Running 4.4.0-64 in 16.04. This is definitely a flaky wireless driver.
If I turn it off, and back on I cannot browse any ssids. If I suspend
and resume, I cannot browse any ssids. I have recently added the options
to the /etc/modprobe.d/rtl8821ae.conf file "options rtl8821ae ips=0
fwlps=0" It is improved, but can sometimes resume and not see any ssids.
I am using 5ghz.

Considering buying a better supported wifi a-c/bluetooth card. Maybe an
intel card?

Title:
10ec:8821 [Asus X555L] RTL8821AE doesn't work after some minutes.
Status in linux package in Ubuntu:
Confirmed
Bug description:
My laptop is an ASUS X555L and I have a wireless card RTL8821AE. When WiFi
connected via 802.11b to my Vodafone router:
Product type HG658c
Hardware version HG658BZV VER.A
Software version V100R001C172B227
after a few minutes it hangs and doesn't let me surf internet although
it shows connected. With Windows 10 on the same laptop the WiFi works
seamlessly.
I tried the following but it didn't improve the situation:
+ Disabling power management:
iwconfig
wlp3s0 IEEE 802.11 ESSID:"internet"
Mode:Managed Frequency:2.437 GHz Access Point: 20:08:ED:7A:18:A4
Bit Rate=11 Mb/s Tx-Power=20 dBm
Retry short limit:7 RTS thr=2347 B Fragment thr:off
Power Management:off
Link Quality=66/70 Signal level=-44 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:17 Missed beacon:0
+ Changing WiFi to 802.11g or 802.11n. 802.11b is more stable but still has
issues.
+ Changing encryption type from WPA-PSK to none.
+ Bringing the laptop in the same room as the AP with no obstructions in
between.
