RAX120 constantly dropping WiFi until reset

I have a RAX120 with factory installed .114 since Octoberish 2019 and since that time I have only experienced two (Recently within the last two weeks) total lockups with my RAX120. I don't know why it locked up, but a power off reboot has restored the RAX120 to operational condition. Yesterday, the second lockup time, I physically moved the RAX120 to a slightly different location to receive what I consider better air-flow for cooling purposes.

Other than those two lockups, I have had no issues with my RAX120 and I have been completely satisfied with its performance.

I want to help out here so possibly what I have to say will be of some use for others.

My Wireless Settings are:

Enabled AX

Disabled OFDMA 2.4 & 5

2.4G:

Enabled SSID

Enabled 20/40 Coexistance

Channel Auto

Mode Up to 1147

5G

Channel 153

Mode Up to 4803 HT80

So, there are a couple of "fine" points to realize when doing a firmware upgrade or downgrade:

1. Do NOT use a saved configuration file created from a different version firmware to update settings in the new upgrade/downgrade. If FW versions are changed, manually entering all settings is the absolute best way. In other words, using a .114 configuration file to restore settings in a .118 upgrade is a recipe for disaster.

2. It would be considered "Good Practice" when upgrading/downgrading firmware to first do a factory reset, then do your upgrade/downgrade, then do another factory reset, then enter your settings manually. Doing such provides you the insurance of a "clean" upgrade/downgrade.

I know it sounds like a bit much, but if you are having problems, sometimes the finest of details can be salvation.

3. Do NOT locate your router, or any other "Wireless" device within 6ft. of each other. The farther apart wireless devices are from each other, the better. Isolate these devices from each other. "Extenders" and "Repeaters" should be as far apart as possible, 30ft, 40ft, etc.

5. Be sure that your router and equipment have adaquate air flow around them to prevent overheating. Don't "Stack" equipment on top of each other, heat rises and whichever equipment is higher on the stack will get hot air from below. 

6. Locate your wireless equipment so that it can freely and openly propagate its WiFi signal.

I hope this helps.

I am waiting to see if my RAX120 is going to lockup again after I relocated it....
