All of my 2.4g devices drop and won't reconnect after a period of uptime with my Archer BE800 v1 on latest firmware. I have to either reboot, or disable and re-enable the 2.4g network, which is a pain because it causes a blip on the Wi-Fi which affects other devices, and I have to re-enable BE mode and re-enable 2.4g for MLO afterward.

I think this is a software bug, not a hardware problem.
 

I love the performance of this router, but I miss the stability of my AX6000 which would just run forever without a hiccup of any kind. This took about 3 weeks the first time for the issue to occur, then I rebooted to fix, then this time was after less than a week of uptime, to which I decided to try just restarting the 2.4g and that restored it to working status... I set a reboot schedule for a week after the first incident and it didn't even make it to that. I just changed it to every night as a workaround, but I think this is ridiculous. Please address in a firmware update.

Let me know if I can send your support a dump of all settings or any other diagnostic information to help with figuring out the root cause. If I need to enable any additional logging, please advise of that.
