NetGear CM1000v2 FW: V7.01.01 - Regular (and I mean regular) Internet Issues
I am not sure when these issues started happen, I am sure it was not immediately when I connected the CM1000v2, possibly after a firmware update but I cannot confirm that.
What happens? My internet dies, I wake in the morning and notice a non-responsive internet experience and do a "SpeedTest" and notice an almost dial-up download speed of less than 1MBps. To remedy this I turn off my modem, unplug the cable, wait 10s, plug the cable back in and turn the modem on. This worked all the time until today (01/10/2010) when the first manual reset did not work and I had to perform another. Regardless, the modem and the router are both reset at 2am every night and this should be enough to "blow the gremlins out of the system".
I have phoned Xfinity customer service often, I have had engineers come out. They larrive when the interne tis responsive and they leave when it is still responsive. There needs to be a permanent solution; NetGear tells me this modem works on the Xfinity cable network and you guys do not tell me otherwise.
To add to this in a hope someone can shed some light on this matter, the modem logs (which are not great, in that they overwrite entries) tells me there is a lot of this
`SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing`
and a lot of this
`No Ranging Response received`.
