Hello everyone,
Nothing did help. Not the proposed steps above, nor replacing the device.
What did help a little bit was changing the settings as described on a German Microsoft site that can be found here.
The settings which were made (slightly changed quote from the linked page):
- 802.11a/b/g -> disabled
- Transmition Power -> Medium-High
- Throuput Booster -> Enabled
- ARP offload -> Enabled
- Fat Channel Intolerant -> Disabled
- Roaming Aggressivness -> Highest
- Preffered Band -> 5Ghz
The problem seems to be router related (in my case it is a vodafone router called easybox) but is not the fault of the router vendor as all other devices are working properly. Perhaps it is better to say that the problem is with the Surface pro 7 and its interaction with specific routers.
Hopefully Microsoft can fix this issue via a software update, soon.
At least it doesn't seem to be a hardware issue.
If I can assist in any troubleshooting please let me know.
Or give us a patch - that would be even better.
Cheers,
Tim
