You do indeed appear to have the exact same DWA-552 as me. Is it 
possible that the problem is with the way my older PIII AX63Pro 
motherboard is interacting with the card? The only difference I see is 
the latency on mine is 32 and not 168. Unfortunately, I believe it has 
been too long (and I no longer have the box) to return this card.

What version of compat-wireless are you using and with what kernel and 
on what distro?
