Hello
I have a problem with my 5G internet.
We have a dualband router and i have a dualband usb wifi adapter (D-Link ac1900 usb wifi adapter).
I can connect to the 5G network with other devices. Its like i cant use a usb wifi adapter anymore. I have also tryed installing the adapter on other computers but with same problem. This is strange to me becouse i have been connected to the 5G network before, and then sudently it went down.
Things i have tried:
- Move my pc next to the router
- Using the troubleshooting tool
- Uninstalled/reinstalled drivers
- Restarting the router
- Resetting the router
- Restarting computer
- Give my pc static ip address
- Windows 10 clean installation
- Tried a diffrend usb wifi adapter
- Changing the channel of the 5G network
- Installing the usb wifi adapter on another windows 10 pc
Sometimes i get bluescreen telling me something about D_rtwlanu.sys.
Useing Google Translate to translate what the bluescreen says in english:
The computer encountered a problem and should be restarted. We must have collected error information, and then we will restart for you.
