What do you mean by “support Adguard Home”? I successfully run it in mine (incl. 2.4GHz and 5GHz wifi). Two or three devices do not seem to be a problem, I have not tried with more devices. But it doesn’t seem like it would have an issue with another two or three at least. Resource usage was not too high.
Of course if you want to run Adguard Home, you need to run it on external storage (e.g. SD card, USB stick…)
I was able to install AdGuard on GL-MT1300. Following the forum suggestions on AR-750 you need to add these two plugins: AdGuardHome and gl-agh-stats. After this step Adguard is working just fine, My router is on 3.203 firmware. AdGuard application and settings pages work too.
This is what I did:
-ssh to the router with ssh root@192.168.8.1
-find out where the microsd got mounted by looking into the /mnt/ directory. in my case /mnt/mmcblk0p1
-cd to the above directory
-download latest version with: wget https://github.com/AdguardTeam/AdGuardHome/releases/download/v0.106.3/AdGuardHome_linux_mipsle_softfloat.tar.gz
-unpack with tar xzf AdGuardHome_linux_mipsle_softfloat.tar.gz
-change symbolic link to this new executable with ln -sf /usr/bin/AdGuardHome /mnt/mmcblk0p1/AdGuardHome/AdGuardHome
