The steps above may resolve the problem, but if they don’t, you can try to update the drivers. If you don’t have the time, patience or computer skills to update the drivers manually, you can do it automatically with Driver Easy.
Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.
You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks:
1) Download and install Driver Easy.
2) Run Driver Easy and click Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
3) Click the Update button next to a flagged network driver to automatically download and install the correct version of this driver (you can do this with the FREE version).
Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
Follow steps above, the problem should resolve. If the problem persists, it might be not caused by network driver issues, in that case, try uninstalling any other new installed software and rolling back any driver if it’s an upgrade.
