** Description changed:

- Seems to be the same as
- https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1528005/
+ What is expected to happen is that when I connect my Lenovo Ideapad 300
+ to my ASUS RT-AC68U (firmware 3.0.0.4.380.1842) 802.11ac on 5GHz, it
+ connects fine, just like it does with Windows 10 home.
  
- 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.
+ What happens instead is that I obtain an IP address, gateway, DNS etc.
+ but no traffic occurs.
  
- rtl8821ae driver loaded. Connected to AP fine. Got IP address, GW, DNS
- etc correctly, but no traffic.
- 
- Workaround worked fine:
+ WORKAROUND:
  git clone https://github.com/lwfinger/rtlwifi_new.git
  cd rtlwifi_new
  sudo make install
  sudo restart now
- 
- FWIW, proper 802.11ac speeds copying large files.
- 
- Same problem after apt-get upgrade installed linux-
- image-4.2.0-25-generic. make installed the above driver again and all
- good.
