wifi adapter problem

[David Ronkin]

Hi

I bought Edimax  EW-7711USN usb adapter (with linux support written on the
box).
Looks like the driver is found by my ubuntu 10.10 Maverick (on titan laptop)
but still i cannot go to web (i have open wireless nw around) - getting the
error below.

I googled for some time but gave up meanwhile,
Please kindly help!

Here some logs:
