Message-ID: <509200A2.9060300@mac.com> (raw)
Dear all,
I have a problem RTl8723 wifi connection. I can connect the access point
fine but exactly 10 seconds later, the connection will be lost. This is
100% reproducible. Here is the "iw event" log.

Does anyone have the same problem? Can someone tell me what is "wlan0:
unknown event 20"? I suspect this is the cause of the disconnection. I
am no wifi expert. Where should I take look at in the source code?
I am using Fedora 16 kernel 3.4.9 with some minor patches and Realktek
driver provided from my vendor,
"8723AE_linux_WiFimac80211_0007.0809.2012.tar.gz".
And here is lspci info.

I have sent the same question to the Realtek support but I also
appreciate your help.
