R7800 Intermittent disconnects, then auto-reboots

I am about ready to drop this R7800 off the edge of a 20 story building.

 

Two, Three, or more times an hour I get disconnects from the LAN, and the WAN. On the 4 port LAN switch of the R7800 I can see traffic as devices attempt to connect to either LAN or WAN but no other lights show activity, they all show steady white. After this continues for 20 or 30 secs the R7800 auto reboots.

 

All this happens on its own, I just stand there and watch.

 

The R7800 has worked without issues since May of 2019 (not counting the poor Netgear UI, UX firmware.)

 

I blew out the case in the hope that dust was causing an over heat issue. Not much dust, no change in ops.

 

I switched out the wall wart power supply in the hope that low voltage or too much ripple was causing misbehavior. No luck there.

 

Currently on firmware: v1.0.2.90
I’m about to down rev the firmware, but I’d rather not because of security issues.

As some others have been reporting similar fails, I throw the issue open for ideas from the group mind.

      Has a factory reset and setup from scratch been performed since last FW update?

       

      You can use Voxels FW on the R7800 as well:

      Thanks FURRYe38

       

      Re ISP: ATT (crappy, but no choice) residential gateway that provides Uverse via two bonded pair of copper.  The copper goes to the vault (a short hop) then goes by fiber (I presume MUX).  The RG is: Pace/Arris 5268AC   The RG logs show no uncorreted packet errors or lost packets, with low noise and good signal strength. Also good balance on the pair.  (I know most of the ATT outside wire guys by first name)

       

      Also note that this RG has been working well and relyably with the R7800 since May 2019

       

      Re Reset: Haven't done that yet, but it is on my option list, along with a few forceful hammer blows to the R7800.  The reset will have to wait until I have the time to massage the really poor UI.  I have reserved IP list for lots of stuff, and other settings.

       

      I have a back up of the settings but one thought I had was that there might be a conflict with current firmware and some old setting.  So if go through with a reset I don't want to just reload an old backup settings.  My thinking is that it is better to just go through it page by page.  But that will have to wait until I have the time and my fav shot of Whisky near by.

        PS:  Voxel is a thought, but I have yet to look into it.  One question comes to mind: can I reflash the NG firmware if I don't like the Voxel or is it a oneway street.
