Seeking assistance with GT-BE98 Pro dropping wireless clients every couple of days.

[jrmoore1965]

I am having issues with a new GT-BE98 Pro running the 34491 firmware that is dropping all wireless clients every couple of days.  Rebooting the router is the only way I have found thus far to get them back online.  I am fairly certain 5GHz clients as well as 2.5GHz are being dropped.  

Asus Support hasn't been helpful.  I tried contacting them via the online chat and, without doing any diagnostics or even requesting logs, they suggested falling back to a previous firmware.  This seemed like an odd suggestion given that they'd done nothing to diagnose the issue.  An attempt to start a support ticket going via the router feedback pane has also proven unsuccessful.

If anyone has any suggestions on how to address this I'd be grateful.  Thank you.

Have you tried to hard/factory reset the router?

After this happens, you can still use the Web GUI and check which clients or radios and non-functional?

Can you pin the occurrence to any specific event or passage of time?   Reading the logs, if you wanted to do that, is made easier if you have some time frame when the event occurred.

Does the system have plenty of ventilation?

Have you made any changes to the default settings regarding such things as transmitting power?

Are you running the system using the MLO configuration?

Since you don't mention the 6 GHz radio, can we assume it is fairly normal and maintains connections?

>After this happens, you can still use the Web GUI and check which clients or radios and non-functional?
Yes. The Web GUI is still responsive and wired connectivity still works.

>Can you pin the occurrence to any specific event or passage of time? Reading the logs, if you wanted to do that, is made easier if you have some time frame when the event occurred.
Within a timeframe, yes.

>Does the system have plenty of ventilation?
Short answer: I believe so.
Long answer: It installed on a wire rack in a closet. There is at least a 2-3 foot clearance above the unit. I can try leaving the door open for a few days to eliminate the possibility you are suggesting. I'll order a temperature sensor on Amazon as well.

>Have you made any changes to the default settings regarding such things as transmitting power?
No. Setup each channel as a separate SSID, enabled OpenVPN, enabled guest network, reserved an IP for the printer, set Cloudflare and Google DNS are about the only significant changes I've made.

>Are you running the system using the MLO configuration?
MLO is currently disabled in the GUI. I have not changed it.

>Since you don't mention the 6 GHz radio, can we assume it is fairly normal and maintains connections?
Unknown. I do have a laptop that can connect to that frequency. I'll give it a shot.

I'm having the same issue that the wireless connection just drops after a couple of days. In my case, a reboot does not help but setting the same Pre-shared keys to the WiFi SSIDs solves the issue. It's like the Pre-Shared Keys are being forgotten after a few days. I haven't contacted Asus yet.

Updated answer:  Ambient temperature right next to the router is 77-79 degrees Fahrenheit.  Well within the recommended 32-104 operating range.  But, the router did feel pretty warm to the touch so I purchased a USB-powered fan and placed on top of it.  It has been a few days since I've had issues.  That's no proof that this helped but heat is always bad for electronics.  I'll post updates as I learn more.
This is the fan I bought.  Rather happy with it thus far.  It sits perfectly over the hot spot on the router and is quiet.
