Hi. I'm David, and I'm happy to help you.
Reinstall the Wi-Fi driver as instructed below.
Before starting the procedure, go to the support area of your computer manufacturer's website and download the latest Wi-Fi driver.
(If you cannot find it, let me know the manufacturer and model of your computer)
Uninstall the current driver:
- Open "Device Manager" (Windows + X and select Device Manager);
- Expand "Network adapters";
- Right-click on the Wi-Fi adapter and select "Uninstall device";
- On the confirmation screen, check "Attempt to remove the driver for this device" and click "Ok";
- Restart the PC.
Install the driver you downloaded from the manufacturer.
As for the Driver Booster, you did the right thing by uninstalling it.
I suggest not using third-party software to update your computer's drivers. This type of software causes more problems than it helps.
Always install drivers downloaded from the computer manufacturer's website, using driver update software provided by the computer manufacturer or Windows Update.
Feel free to ask back any questions.
