Ah, good point. Can you post your wpa_supplicant.conf (without the commented lines) here? wpa_supplicant's default configuration scans periodically for new networks. If you are only using it for mesh, this is not needed and can be disabled with ap_scan=0 Alternatively, to rule out wpa_supplicant issues, you can try the simpler authsae daemon: https://github.com/cozybit/authsae Cheers, Javier > On Thu, Apr 14, 2011 at 12:06 PM, Javier Cardona <jav...@cozybit.com> wrote: >> >> Hi Zaki, >> >> On Tue, Apr 12, 2011 at 11:29 PM, Zaki <zaki...@gmail.com> wrote: >> > We are actively doing testings with Open and SAE Mesh.
