Question 1

Install fails or rolls back?

Accepted Answer

Unplug the WU150 1, run the Sempre setup as administrator, and temporarily disable antivirus. If Windows blocks the driver, install the INF manually via Device Manager > Update driver > Browse. Confirm the driver matches your Windows version and WU150 hardware revision.

Question 2

Adapter not detected?

Accepted Answer

Use a rear USB port directly, not a hub. In Device Manager, check for an unknown USB device or WLAN adapter; uninstall it, reboot, and replug. Disable USB selective suspend for the port.

Question 3

Version conflicts?

Accepted Answer

Remove any older Sempre/WU150 driver and vendor Wi-Fi utility, delete hidden WLAN adapters in Device Manager, reboot, then install the latest WU150 1 package. Keep only one Wi-Fi management utility active.
