Hello Valentin,
When you uninstall the drivers from Device Manager, they are still present on the PC. So, uninstalling them you also have to check the Check the ‘Delete the driver software for this device’ box.
1. Did you try deleting the driver while uninstalling it as suggested in the previous post?
After uninstalling and deleting the device drivers, try installing the drivers that you want.
If you are still facing the issue after fallowing all the suggestions, I would suggest you to contact the equipment manufacturer and get the proper driver installed with their help.
Please reply back with the results to let us help your further.
Regards,
Deepak.
There no options to delete this driver because this is generic driver for group of devises I find him but can't delete him in system driver folder so I email to manufacturer but didn't received any answer and now my WiFi devise is useless - it is bad idea in Windows 7 to can't be used Installation Wizard like Windows XP - I try in my old computer with Windows XP to instal this WiFi and no was problems like this- driver of WiFi is installed by the program of manufacturer but it must be installed before Windows to instal the driver and in Windows 7 this is impossible - my be trouble is in manufacturer program for Windows 7 because she can't overwrite generic driver .So I my be sell this WiFi device because I don't use my old computer.
