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.

Workaround worked fine:
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 latest kernel  at time of
writing (sorry, my laptop is at home and I am at work, so no kernel
versions quote here, but more than likely linux-image-4.2.0-25-generic).
make installed the above driver again and all good.
