rtl8821ae constantly dropping signal

rtl8821ae constantly dropping signal

[Ed Ceaser]

Hi everyone,

I'm trying to get a Realtek 8821ae chip working, using the staged drivers 
in the kernel's Git repo.

Everything works fine up until the point where I actually connect to a 
secured 802.11n wireless network. At this point, I connect to the access 
point, but it repeatedly drops and reassociates every few seconds.

My access point's logs don't really say anything useful, but I pasted the 
driver's logs from one "cycle" at the end of this post.

I'd love to help out with debugging this, but I'm not really sure here 
where the actual drop out of the signal is occurring, so I don't really 
know where to start looking in the driver for issues. Any guidance would 
be appreciated.
