Created attachment 577444 [details] dmesg output It's awesome that my wifi card works out of the box. Till fedora 16, I needed to install the kmods from RPMFusion. [root@ankur ~]# lspci | egrep -i network 12:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) [root@ankur ~]# However, wireless is very slow. I'm sitting right next to my router. Byobu shows the wireless strenght as 100% too. While on LAN, I get the full 2mbps speed, on wifi I get only around 200kbps. There seem to be quite a few errors related to ieee80211 in dmesg too (attached). I'd like to help resolving this issue. Please let me know if you need any additional info. Thanks, Ankur
Someone suggested I try to switch off power saving on the device: [root@ankur ~]# iwconfig wlan0 power off Error for wireless request "Set Power Management" (8B2C) : SET failed on device wlan0 ; Operation not supported. [root@ankur ~]# I tried to use powertop too, but cannot do it. Is powersaving mode the reason behind the slow speeds? Thanks, Ankur
As the error message is showing you powersaving is not available. powersaving is not the problem here. I do see indeed a lot of these messages: [ 75.536457] ieee80211 phy0: brcms_c_prec_enq_head: No where to go, prec == 4 This indicates that the transmit queues in the driver have reached their limit. I noticed that you are using regulatory domain IN (India?). Could you tell me what channel your AP is on?

Could you tell me > what channel your AP is on? Uhm, I'm not that advanced a user. Can you please tell me what commands you want me to run? I'll get back to you with the outputs. Yes. I am in India. I was using the kmod packages that rpmfusion provides for Fedora 16 and this issue didn't crop up. They package up the linux sta driver: [root@ankur ~]# repoquery -i kmod-wl Name : kmod-wl Version : 5.100.82.112 Release : 2.fc17.2 Architecture: x86_64 Size : 0 Packager : <http://nonfree.rpmfusion.org/> Group : System Environment/Kernel URL : http://www.broadcom.com/support/802.11/linux_sta.php Repository : rpmfusion-nonfree-updates-testing Summary : Metapackage which tracks in wl kernel module for newest kernel Source : wl-kmod-5.100.82.112-2.fc17.2.src.rpm Description : This is a meta-package without payload which sole purpose is to require the wl kernel module(s) for the newest kernel. to make sure you get it together with a new kernel.

Ankur You are not using the wl driver for your wireless. The log I looked at shows that brcmsmac is used. The information you sent me shows channels 1 to 13 are available. I assume your AP is on channel 6. You can confirm by calling iwconfig when the link is up.

Hi Arend, With the latest kernel update, wireless doesn't work anymore. I've filed a separate bug for the issue: https://bugzilla.redhat.com/show_bug.cgi?id=815059 I'm unsure of what's happening. Are there multiple drivers supporting my wireless hardware, since it worked initially? I'll boot into the older kernel (where wireless worked) and give you the output of iwconfig once I get back to my system in the evening. Thanks, Ankur
Could you also run following command ´lspci -v' on both kernels?
Ah. My wireless does work with brcmsmac as well. Works with kernel-3.3.2-8.fc17.x86_64 as well. The only thing I have to do is disable then re-enable wireless in NetworkManager for wlan0 to show up. I think this is a NwtworkManager bug because iwconfig shows wlan0 when NetworkManager is not seeing it.

I'm seeing something very similar with the BCM4313 in my new Lenovo U410. NetworkManager is only shows only a few of the available networks if any, most attempts to assoiate timeout. If a connection does complete then it will be very very slow before dropping. This is all using the 3.4.4-3 x86_64 kernel using the included brcmsmac driver. I saw mention of the 3.3.2-8 kernel here, but I've not been able to find it in the repos to give it a try. Can anybody point me at some where I can grab a copy for a test. Also please let me know if you need me any logs or more details capturing as this is the last thing holding me back using my sweet new machine. Ben
Is this still an issue with the 3.6.9 kernels?
I'm sorry I couldn't reply to the needinfo. I've been on vacation the last month. Any way, I think it's been fixed since I do get good download speeds now, unlike when I reported the bug. Thanks! I'll file more bugs if I run into other issues. Apologies, Thanks, Warm regards, Ankur
