Recover xDsl Router TG788vn v2 Password

Then you're not providing enough details, tried a few combinations with md5("$user:Thomson Gateway:$password"), but didn't get any match, try with the shortest username/password to identify what the algo exactly is.

You should be able to figure out what that "crypt" thing is pretty easily.

Do you think that's salt?

Finally your usage of hashcat, as seen by your command line doesn't match what you are assuming to be the algorithm (not taking into account the salt/username)

You should do some more research I guess.

I'll try, but my knowledge of cryptography / programming is very poor...
