I was a very early user of the CM1150V (I can elaborate further, if necessary) and at the time it worked fine with my Xfinity service, but LACP was not yet enabled.
I switched to an ARRIS T25 last year, and later in the year, upgraded to Gigabit Xfinity service.
I noticed that LACP was supposedly enabled in the latest CM1150V firmware, so I swapped it in last weekend. The thought being that if all looked good, I would potentially purchase an LACP-capable router. I verified soon after activation that it had been updated to V2.02.04 firmware.
Once the CM1150V was activated, I experienced horrible stability issues, such as:
- The upstream LED would be solid for the first few minutes after boot, but before the first hour it would typically begin blinking, which I believe indicated potential low signal issues. My downstream speeds were as expected, but upstream speeds were about half as expected.
- The Internet connectivity would drop randomly multiple times an hour, for anywhere from seconds to minutes at a time. Most of the time when the connection was down, the Internet LED would still be solid green, but I'd be unable to ping the WAN gateway IP address.
I performed some troubleshooting with Xfinity and they did not see any issues.
I left the CM1150V in place for at least 24 hours and there was no improvement in stability.
I then removed the CM1150V, put the ARRIS T25 back in place, worked with Xfinity to activate, and my Internet connectivity is rock solid again.
Any ideas?
