I am receiving a massive number of “Correctable Codewords”, billions in short time period. Additionally IPv6 is unable to successfully negotiate. It would appear that there is no way to completely shut down the IPv6, but I believe that is a secondary issue.
My ISP is Sparklight. I’ve contacted them numerous times over the past few weeks, however since I own this modem, they claim that they can’t help, even though they point out that they do see some packet loss. The only thing they seem to be able to do is verify or perform a firmware upgrade. (I’m not sure how they are allowed that but can’t do anything else).
Sparklight had previously replaced the cable between the pole and my house, and adjusted signal levels. I finally got them to send a Sr. tech out this afternoon but not holding my breath on a fix.
It’s a little disappointing that this modem, after being on Sparklight’s recommended list and only being a couple of months old is having such problems with connection. Is it Sparklight, or is it the modem?
I am in process of getting a different ISP with a Fiber system. Hopefully this will resolve the problem, but until that gets connected and verified with the G34, I’m stuck using my cell phone hotspot.
Yes, it’s got the latest firmware.
It seems the vast number of codeword corrections and the failed IPv6 attempts are loading the modem CPU so much that it won’t respond on either wifi or hard wire connection, otherwise I’d provide log information.
Questions:
- I’m told this modem will work on the new ISP fiber network, although I’m not sure how it’s supposed to connect fiber to F connector. Is it reasonable to expect this modem to work well on the fiber network?
- Even shutting down all of the IPv6 settings the modem will continue trying to negotiate. Why am I unable to completely shut off IPv6, or why is it not able to fully negotiate IPv6?
- Why can I not get a voice to communicate with ARRIS regarding these problems?
