Hi,

I have a rtl8821ae wifi and it is almost impossible to use. Please
help. Here are the details:


[1.] One line summary of the problem:
rtl8821ae WiFi does not work

[2.] Full description of the problem/report:
Download speed drops down to 50KB/s or less really often. Instead of
2.5 MB/s connection speed, I have an average of less than 100KB/s,
with rare peeks up to 2.5MB/s and common dropdowns to less that
50KB/s. Latency is huge: if I pause downloading at the speed of 50KB/s
and try to download some very simple web page, it may take a few
minutes.

Router info:

Vendor Netgear
Hardware Version WNDR4000
Firmware Version V1.0.2.4_9.1.86
GUI Language Version V1.0.2.4_2.1.17.1

Router firmware is up-to-date, I've updated it a few days ago. It uses
2.4GHz b/g/n and there's no way to disable 802.11n or force only
802.11b/g usage. Other Linux devices work well with that router.

Was reported to Ubuntu here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1622293
Latest version of https://github.com/lwfinger/rtlwifi_new on kernel
4.2 and kernel 4.2 by default were having the same issue apearing more
explicitly: speed was dropping to 0, not to 50KB/s.
