Question Can´t connect to 5GHz net (win 10 pro)

[mickhell]

Hi all,
I recently upgraded my pc stuff and did a fresh new installation of Win 10 pro.
Lately I can´t connect to 5GHz wifi anymore. It worked a while at start but not anymore.
Did some search here on forum and google but nobody seems to have the same problem.

I can see all the 2.4 and 5GHz networks and I can try to connect to them but get the message "can´t connect to 5GHz wifi". 2.4GHz works fine, usually. Sometimes need to do troubleshooting and reset wificard.
I´ve tried to upgrade everything to latest drivers and so, but still can´t connect. I know the password is correct but still...

Stuff I use:
Asus Z170-E motherboard
M.2 SSD
Win 10 Pro
Asus PCE-AC68 Wireless-AC1900
ZyXEL P8702N router

What to do next?

Thats sign of driver issue, can you uninstall the drivers and let windows install its own one? If it installs try it, if it does not , i would suggets you to look for older drivers if there are some.

Tried several drivers now, but not really any improvement.

I had som 30sec 5GHz connection with this one:
ASUS PCE-AC68 utility 2.0.8.8
Driver version Number: 6.30.223.228
Support OS: Win10/ 8.1/ 8/ 7/ XP,
but not anymore. Back to 2.4GHz only working. I can see the 5GHz but just get the message "Can´t connect to this network"

Any more tips I could try?
