It seems the failure is due to the BANDWIDTH information mismatch in firmware when the initial connection is made with narrower PHYMODE and BANDWIDTH and then AP changed that later. I've seen similar issue earlier but I can't reproduce at my setup. I've sent out a patch to address that, to reconfigure the PHYMODE while changing the BANDWIDTH. Can you help to give it test to see if that helps at your end? -- Ryan Hsu _______________________________________________ ath10k mailing list [email protected] http://lists.infradead.org/mailman/listinfo/ath10k
