Mobile Broadband & 802.1x Wifi ThinkPad Helix (3698-4UU) Windows 8.1

So after updating to windows 8.1, I can no longer connect to AT&T mobile broadband.  The AT&T app recognizes my sim card, but Windows shows no service no matter where I am! (even tested next to an AT&T tower).  I have the latest drivers installed from the Lenovo driver page, Sierra Wireless MC7700 - Gobi 4000 Software for Windows 8.1 (64-bit).  When it installs though it says Serria Wireless EM7700 not MC7700. Anyone else have this issue?


Next issue is I can no longer connect to my corporate wifi which is 802.1x PEAP ,certificate based MSCHP V2.  I can connect to other non PEAP wifis without issue.  So at work I'm tied to an ethernet USB adapter when not on my USB 3 hub.

Any help for the above issues would be much appreciated!


I have model #3698-4UU
