[...]The MT7601U chipset is not a recent one so it should not require a very recent kernel (in case Ubuntu has a more recent kernel that your Debian distros)
There is one notable difference, though, between your Ubuntu and Debian distros: there is no more i386 version of Ubuntu, so you are using a amd64 version of it but you are using a i386 architecture version of Debian on your amd64 architecture processor (with PAE). That could be the origin of your problems and I suggest you using an amd64 Debian: nowadays I would say that running a 32bits OS on a 64bits proc probably offers mostly drawbacks...
