Bug description:
Hi,
attaching a Edimax EW-7612UAn V2 802.11n Wireless Adapter [Realtek
RTL8192CU] on the machines usb port and connecting to a wifi spot
seems to work fine. The system seems to have a physical connection to
the other end (connection manager shows successfully established link
with aquired ip/subnet, link speed and loaded driver) but no data will
be transfered over the device. Having a closer look at the kernel
messages, i found this:
