So, also here on this thread due to loosing Mesh capabilities with the 3.203 firmware uodate.

I’m running a S1300 (master with USB/Wan internet) and a B1300 (slave), which both worked flawlessly prior to the S1300 taking the update.

I’ve reverted the S1300 back to Firmware 3.105, but following the mesh setup, ad I have successfully in the past, I loose the ability to access the S1300 GUI when the router is in mesh mode, following the rollback to the 3.105 firmware.

Possible that a plugin got lost in the mix? Any suggestions?
