Hi, I'm currently running 19.07 and wanted to upgrade to 21.02, while doing that i had trouble setting up my WRT1900ACS as a DumpAP so I had to revert back.
All I need is to have all of my 4 interfaces talk to each other and also have 2 wireless radio (2.4+5) another router is handling the DHCP of course.
I tried to follow the guide but it seems like it is not applicable to the new version.
This is my network configuration today:
When you upgrade to 21.02 you should not keep the settings. There are a lot of changes in the configuration files and the network config from 19.07 is not compatible with 21.02.
In a nutshell 21.02 is using DSA instead of swconfig, therefore you'll need to fix the universal bridge from the beginning.
if your device has DSA enabled this may be of interest
it works on my MT76 2102 devices
paste this into you ssh sesion
& then you will have to find the IP it's been given
