I installed the latest firmware (8cddba9) from robimarko (to whom many thanks for his efforts!), and encountered a strange problem, it seems, with ARP or smth like this. I haven't tried the previous versions btw.
I have 2 access points on the same LAN, in a common l2-domain. The second is the AX3600, which I testing.
When I switching wifi-clients (laptop or phone) from main AP to AX3600 with robimarko's owrt, there some time period, during which I can't access any resources in LAN behind AP. I can ping/access only AP itself, but no any other IP in my LAN. So the client even can't obtain DHCP settings, because my DHCP server is not on AX3600.
After few minutes connectivity returns by itself, and everything starts working.
If I reconnect client to the AX3600 again (just turn off and on Wi-Fi on laptop or phone), everything works immediately.
If I reconnect from AX3600 to another AP, everything works immediately.
But if I reconnect from another AP to AX3600, there is temporary problem with connectivity again.
I tried to replace AX3600 with another AP (the third device is at my disposal), everything works fine everytime, so somehow the problem is related with AX3600.
Any idea what the reason might be?
