Yes, I do.
Wasn't aware I could add more than 1 guest network per frequency (assumed it was for other types such as open access only)
With second guest network no internet access either.
Removed power cable for 5 minutes with no success.
Thx 4 very fast reply.
Using an Asus RT-AC5300
Updated from 384.19 (previous asuswrt-merlin version)
I'm not aware of option to add multiple guest networks, 2.4 and 5 GHz split aside.
I did not perform NVRAM erase.
My guest account does not work either anymore (no internet access) since updating to 386.1 firmware.
Rebooting does not solve the problem nor removing guest account and adding it again.
