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 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....
Does your modem have a option that mentions Higher Power on the Connections page?
"Extended Upstream Transmit Power"
Also your modems Power and SNR should be around these values: What i have on my CM1200 currently
