Hi,
a new Thinkpad Yoga 20CD00AMGE with Intel(R) Dual Band Wireless AC 7260
fails to connect to the AP in the office, while it works
on my home AP. WPA2 is used in both cases. I tried with
kernel 3.14.7 and 3.15. There is a high density of APs and
clients and lots of traffic in the office environment.
The failure is caused by:
[ 32.200142] iwlwifi 0000:04:00.0: No association and the time event is over already...
and wpa_supplicant retries in an endless loop:
[ 28.181020] cfg80211: Calling CRDA to update world regulatory domain
[ 31.890168] wlp4s0: authenticate with f8:d1:11:39:1a:8c

[ 32.270241] cfg80211: Calling CRDA to update world regulatory domain
(repeats)
For testing I used a bare Arch Linux installation and ran
wpa_supplicant manually:
echo 'network={
ssid="foo"
psk="bar"
}' >w
wpa_supplicant -Dnl80211 -iwlp4s0 -cw -d
...

...

...
wlp4s0: CTRL-EVENT-CONNECTED - Connection to f8:d1:11:39:1a:8c completed [id=0 id_str=]
...
nl80211: Drv Event 20 (NL80211_CMD_DEL_STATION) received for wlp4s0
nl80211: Delete station f8:d1:11:39:1a:8c

nl80211: Deauthenticate event
wlp4s0: Event DEAUTH (12) received
wlp4s0: Deauthentication notification
wlp4s0: * reason 4 (locally generated)
wlp4s0: * address f8:d1:11:39:1a:8c
Deauthentication frame IE(s) - hexdump(len=0): [NULL]
wlp4s0: CTRL-EVENT-DISCONNECTED bssid=f8:d1:11:39:1a:8c reason=4 locally_generated=1
wlp4s0: Auto connect enabled: try to reconnect (wps=0 wpa_state=9)
Not really knowing what I'm doing I simply tried to comment out
the check causing the disconnect:
drivers/net/wireless/iwlwifi/mvm/time-event.c:iwl_mvm_te_handle_notif()
iwl_mvm_te_check_disconnect(mvm, te_data->vif,
"No association and the time event is over already...");
And lo and behold, it can connect.
Let me know if you need more information to produce a proper fix.
TIA,
Johannes

I have confirmation someone on the other side of the globe with
a similar machine sees the same issue.
