Wifi adaptor not working with mobile wifi device after upgrading to Windows 8 Pro

I have recently upgraded my office laptop (Previously Windows 7 64-bit Home Premium) to Windows 8 Pro online. Installation worked fine and Windows 8 booted - on my next day to office, I realized that it does not work properly with my Office Mobile Wifi Router.

On first I thought something's wrong with router, however it's working fine with other devices, tablet and phone, just like the previous day hence realized this is some driver issue with wifi adapter driver on my laptop.
Following is brief information about my machine details and what I tried. Kindly provide me help asap.
i3 machine with 6GB RAM
Lenovo Thinkpad Edge E420
Wireless LAN - Broadcom 2x2 11a/b/g/n Wireless LAN PCI Express Half Mini Card Adapter
The Wifi is working fine with my home wifi network (ADSL2+ Broadband) but just the mobile wifi router. Through some forum I thought I should revert back to Lenovo provided drivers "however everytime I try to uninstall driver or disable wifi adapter, it gives PAGE_FAULT_IN_NONPAGED_AREA blue screen error and restarts computer"
I believe it has something to do with improper wifi settings during Windows 8 Installation but could not figure out what to do. Any help would be greately appreciated...!!!

Hi, ritmehta


I think you're on the right track with the wireless settings, since the router works for everything else connected to it. And to hopefully stop the occurrence of the error and associated blue screen, I would recommend trying to boot into Safe Mode with Networking. This should allow you to be able to uninstall the device without the computer going into a blue screen. 


To enter Safe Mode, either restart your computer or start from a cold boot. Begin tapping F8 repeatedly at the splash screen and continue tapping it until you see a menu appear. There should be several options. Select Safe Mode with Networking. This will boot your machine only using the core drivers and devices, as well as the network ones. 


Best of luck, and let me know how it goes
