Hi,
As above I have a wifi connection that frequently drops out. Typically with the following, but instantly reconnects:
CFG80211-ERROR) wl_is_linkdown : Link down Reason : WLC_E_LINK
link down if wlan0 may call cfg80211_disconnected. event : 16, reason=1 from 18:83:bf:cb:66:21
CFG80211-ERROR) wl_is_linkdown : Link down Reason : WLC_E_LINK
CFG80211-ERROR) wl_notify_scan_status : scan is not ready
CFG80211-ERROR) wl_cfg80211_connect : Connecting with18:83:bf:cb:66:21 channel (6) ssid "BTHubIsABoxOfJunk", len (17)
wl_bss_connect_done succeeded with 18:83:bf:cb:66:21
wl_bss_connect_done succeeded with 18:83:bf:cb:66:21
Power saving is off. Once connected via wpa_supplicant etc, what keeps/monitors the connection state between the AP and my board? Is something exchanged on a frequent basis between the warp7/imx7 and AP? Or once connected does the connection wait forever silent for an AP disconnect like TCP or visa-versa?
Thanks,
Ed.
Hi Ed,
I have the same problem like you. Did you find the solution?
Thanks.
No, not yet. Bit difficult to find out exactly what communication goes on behind the scenes between the AP and the Warp7 regarding "connection" states or how it's maintained; and work diversions too...
Hi Edward,
Reason=1 means: "Unspecific Reason".(Linux WiFi Reason Codes - Disconnection & De-Authentication Issues ).
In my case, the problem was the AP.( faulty ).
Reason=1 is an "external" element that disconnects the Wi-Fi driver. (Access point, Dhclient, dhclient lease time..)
Hope that helps.
external" element that disconnects the Wi-Fi driver. (Access point, Dhclient, dhclient lease time..) very interesting, great bit of info. Thanks!
Hi Ed
what wifi module used in the case, if murata then this may be posted on murata support:
wireless.murata.com/eng/products/rf-modules-1/wi-fi-bluetooth-for-freescale-i-mx.html
seems this may be session timeout as described on https://communities.intel.com/thread/60095
Best regards
igor

Hi Igor,
Appreciate that, but I'm more interested in knowing what maintains an AP<=>Board connection once connected. Any answers to the below would be helpful.
1) Power saving is off. Once connected via wpa_supplicant etc, what keeps/monitors the connection state between the AP and my board?
2) Is something exchanged on a frequent basis between the warp7/imx7 and AP? Or once connected does the connection wait forever silent for an AP disconnect like TCP or visa-versa?
