[Bug 1536490] [NEW] rtl8821ae has no connectivity in 5GHz networks

 

Public bug reported:

Seems to be the same as
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1528005/

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 linux-
image-4.2.0-25-generic. make installed the above driver again and all
good.
