Asus Rog Gt-AXE16000 connection issues

[killfront]

HI I have had this router running with no issues for years but all of a sudden a couple days ago it decided to start dropping connection the only setting i changed before that was i turned the QOS off but when i noticed connection issues i turned it back on and im still getting the same problem i have tried changing bios to an older version and that did nothing i am running my isp modem/router in bridge mode and when i just use the modem/router itself out of bridge mode i have no issues not too sure whats going on here

Any possible new source of RF/EMF interference?  I read the description of the new BIOS and besides JAVA I can't think of how it could cause issues with connection stability.

You don't mention who your ISP is or what type of service you have, but there is a possibility your ISP wants you to use their equipment.  Are there any special numbers on your gateway which may need to be entered on the WAN page of the router, in the ISP special requirements section?

Are you aware of any service upgrades your ISP has done recently?
