Albania and Caucasian "Albania" (Aghbania) are two completely different things that have no relation to each other, with the exception of a name, the latter of which is (I believe) latinized. Ethnically, racially and linguistically, they are 2 separate peoples.
Montenegrins, Serbs, and others against the Albanians tend to perpetrate the argument that Albanians and Aghbanians are related to discredit the Illyro-Albanian continuity and try to eliminate the Albanian claim to Albanian-inhabited lands in the Balkans, especially Kosova.
The Albanians speak an Indo-European language, the descendant of the ancient Illyrian language, while the Aghbanians speak a Caucasian language. The only similarity is the name: but keep in mind during the middle ages Scotland was also called Albania ...
I'll see if I can find a more appropriate picture.
