A whole year and a half later I encounter the same problem.
I recently moved my computer and needed a wireless adapter for my computer. (Netgear N600)
Still no fix?
Its pretty lame seeing a grey dude as other peoples profile pictures, however I can see some and I've noticed that they are using messenger from their phones.
It is clearly only for aesthetics and it may seem sad that I have resorted to leaving facebook on in the background to make it look less dull. (Maybe I should resort to facebook chat entirely)
Can anyone help?
