Hardware as reported in comment #15 [WLAN adapter (10ec:8821) in a
Lenovo Ideapad 110S-11IBR, Pentium N3710, 4GB RAM, 256GB SSD
(80WG005YGE)]. I checked some kernels - here are the results:
kernel 4.4.0-79-lowlatency : problem exists -> no data transmission @ 5GHz
kernel 4.4.0-83-lowlatency :
Please check if 4.8 supports the feature you want:
$ sudo apt install linux-generic-hwe-16.04
or 4.10 supports it:
$ sudo apt install linux-generic-hwe-16.04-edge
If both of them do not have 5 GHz you want, check mainline linux kernel.
Exactly the same problem STILL EXISTS in Ubuntu's 16.04.2 LTS recent
kernel (4.4.0-78-lowlatency). Hardware is the same WLAN adapter
(10ec:8821) in a Lenovo Ideapad 110S-11IBR, Pentium N3710, 4GB RAM,
256GB SSD (80WG005YGE).
Why has that not been fixed yet (after 18 months!) in the recent LTS
This fix worked perfectly on my Ubuntu 16.04 LTS.
I am wondering why this has not been integrated in this very last
version of Ubuntu?
You received this bug notification because you are a member of Kernel
Packages, which is subscribed to linux in Ubuntu.
Simon Naunton, it will help immensely if you filed a new report with the Ubuntu
repository kernel (not mainline/upstream) via a terminal:

Same problem here (yesterday, 2016-01-20) on a Lenovo Ideapad 300
(80Q7008EAU - 15.6" i5 8Gb 1TB) on fresh install of amd64 Wily/15.10.
Wifi worked ok under Windows 10 home that came with it.
rtl8821ae driver loaded. Connected to AP fine. Got IP address, GW, DNS
etc correctly, but no traffic.
