Package: src:linux
Version: 4.0.2-1
Severity: normal
Hello,
I noticed an issue with my usb WiFi thumb thingy not returning any
networks in scan. After many tries I found that it sometime returns an 802.11b
(1mbps+) AP but never returns the newer 6mbps+ APs
It turns out that the wifi is an rtl8192cu and
1) this does not happen with zd1211rw
2) this does not happen on the first time the WiFi thumb is plugged in
but happens any subsequent time
3) is fixed by unloading rtl8192cu (which is subsequently loaded by
plugging in the device or by hand)
I have no idea if this happens with Linux 4.1/master/whatever.
I might be able to test some more recent kernel version later.
Thanks
Michal
