Public bug reported:
Hi all,
My wifi connection disconnects constantly when I am connected to an
eduroam/govroam access point (protected EAP, MSCHAPv2).
The wifi driver is: rtl8812au-dkms.
Linux Xubuntu-18-04 4.15.0-22-generic #24-Ubuntu SMP Wed May 16 12:15:17
UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821AE
802.11ac PCIe Wireless Network Adapter
Symptoms: the (eduroam) wifi-network is found, the wifi connection is
set up, it works for a bit and then the connection is dropped.
If I use my Android phone (which connects fine to the eduroam
connection), to tether my laptop, the connection is fine.
Also my laptop connects flawlessly to my home connection (WPA).
In kern.log I see messages like this (redacted the mac-address):

I have been using 18.04 without problems (and 16.04 before that) until
recently; so it seems the problem is recent.
If there is any more information I can provide please let me know.
