Machine: HP dm1-4010us Broadcom 4313 [14e4:4727] with integrated Broadcom 20702 Bluetooth Software: Default installation of Fedora 16 "$uname -r": 3.1.7-1.fc16.x86_64 Summary of symptoms: After initial installation of Fedora 16 with updates to kernel 3.1.7, network manager shows a functional brcm4313 with wireless networks within range. However, all networks have 1 - 2 bars of signal, and connection to networks may take up to 30+seconds when standing within 3 ft of the router or not at all over 10ft distant without an obstruction. Connections that are established have frequent time-outs when browsing the internet, disconnections from the router with inability to re-establish a connection. This behaviour occurs in both WPA encrypted and unencrypted networks. What I've tried: I started with the FAQ check list on linuxwireless.org, below is output I encountered from each of the steps: First, this is the output from $dmesg with the Fedora 16 x86_64 kernel 3.1.7-1 version of ieee80211, brcmsmac, cfg80211, wlan0 outputs (This one is not from immediately after login): $dmesg [ 5546.472374] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: false (implement) [ 5546.472399] ieee80211 phy0: brcmsmac: brcms_ops_bss_info_changed: disassociated [ 5546.472413] ieee80211 phy0: brcms_ops_bss_info_changed: arp filtering: enabled false, count 1 (implement) [ 5546.472428] wlan0: deauthenticating from 26:4e:7f:40:9b:76 by local choice (reason=3) [ 5546.478142] cfg80211: Calling CRDA to update world regulatory domain [ 5546.509539] cfg80211: World regulatory domain updated: [ 5546.509547] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 5546.509553] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 5546.509557] cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 5546.509561] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 5546.509565] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 5546.509569] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 5546.509592] cfg80211: Calling CRDA for country: US [ 5546.520696] cfg80211: Regulatory domain changed to country: US [ 5546.520703] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 5546.520708] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2700 mBm) [ 5546.520713] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 1700 mBm) [ 5546.520717] cfg80211: (5250000 KHz - 5330000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 5546.520721] cfg80211: (5490000 KHz - 5600000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 5546.520725] cfg80211: (5650000 KHz - 5710000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 5546.520729] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 3000 mBm) [ 5567.191248] ieee80211 phy0: brcms_ops_config: change monitor mode: false (implement) [ 5567.191260] ieee80211 phy0: brcms_ops_config: change power-save mode: false (implement) [ 5567.192256] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: false (implement) [ 5567.193273] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 5616.345041] wlan0: authenticate with 20:4e:7f:40:9b:76 (try 1) [ 5616.346922] wlan0: authenticated [ 5616.347976] wlan0: associate with 20:4e:7f:40:9b:76 (try 1) [ 5616.356245] wlan0: RX AssocResp from 20:4e:7f:40:9b:76 (capab=0x431 status=0 aid=3) [ 5616.356255] wlan0: associated [ 5616.356812] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: true (implement) [ 5616.356826] ieee80211 phy0: brcmsmac: brcms_ops_bss_info_changed: associated [ 5616.356833] ieee80211 phy0: changing basic rates failed: -22 [ 5616.356839] ieee80211 phy0: brcms_ops_bss_info_changed: arp filtering: enabled true, count 0 (implement) [ 5616.357800] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready [ 5616.392720] ieee80211 phy0: brcms_c_dotxstatus: INTERMEDIATE but not AMPDU [ 5627.010110] wlan0: no IPv6 routers present [ 5637.003395] ieee80211 phy0: brcms_ops_bss_info_changed: arp filtering: enabled true, count 1 (implement) I have tried googling for "wlan0: deauthenticating from 26:4e:7f:40:9b:76 by local choice (reason=3)" and "ieee80211 phy0: changing basic rates failed: -22" but I was not able to find information I could understand how to use.

I used "$ ./scripts/driver-select brcm80211" to pick the drivers to compile.

I then tried to use iw to connect to an unencrypted wireless network in order to bypass Network Manager. I did this by first turning off wireless networking in the nm-applet and then turning it back on without having it join a network. I found when i felt wireless "off" in the nm-applet it gave a soft block in rfkill. I used "$ sudo iw wlan0 connect $SSID" which reported "wlan0 (phy #0): connected to $BSSID". However, when I followed with "$ sudo iw wlan0 link" it reported "Not Connected". dmesg after this transaction shows: [ 817.823171] ieee80211 phy0: brcms_ops_config: change monitor mode: false (implement) [ 817.823182] ieee80211 phy0: brcms_ops_config: change power-save mode: false (implement) [ 817.824322] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: false (implement) [ 817.825483] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 839.430644] wlan0: authenticate with 26:4e:7f:40:9b:76 (try 1) [ 839.432229] wlan0: authenticated [ 839.432365] wlan0: associate with 26:4e:7f:40:9b:76 (try 1) [ 839.438215] wlan0: RX AssocResp from 26:4e:7f:40:9b:76 (capab=0x421 status=0 aid=1) [ 839.438230] wlan0: associated [ 839.438757] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: true (implement) [ 839.438781] ieee80211 phy0: brcmsmac: brcms_ops_bss_info_changed: associated [ 839.438795] ieee80211 phy0: changing basic rates failed: -22 [ 839.438806] ieee80211 phy0: brcms_ops_bss_info_changed: arp filtering: enabled true, count 0 (implement) [ 839.440633] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready [ 839.440828] wlan0: disassociating from 26:4e:7f:40:9b:76 by local choice (reason=3) [ 839.441666] ieee80211 phy0: brcms_ops_bss_info_changed: qos enabled: false (implement) [ 839.441687] ieee80211 phy0: brcmsmac: brcms_ops_bss_info_changed: disassociated [ 839.441700] ieee80211 phy0: brcms_ops_bss_info_changed: arp filtering: enabled false, count 0 (implement) [ 839.441739] wlan0: deauthenticating from 26:4e:7f:40:9b:76 by local choice (reason=3) [ 839.448270] cfg80211: Calling CRDA to update world regulatory domain [ 839.460877] cfg80211: World regulatory domain updated: [ 839.460885] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 839.460890] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 839.460895] cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 839.460899] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 839.460903] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 839.460907] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 839.460940] cfg80211: Calling CRDA for country: US [ 839.468440] cfg80211: Regulatory domain changed to country: US [ 839.468446] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 839.468451] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2700 mBm) [ 839.468455] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 1700 mBm) [ 839.468459] cfg80211: (5250000 KHz - 5330000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 839.468463] cfg80211: (5490000 KHz - 5600000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 839.468467] cfg80211: (5650000 KHz - 5710000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 839.468471] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 3000 mBm) [ 850.002117] wlan0: no IPv6 routers present I never was able to get "$ sudo iw wlan0 link" to show I had a connection. I then proceeded to try the "bleeding-edge" compat-wireless driver from today's build. However, after the same steps as with stable compat-wireless, rebooting the newest build left me with non recognized wireless card. So I've reverted back to the stable compat-wireless version, that still has the symptoms summarized above. At this point I'm unsure where I may have went wrong or how to further proceed. But I am very willing to run any further tests needed to clarify the issue I'm having. Thank you for taking to time to read this. -Vince PS: I will be at work and away from the affected machine from Sunday 6am US Central Time until Monday 10am US Central Time. I realize this is a pretty fast moving mailing list and will try to answer any questions tomorrow in a timely fashion, but won't be able to do any tests until Monday morning.
