I am thinking the same. I went through weird issues also and the fix was "nvram erase && reboot", and once the router was back online, using an ethernet connection to manually set my configuration.
If you want to try this route, I suggest flashing the latest build, then do the erase and reboot. Set your configuration on the latest build. After I did this, all 'weird' issues went away. _________________ Netgear R9000

My wireless settings have worked flawlessly (for the most part - only issue is with TurboQAM if enabled - so I leave it disabled).
For the erase command, does the && do anything special? I did a "nvram erase" on it's own line followed by a "reboot" on the next.
I might try a reset using the reset button (as that seems to populate default settings). Otherwise, perhaps a flash back to Linksys stock fw and reset and then back to dd-wrt.
Another question for other EA8500 owners - are your WAN and LAN MAC addresses the same (under Sys-Info)?
Without any settings or steps to reproduce... I remember the DD-WRT binary, or wireless firmware type,
had issues with QAM256 long ago. Vanilla firmware no problem but I keep TurboQAM disabled over here.
&& allows multiple commands in a single line so commands are executed immediately one after another.
There should not be a need for stock firmware. LAN, WAN & Wireless MAC are different and incremental.
Hardware reset button 10 seconds, nvram erase && reboot or WebUI Administration -> Factory Defaults
but an end result should be the same. nvram erase && reboot is enough, avoid using old erase nvram...
Since your fallback build is about a month old I see no reason to reset again just focus on configuration.
Looks like all my issues are related to Multicast/IGMP with the new IPTV hardware.
I had a unmanaged gigabit switch in my setup (in another room) that wasn't playing nice. I've since replaced it with my older DLink DIR-862L running DD-WRT as a switch only (radios disabled).
I've enabled IGMP Snooping on both DD-WRT routers and things appear to have settled down.
Currently running the latest build v3.0-r49418 (07/04/22) on both routers.
Only issue now is with the DLink and getting the WAN port to be part of the switch.

hello @sumbuddie,
I have the same EA8500 running on a direct gateway instead of using the Frontier gateway. It's handling well over 8k of connections from torrents and i remembered if i dual nat the connection using Frontier's router, it would perform poorly because that was where all the connections were limited by the Frontier gateway.
Try and re-flash using this r49392 build because it's running well on all three of my EA8500. I have Two WAN APs and one WPS router repeater, all EA8500. Do a reset all to defaults during re-flash. And avoid the Fontier dual NAT. Frontier's router works better on the LAN as the the WAN connection works even better on the separate subnet on the EA8500.

I guess I'm the only one with issues - perhaps I've got a failing device.
In any case, I decided to reset to defaults (using the GUI option) and reconfigured without any improvement. I've now reset using the erase nvram command via SSH and reconfigured.
Things started working well, but I was still having issues on the 5GHz band - traffic simply wasn't routing correctly on it (could connect, but no internet access). 2.4GHz was fine.
Eventually the device appears to become overloaded where everything just stops (even traffic on the wired switch is hung/lost).
I've rolled back to 05-27-2022-r48972 which seems stable for now - everything after this seems to give me issues after the reset.
Now, I've also changed/upgraded my network recently (updated connection from ISP with new Modem/Gateway), but it was working fine until I tried this update. I also introduced IPTV hardware which could be increasing the amount of traffic on my network and overwhelming the unit.?
