Netgear CAX80 combo modem / router. Router connection keeps dropping off several times during the day
I purchased this Netgear CAX80 in Oct 2021. At the time a high end modem/router ($400). I can say fairly OK for the last 17 months. However, during the last week (early Mar 2023) I've had to reset the modem multiple times during the day (3x) after loosing all the WiFi network connections. I have done the following w/o any successful results: 1. Changed the SSID name & paswords for all the netwoks 2. Changed the modem/router location 3. Plugged the modem/router directly to wall outlet (it used to be plugged to a power strip) Because the router is out of warranty I can't get proper support from Netgear Today, during another router outage I decided to test if hard wiring into the modem w/ ethernet cable I could get online. To my surprise, yes I was able to. So this tells me is therouter section (WiFi) of this modem causing the problem. Again, I had toreset the modem to get everything working again. This can't be normal Yesterday I called COX to check if they could help and the only thing they said was the normal ..."reset" ... which I know that resolves the problem temporarily. However, I shouldn't have to do that 3 or more times a day!!! Has anyone else run into the same problem? What solutions did you apply to fix the issue. Much appreciated for the forum feedback

Netgear Orbi CBR750 Wi-Fi 6 DOCSIS 3.1 Mesh Wi-Fi Cable Modem Router - won't bond to more than 4-upstream bonded channels
I spoke to Cox sales & tech support prior to purchase of the CBR750 to verify this device is certified to work on the Cox network. - The Cox website actually features the modem-COX CBR750 page I have reached out though Facebook messenger, andcox.help@cox.com The issue is that we had a scheduled ‘upgrade’ to our service area in Apri 22, 2021 Our service areahad an additional 4-upstream channels added to allow for the full ‘8’ — the Cox tech verified today that his field modem was getting the full 8 — the above The CBR750is only locking Channel ID 1-4 The Cox webpage (link above) clearly states for the CBR750:“32x8 channel bonding” I need someone in Cox engineering to determine that the current modem firmware (V1.01.08.)does not allow for all 8 - upstream bonded channels with Cox cable.And or that my modem is correctly provisioned with theappropriate coding to allow for the full 32x8 channel bonding. I cannot personally provision these settings—or modify firmware.

Netgear CM-1000 Reboots at Same Time Every Night / Suspect Recent Firmware Update.
A week ago, I and at least two other Cox subscribers with Netgear CM-1000 modems began experiencing NIGHTLY modem resets -- multiple times per night, all at exactly the same time. Two of us are in San Diego, one in AZ. But the real issues appears to be the model of modem AND a recent (I suspect within the last 6-7 days) problematic firmware update. I have a hardcopy modem status page printed on 8/5/19 indicating firmware rev v3.01.04. CURRENT firmware rev is v5.01.04. WHEN was this revision pushed out?

Intermittent Wifi Connectivity Issues and SLOW connection
I pay for the premier internet service, but seem to get anything BUT... it's slow like dial up many times or just stops responding, which doesn't make sense since I can test my speed at times and see 35.9 mbps download and 6.88mbps upload. I know I have quite a few devices connected, which is why I pay for better internet service, but only 2 or 3 at a time that are actually streaming or internet browsing. I checked my channels and have adjusted to account for a lot of neighborhood cross-pollination, but no luck. Tried On my Netgear Gateway C3600BD modem logs, I see a ton of error logs. Any advice is appreciated. This has been ongoing for quite a while, and usually the response is to reset the modem, but that's getting old. 2018-01-06, 21:33:54.0 Critical (3) Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC=b0:7f:b9:b2:6a:78;CMTS-MAC=2c:86:d2:88:a2:ad;CM-QOS=1.1;CM-VER=3.0;
