Created attachment 72907 [details] /var/log/syslog of linux 3.4-rc4 Hardware: Samsung SF510 (shark) laptop Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01) I'm using the brcmsmac module. I can see various access points in network-manager, including my home network, "Basel". When trying to connect to "Basel", however, it doesn't work. My interpretation of /var/log/syslog tells me that the failure is probably be caused by the brcmsmac driver that for some reason is not sending/receiving any packets to/from the access point. Any suggestions about how to further track this down this most welcome! I am currently testing this with linux 3.4-rc2. I have tested 3.3.2 previously and it had the same problem. Linux 3.2.14 does not have have the problem. The driver works fine there.
Other, probably related bug reports: http://comments.gmane.org/gmane.linux.kernel/1272203 https://bugzilla.kernel.org/show_bug.cgi?id=42686 (sorry, found that only now, could be an exact duplicate) https://bbs.archlinux.org/viewtopic.php?pid=1074977#p1074977
bug 42686 is about iwlagn device so it would only be a duplicate when it is a mac80211 issue. From the log it shows dhcp is failing. 9 out of 10 times that means packets are not properly encrypted. wireless sniff or some logging info from your AP would help to determine that.
Hello, thanks for following up on this bug. I'm sorry to say that it seems to be non-reproducible at the moment. Let's "suspend" it. The last 2 times I bootet into 2.4-rc2, the wireless network got actually connectet normally. The first time, there was a strange lang between Step 4 and 5 of about a minute... ?? But otherwise everything worked fine. Maybe the device (*cough*) just had to (*cough* ehr...) got used to the new driver. - No - seriously - I don't know what might have been the problem here, but let's suspend it. Sorry for the noise.
