RAX120 Slow Wifi Speeds

Sadly, I'm not sure Netgear is going to determine what the problem is. I had to buy another router to get a stable connection back, since my RAX120 was beyond the return window before I realized how bad this would be. I've been watching for almost 7 months now and testing each firmware and all solutions I find listed in the forums even including ideas people came up with for fixing RAX80 issues. Nothing has had any impact at all on the issue of AX Wi-Fi adapters slowing down randomly between ~5 minutes and ~24 hours when connected to the RAX120, up to and including disabling AX on both the router and the adapters. The issue does not affect any of the non-AX adapters or devices I own, but affects both completely independent systems when using either of my AX200 adapters. It doesn't affect either of those devices when using a different non-AX Wi-Fi adapter.

I've spent around 40-60 hours working with this particular unit including working with Netgear tech support hoping to find the root cause. Unfortunately Netgear doesn't seem interested in determining the source of the problem. The main response is pretending that another several hours of going through level one scripts will somehow work this time, and failing that the response is dismissal as something I must have done or be doing wrong, everything from "maybe your microwave is running" to "your signal must be bad". If they had any real interest in resolving the problem, they'd have engineers, not level one support, working with me or one of the dozens plus other people with the problem, and gather detailed debug logs to be reviewed.

If any Netgear engineers actually read this forum, feel free to reach out to me directly if you want to bypass your tech support, who have been stonewalling anyone trying to get to the backend teams, and work towards an actual root-cause analysis on the issue.
