Surface Pro 4 WLAN (wifi) issues

[humml1]

Hello,

thanks for your reply. I tried to change the priority but it didn't work. The issue is not the local area network (which I don't use), it's the WLAN. When display link driver is installed, then the wlan doesn't work anymore - it shows that it is connected, but it's not possible to ping a website or the router.
I also tried to delete the dell ethernet adapter, so that there is only the WLAN adapter. It also didn't work.

Kind regards,
Armin
