Bridge: No Internet Connection

I bought the combo-package at Hornbach and replaced it today with a new one (from Hornbach) because the bridge did not work (see first posting). Now i got a Bridge with FW 2.1.22, so new version i think.
Bridge is still not usable because of the well known http 503 error (Random "HTTP 503 Unavailable")

FW update is not done yet by the bridge… How long does is take normally?
