Link quality is "0/100" but it's Associated.<br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">If so, please try these two steps:

I thought to specify my WEP key and with the WEP key also no luck. It get's associated with the AP but link quality is 0. LED also doesn't work. Note this time my network manager is running.
