I think you can uninstall bios by restoring if you remember when it was installed, or while restoring it will show that at which date u installed bios update software. But now u explained and found that why this problem is being occured, then solution is to be found of wifi connection. I also have lenovo but since I did not install the wifi driver. I will install it then I will share the experiences too. If it is then we will complain to the higher authorities of lenovo on their len care helpline through their mail or on their spesific number 180042555554.
