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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1528005 Title: 10ec:8821 rtl8821ae has no connectivity in 5GHz networks To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1528005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
