Nighthawk CM2050V Comcast Firmware Killed Speed

Sorry.  You're fortunate yours is still working. No I won't feel good being charged monthly for a modem....always had my own. I do most everything myself, always have. I can't believe after trying to upgrade my old Arris Tombstone a few months back that worked fine, I cannot get a modem that works. That does not seem to be a coincidence reading the reviews on Amazon and Best Buy. The Arris T25 and the Netgear CM2050V are the only ones Comcast is recommending for my service that includes 2 VOIP lines. I have my own router. I live in the mountains with no cell service unless I walk 200 ft into the middle of the street so I need the telephony. When I make suggestions to the Comcast tech support people they act like they don't understand...they have their own agenda or procedure, so making suggestions to them is futile....it's always 2 ships passing in the night. They took a month to send me someone who knew what he was doing. The first guy was a contractor who did not even have the tools to do his job so he lied to me. The guy today was a real technician with a great attitude....the best tech from them I've had in 9 yrs. I'm really at my wits end with this s**t.  I've spent about 100 hours trying to find someone from Comcast who can get a modem working between the 3 modems I've tried.  I had to call back many many times until I got someone who could do their job.
