Device description form device manager (should be real device name), not name from network connections (like on your screen)
My connection name is 'Połączenie lokalne', network device name is 'Połączenie sieciowe Intel(R) 82566DC Gigabit' and I want to this name. On previous W$ installation was correct name.
So, 'ł' = 179 and 'ą' = 185, both included in basic
ANSI characters set.
Result from DXE6 units is the same
BTW1: I don't uderstand what you mean with GetAdaptersAddresses?
BTW2: Is TMIB_IFROW available in DXE6, because I don't found?
