Hi all. I have a variant of this common problem.
My wifi is up and down like a ***** ********. All updates are in place and I have gone through my friend Goole at length and tried a few things it suggested. The wifi disconnects regularly, which is not good for a wireless server!
The following is just one example of many entries to syslog:
My wireless-info file shows the following (looks like it was in disconnected mode when I ran the script - as it spends more time disconnected than connected, this is not a surprise):Code:May 24 14:51:25 #SERVER# kernel: [ 1008.040323] cfg80211: Calling CRDA to update world regulatory domain May 24 14:51:25 #SERVER# wpa_supplicant[1588]: wlan0: CTRL-EVENT-DISCONNECTED bssid=nn:nn:a5:a2:de:95 reason=4 locally_generated=1 May 24 14:51:25 #SERVER# kernel: [ 1008.103177] cfg80211: World regulatory domain updated: May 24 14:51:25 #SERVER# kernel: [ 1008.103184] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) May 24 14:51:25 #SERVER# kernel: [ 1008.103199] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) May 24 14:51:25 #SERVER# kernel: [ 1008.103209] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) May 24 14:51:25 #SERVER# kernel: [ 1008.103218] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) May 24 14:51:25 #SERVER# kernel: [ 1008.103226] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) May 24 14:51:25 #SERVER# kernel: [ 1008.103235] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) May 24 14:51:25 #SERVER# wpa_supplicant[1588]: wlan0: CTRL-EVENT-SCAN-STARTED May 24 14:51:26 #SERVER# wpa_supplicant[1588]: wlan0: SME: Trying to authenticate with nn:nn:a5:a2:de:95 (SSID='#HIDDEN#' freq=2437 MHz) May 24 14:51:27 #SERVER# kernel: [ 1009.556403] wlan0: authenticate with nn:nn:a5:a2:de:95 May 24 14:51:27 #SERVER# kernel: [ 1009.562125] wlan0: send auth to nn:nn:a5:a2:de:95 (try 1/3) May 24 14:51:27 #SERVER# kernel: [ 1009.637329] wlan0: send auth to nn:nn:a5:a2:de:95 (try 2/3) May 24 14:51:27 #SERVER# kernel: [ 1009.648626] wlan0: send auth to nn:nn:a5:a2:de:95 (try 3/3) May 24 14:51:27 #SERVER# wpa_supplicant[1588]: wlan0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="#HIDDEN#" auth_failures=1 duration=10 May 24 14:51:27 #SERVER# kernel: [ 1009.704705] wlan0: authentication with nn:nn:a5:a2:de:95 timed out May 24 14:51:32 #SERVER# wpa_supplicant[1588]: wlan0: CTRL-EVENT-SCAN-STARTED May 24 14:52:29 #SERVER# wpa_supplicant[1588]: message repeated 9 times: [ wlan0: CTRL-EVENT-SCAN-STARTED ] May 24 14:52:31 #SERVER# wpa_supplicant[1588]: wlan0: CTRL-EVENT-SSID-REENABLED id=0 ssid="#HIDDEN#" May 24 14:52:31 #SERVER# wpa_supplicant[1588]: wlan0: SME: Trying to authenticate with nn:nn:a5:a2:de:95 (SSID='#HIDDEN#' freq=2437 MHz) May 24 14:52:31 #SERVER# kernel: [ 1073.644919] wlan0: authenticate with nn:nn:a5:a2:de:95 May 24 14:52:31 #SERVER# kernel: [ 1073.653101] wlan0: send auth to nn:nn:a5:a2:de:95 (try 1/3) May 24 14:52:31 #SERVER# wpa_supplicant[1588]: wlan0: Trying to associate with nn:nn:a5:a2:de:95 (SSID='#HIDDEN#' freq=2437 MHz) May 24 14:52:31 #SERVER# kernel: [ 1073.711644] wlan0: authenticated May 24 14:52:31 #SERVER# kernel: [ 1073.716426] wlan0: associate with nn:nn:a5:a2:de:95 (try 1/3) May 24 14:52:31 #SERVER# kernel: [ 1073.772007] wlan0: associate with nn:nn:a5:a2:de:95 (try 2/3) May 24 14:52:31 #SERVER# kernel: [ 1073.816703] wlan0: associate with nn:nn:a5:a2:de:95 (try 3/3) May 24 14:52:31 #SERVER# wpa_supplicant[1588]: wlan0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="#HIDDEN#" auth_failures=2 duration=20 May 24 14:52:31 #SERVER# kernel: [ 1073.845040] wlan0: association with nn:nn:a5:a2:de:95 timed out May 24 14:52:41 #SERVER# wpa_supplicant[1588]: wlan0: CTRL-EVENT-SCAN-STARTED May 24 14:52:53 #SERVER# wpa_supplicant[1588]: message repeated 2 times: [ wlan0: CTRL-EVENT-SCAN-STARTED ] May 24 14:52:55 #SERVER# wpa_supplicant[1588]: wlan0: CTRL-EVENT-SSID-REENABLED id=0 ssid="#HIDDEN#" May 24 14:52:55 #SERVER# wpa_supplicant[1588]: wlan0: SME: Trying to authenticate with nn:nn:a5:a2:de:95 (SSID='#HIDDEN#' freq=2437 MHz) May 24 14:52:55 #SERVER# wpa_supplicant[1588]: wlan0: Trying to associate with nn:nn:a5:a2:de:95 (SSID='#HIDDEN#' freq=2437 MHz) May 24 14:52:55 #SERVER# kernel: [ 1097.924986] wlan0: authenticate with nn:nn:a5:a2:de:95 May 24 14:52:55 #SERVER# kernel: [ 1097.938028] wlan0: send auth to nn:nn:a5:a2:de:95 (try 1/3) May 24 14:52:55 #SERVER# kernel: [ 1097.939799] wlan0: authenticated May 24 14:52:55 #SERVER# kernel: [ 1097.944245] wlan0: associate with nn:nn:a5:a2:de:95 (try 1/3) May 24 14:52:55 #SERVER# wpa_supplicant[1588]: wlan0: Associated with nn:nn:a5:a2:de:95 May 24 14:52:55 #SERVER# kernel: [ 1097.989240] wlan0: RX AssocResp from nn:nn:a5:a2:de:95 (capab=0x11 status=0 aid=3) May 24 14:52:55 #SERVER# kernel: [ 1097.991039] wlan0: associated May 24 14:52:55 #SERVER# wpa_supplicant[1588]: wlan0: WPA: Key negotiation completed with nn:nn:a5:a2:de:95 [PTK=CCMP GTK=TKIP] May 24 14:52:55 #SERVER# wpa_supplicant[1588]: wlan0: CTRL-EVENT-CONNECTED - Connection to nn:nn:a5:a2:de:95 completed [id=0 id_str=]
