I have my 5 node HH5a 22.03 rc4 mesh with roaming working fairly well, but with one problem which keeps cropping up.
It seems as though DNS is not getting served consistently to the AP clients attached to the mesh nodes (clients on the master node and cabled ethernet seems ok), the symptons are as follows:
Connecting to the master mesh node (which is running 21.02.1) via its AP everything works as it should all of the time.
Connecting to one of the mesh nodes results in no internet browser connectivity but I can ping the other nodes and external sites using thier address or name in the terminal command prompt.
Using the openwrt network diagnostic ping tool with a name results in a fail but entering an ip address 220.127.116.11 works fine.
From the above I conclude that the mesh nodes are not getting DNS settings, specifically they seem to forget them over night.
The strange thing is at step 2 using the command prompt on the client I can ping external sites with name or ip address and get a return.
I suspect I haven't got the DHCP / DNS setting quite right somewhere and would appreciate a little guidance.
