AC-7260 cannot connect to enterprise WiFi networks

Hi all.

Recently acquired a Lenovo T440 that has an AC-7260. I have been unable to connect to wireless networks that use enterprise authentication (requires a username and password, which then issues a certificate).

I am able to get to the fields that allow me to enter my username and password but the connection/authentication ends/fails and never downloads the certificate. I tested on two different networks (at work and at school) with credentials that I confirmed to be valid (I tried on someone else's laptop).

I have tried on both clean installs of Win 7 and Win 8 (8.1). Tried with the full software suite for the WiFi and just the barebones driver. All failed.

Any insight on this would be appreciated.

Thanks!

Hi lianw, I assume you are using the latest Intel® Proset Wireless Sofware version 17.0.

Can you comment on the encryption/authentication being used and if you tried with a different wireless driver version?

Hi Joe, thanks for responding.

I have tried the driver that came with the laptop (16.x) and 17.0 and both failed.

When I use the Intel ProSet utility to connect to either network (at work or at the university) that are not working for me, the utility shows: "Only a portion of the advanced 802.1X security information was detected. The following security screens will display our best estimate."

The screen that follows shows:

Enterprise security

Network Authentication: WPA2 - Enterprise

Data Encryption: AES - CCMP

Authentication Type: PEAP

PEAP User:

Authentication Protocol: MS-CHAP-V2

User Credentials: My credentials (that I have confirmed to be valid since they work on other laptops and mobile devices).

Did you install the additional components/extensions offered by the Intel® Proset software installation? These components can be added by using the Change option in Programs and Features or uninstalling and reinstalling the software in custom mode.

I did do that. I always go bare-bones driver for everything, but because this has been giving me so much trouble that I installed everything but it still will not connect.

It can't be the laptop itself as a coworker has reported the same issue on all T440 laptops (all part of the same batch we got from Lenovo).

He is still using the stock image (Win 7 Pro) and cannot connect to enterprise networks either.

I am on a somewhat-fresh Win 8.1 image and can't connect.

I will try using another mini PCI-E wireless NIC in my T440 and see if that works.

Is there some update regarding this issue ? Did someone successfully connected to WPA enterprise ?

I have no luck with Windows 8.1 or Linux and I'm probably not the http://ithelp.port.ac.uk/questions/385/Known+issues+connecting+to+the+wireless+network+(Eduroam) first one.

lianw, it is unlikely to experience this issue across different operating systems and Intel® PROSet Software versions. I suggest you contacting the system manufacturer since your issue could be hardware related.

pakr, you may try using any of the 16.x versions that are compatible with this wireless adapter.

The following document lists the supported adapters for each version:
