Wifi can't connect when there are many AP for the same SSID

[EgU]

Hi

I'm uncertain if this is the correct package, please move if you think it should!

The story:
I just updated to Ubuntu 14.04 and soon noticed that it can't connect to my office wifi. This worked fine with 13.10.

After some testing I noticed that I could connect to my home wifi and to my mobile hotspot. All three using WPA2 security.

The only difference is that my office have several AP:s for the same SSID (To cover the whole office space) and my mobile hotspot and home wifi have only one AP.

I have generated wireless_info.txt from wireless_script to gather as much information as possible. They will be included in this ticket. The test is done at extract the same spot, just after each other.

wireless-info-single-AP.txt - Connected via my mobile hostpot (EgUSpot) currently in use for writing this ticket.

wireless-info-multi-AP.txt - While trying to connect to office wifi (Aurora, I think)

All passwords and so on is triple checked and they all worked before updating to 14.04 from 13.10

The laptop I test with is a Lenovo T440p with Intel Wireless 7260 chip.

I hope I got all the information you need to solve this, if not please ask and I will try to add the requested information.

/BR
