Hello,

I have the AX5400 (Archer AX73 v1.0) and it has started to block all traffic between wired and wirelessly connected devices even though they can see that each other are on the network. I saw on another thread that someone suggested turning off the SPI Firewall which I tried with no effect. Any other suggestions?

Thanks for any and all input!

Edit: I can ping the printer from the router's interface and any wireless devices, but not from anything wired to the router. This appears to be an intermittent problem as I just tried to update the firmware for the router and my wired desktop managed to connect to the printer...for about 45 seconds. I do NOT have AP Isolation enabled and everything APPEARS to be on the same subnet.

Edit2: Updated from firmware 1.2.2 Build 20230119 rel.35540(5553) to 1.2.3 Build 20230303 rel.35540(5553) with no improvement.

Edit3: Updated from firmware 1.2.3 Build 20230303 rel.35540(5553) to 1.2.6 Build 20230526 rel.53018(5553) and tried a factory reset with no improvement.
