Hello,
I'm trying to get access to a WLAN access point using the following adapter:
<http://www.edimax.com/edimax/merchandise/merchandise_detail/data/edimax/global/wireless_adapters_n150/ew-7811un>
I've used "NetworkManager" to connect to the access point and everything
seemed to work well at first.
But after a few minutes the connection is lost with the following
message in dmesg:
wlan0: disassociated from XX:XX:XX:XX:XX:XX (Reason: 2)
If I restart NetworkManager, then the connection works again, but only
for a few minutes before I get another disconnect.
I even tried to do a permanent ping to a server on the Internet (to have
permanent traffic) but this doesn't change anything. I still get
disconnected with "Reason 2".
Are there known problems with the rtl8192cu driver?
Can someone here recommend a small USB WLAN adapter which is known to
work without problems?
Thank you very much in advance.
Greetings
Manuel

Thank you very much for this feedback.
Searching for 'rtl8192cu "Reason 2"' on the net reveals more cases for
such problems. For example:
https://dev.openwrt.org/ticket/15342
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1220007
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=661860
So in other words: Seems like rtl8192cu driver is broken.
And as I am unable to fix it, I'll have to try to find a WLAN interface
with better Linux support.

What exactly is "b/g"?

I had a similar problem with this driver. After a while, the aggregation
session seems to hang. If I connect as b/g, no problem. If I disable
aggregation by patching the driver, again the problem goes away.
That's as far as I got.

I was referring to the 802.11b and 802.11g IEEE lan standards.
