HH3000 constantly resetting (Internet/TV out) while trying to add or keeping new HP Laptop (Wifi 6) connected to wifi

[MrWheel]

I've tried to connect a new HP Laptop to our home network and once its configured with our wifi credentials, it connects successfully but as soon as it attempts to download windows 11 updates from Microsoft it drops our home internet and also knocks our Fibe TV STBs out of service.  HH3K recovers momentarily (sometimes a bit longer) and then intermittently drops again consistently.  Our Internet and FibeTV service becomes unstable.

Disconnecting the new laptop from our home wifi network brings everything back to normal and stable.

Any ideas on fixes to get this new Costco Laptop up on our home network!  I've rebooted the modem multiple times to no avail. HP laptop has the latest network drivers.

thanks for any help I can get.!

SOLVED! The Giga (4000) modem solved the problems. Now, with the new laptop wifi 802.11 setted to "ax" on the 6Gb/s, it achieves great up/download. Before, "ac" and "n" were causing the modem to reset. On the a/b/c, the modem was holding, but the speed was 1.8Mb/s (on a 1.5Gb/s deal).

I lost the battery backup feature of the 3000 modem in the deal, it wasn't as easy to get my "vap", 2262 tv recorder (pvr) and my landline to connect... also some other equipment I had to force the connection and some devices to see the 5Gb/s network (undiscovered).

I'm now ok.
