I have a laptop with an Intel Corporation Centrino Wireless-N 1030 wifi adapter. (Network controller: Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak] (rev 34))
This adapter worked fine until there was an upgrade to wpa_suppliant 2.x. After that many 'nl80211: send_and_recv->nl_recvmsgs failed: -33' messages are found in the log and the wifi connection is down for about 15 seconds. This happens every 2 minutes. Feb 23 17:40:14 notebook wpa_supplicant[1117]: nl80211: send_and_recv->nl_recvmsgs failed: -33 This makes the jessie for this kind of laptops almost unusable. I have tried the suggestion 'modprobe iwlwifi 11n-disable=1' 2, 4 or 8. But then can cannot connect at all to my AP. So I think there is a major problem for the Jessie iwlwifi users. I hope for a fast solution ;) /Willem
