Comment 0 for bug 1536490

Seems to be the same as

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
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.
