Solution: This may have many causes, e.g.:
WLAN card faulty:
to check this, open SDconnect, remove and reinsert WLAN card, swap with another approved WLAN card, if necessary. If the LEDs on the card do not light up, the card is probably faulty and you should purchase a new one from a specialist store.
If the cause is not a fault in the WLAN card, e.g. as shown when swapped over, please connect the two systems by cable. If a wired communication does work, the error is either in theIT network(please contact your network administrator) or in the Configuration (please contact the Star Diagnosis User Help Desk (UHD))
