With the router in pure 802.11G mode, the interface just barely hangs in
there. When I run SpeedTest.net, ping times go through the roof, the
test sometimes gets stuck without completing, and the results are very
bad. Oddly, ping reports no dropped packets. Just severely delayed ones.
However, the

The iwconfig output above is from while the interface still works, not
when it exhibits the bug. Let me know if you want an iwconfig dump from

Now for the WiFi bug report on the new BIOS:
The problem didn't go away, as expected. They wouldn't ship a machine
without working WiFi. This is clearly a Linux specific problem, which is
why I'm reporting it in the first place. If a BIOS flash somehow fixes a
bug that only occurs on Linux, the bu
For others who come across this report, here are some crucial bits of
information about upgrading the BIOS on this machine:
1. Download the Windows BIOS update from the Lenovo support website.
2. Install innoextract (apt-get install innoextract) and use it to extract the
MS-DOS flash utility insi
I will perform the upgrade, but first, a message to Canonical:
The tone in these canned responses and pages feel somewhat patronizing.
You get the distinct feeling they were written by a person whose
patience and good manners have been worn extremely thin.
They have successfully delivered the rel
As for bad performance and eventual halting of traffic, it's still doing
it. Messages from the kernel are, as before, deceptively calm. Just
routine messages about association and authentication. Not an error in
sight.

Testing on the mainline v4.8-rc3 kernel, the first thing that happens is
that the NIC dies before I can even use it. Browser just sits there, so
I try to ping:

Public bug reported:
Computer: Lenovo IdeaPad 110

After a few minutes of mixed Internet use, the WiFi hangs and the
interface ceases to pass traffic:

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
