Title:
WiFi disconnects continually (goes "down" in NetworkManager)
Status in Ubuntu MATE:
New
Status in linux package in Ubuntu:
Incomplete
Status in network-manager package in Ubuntu:
Confirmed
Bug description:
Hello everybody and thank you in advance for your help. After a
recent update, my machine rebooted and appeared to be fine, but after
a short time the WiFi dropped and the NetworkManager applet shows that
the interface is down. I am also getting prompted for a password
(which was previously saved) and when I click on connect it will
establish the connection for a short time, but then goes down again.
In some cases this is immediate in others, I will be online for up to
approximately 15 minutes before it goes down again. I have tried
restarting NetworkManager, but I get the same results (short time up,
then down). I tried to review log data, but I am not a linux expert
and so I'm not sure that I am looking at the right log, nor do I know
exactly what to look for. Here are some lines from around the time of
the disconnect and the restarting of NetworkManager:

My Wireless NIC is (I think):
bryan@bryan-HP-Notebook:~$ lspci | grep -i wireless
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188EE
Wireless Network Adapter (rev 01)
Are there any other logs that I may provide that would be useful to
the community for this issue? Are there other items I should look at
besides NetworkManager as a cause? Any help is certainly appreciated.
ps. The wired network still functions flawlessly so I am not sure that
this has anything to do with NetworkManager at all.
Cheers!
