why is the special tab different as yours....from where get you the driver?
Mine was just a sample (is Intel 7260AC)
Please stop reacting to every post, as now the valuable information is cluttered by one word posts....

Driver: Broadcom 220.127.116.11
I can see and use the 5GHz band on my non-AC router too. Asus AC and Netgear dual-band.
I'm a little suspicious that it's a Windows issue. Here's why: I could see 5GHz with the initial Win 8.1 OS. I clean-installed the Win 10 tech preview, and lost 5GHz entirely. 2.4GHz worked fine. Went back and re-installed the factory 8.1 then upgraded to 10 "on top" of 8.1. That retained 5GHz capability, and that's what I'm running now.
Granted the above was with '10 and may not mean anything, but there's some implication that something OS-related - perhaps a Win 8.1 update - could affect 5GHz operation.
When I get a chance I'll go back to factory 8.1 and do some more testing.

We have seen similar problems with the Yoga2Pro and the Intel7260 WLAN/Bt combo card;
both the N and AC version.
These problems were very much driver related.
Upgrading to the latest Intel drivers was causing problems most of the times.
Reverting to the latest released Lenovo driver (mostly a lot older !) would then resolve these problems.
Funny enough it would take some time to find the latest drivers, as Lenovo does not always update all their support pages ....
You can check yourself if all necessary drivers are available by going to command prompt en type:
