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
