I'm facing a very similar or identical issue. I'm on a brand new Lenovo IdeaPad 110 with the same RTL8821AE wifi chip.
WiFi works at first but dies after a couple of minutes. If you wait for a long time it will recover. Ping behavior is similar to what's seen above, except the error message is "No buffer space available". Larry Finger's drivers do not fix the problem, nor does disabling power saving through module options as described above. I have a Linksys E2500 router. With 5 GHz disabled and 2.4 GHz set to Wireless-G Only mode, the laptop's WiFi works, but everything is really slow. The interface says it's running at 54 Mbps, but ping replies are being delayed by several seconds. SpeedTest says 19.71/0.43, which is the worst result I've ever seen on this WiFi network. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577111 Title: RTL8821AE wireless adapter sporadically stuck (rtl8821ae module) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1577111/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
