The yellow one should be MT300N or MT300N-V2 while the black one is AR300M.

There is a bug in the yellow one and you cannot load libsodium.so.18, but you can find libsodium.so.X in /usr/lib and you can just make a symbol link

X is some number that I cannot remember.

ln -s /usr/lib/libsodium.so.X /usr/lib/libsodium.so.18
