CM1150V modem frequent and long reconnects more recently - upstream channel issue.
Hi, I found this forum somewhat helpful and and going to post my experience troubleshooting a problem with the CM1150V. I have not found root cause, but seem to have resolved it for now swapping ou...

Thanks for your response, I'm aware of all the standard troubleshooting.
When wired directly with no splitters, it made no difference - it would disconnect often and take up to 20 Minutes or more to reconnect. In fact, it almost seemed worse, going beyond 20 minutes to try and establish a connection. It was provisioned 9 months ago when installed and has worked well up until recently, Does re-provisioning make any differences that might resolve this situation?
I don't understand why having ISP check signal on my line (coming out and measure) when another modem seems to work fine without disconnects for 2 days now? That would seem to isolate the problem to my cm1150v modem.
ISP said my cm1150v modem is working fine from their end with their online status check, although I suspect this health diagnosis is quite rudimentary.
Always good to have tech come and measure line quality, I could probably force them to do it, that usually takes some time. With a T25 working fine, with seemingly healthier upstream status, I'm having a hard time justifying a tech visit to save the CM1150v that has gone bad, or was bad from the beginning and recent operating conditions moved it to operate marginally.
If I had a rational explanation why the CM1150v might still be good, I might go through that trouble.
I don't understand your question on Orbi firmware version. the Orbis continue to run fine on my home network when cm1150v modem disconnects often from ISP. They work really good, best signal I've ever had here by far. Are there known firmware issues here that could result in modem connection to ISP frequently dropping? If so, maybe you could bring to light?

If a different modem works and seems to resolve the problem, then possible the CM modem could be faulty. Something to contact NG support about.
There are some versions of Orbi FW that cause problems. There is a reason for asking about FW version.

Thanks for your reply.
I may take up with NG as the burden will be on them now and may still be under warranty. I'll leave it here for others in case they run into similar issues.
I'd rather avoid disclosing too much about my network hardware and software. I already have logged a few "visitors" from time to time, showing up trying to crack usernames and passwords.

For troubleshooting and helping users out. It's ok to give FW versions. It helps us help you.
Good Luck.

Since it's been over 90 days since purchase, Netgear wants me to sign up for a service plan before they will let one of the techs work with me. Plan is refundable if they find their hardware at fault and will replace it under warranty.
So, this is gambling. I told the representative I thought they'd value knowing about a problem I isolated and want to study it. I suppose they get lots of calls about poor internet and it's not their fault in the end, so they need a barrier.
I decided to think about it. I may do a factory reset, provision again, and see if it recovers those upstream frequencies and/or holds the link. The "gambling odds" might improve with a few more hours invested if it keeps performing poorly.. Maybe when I get bored over the holidays....
