Can some one please comment on the issue I am facing Date: Fri, 15 Mar 2013 13:29:32 +0000 (UTC) Message-ID: (sfid-20130315_142955_822110_63E16693) Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: linux-wireless-owner@vger.kernel.org List-ID: Hello all, driver used : rtl8192cu When I tested with my linux kernel 3.0 , I didn't have any problems connecting to AP. But with kernel 3.6.8 , I had a problem . When I tested with 3.7.8 also I am facing the same problem. This is the latest kernel used by latest release of buildroot , so I didn't test any kernels after that version. The authentication and association are fine but from some reason it is disassociating after that and it keeps repeating it and it never connects to the AP.
