problems. Prior to changing my speed from 300/30 to 600/30, I was able to regularly get 330 down. Since "upgrading" to 600/30, I'm only getting 220 down.

Comcast/Xfinity tech support suggests the SB6190 isn't capable of 600 down because it's only Docsis 3.0 rather than 3.1 despite me getting speeds that exceeded this previously. I'd really like to avoid spending another $100-$150 on new equipment when everything I can see suggests the SB6190 is capable of these speeds. Perhaps I'll just badger customer service for credits.

And now my bill is going up for reasons.

Very disappointed but I have no other options in my area.
