Random wireless stalling using wl driver, chipset broadcom 4313 [14e4:4727], on a Lenovo S206

[matthew symes]

I am randomly losing connectivity to the Internet. I cannot ping anything, DNS resolving does not work and i cannot view any web pages, apt-get and such.

I am seeing this issue on the liveCD, a fresh install of Saucy (daily build 23/5/2013) and also on an upgrade from Raring to Saucy.

Network manager still thinks i am connected.

I have disabled network manager and connected using a wpa_passphrase file and i still get the same issue.

Interestingly enough, if i disconnect and reconnect to the wireless access point using nm_applet, i can get connectivity again until it stops again.

route and arp -a were taking an age to return so i added a static entry to the arp cache. That made no difference.

I have increased the debugging level from wpa_supplicant but i could not see any obvious failure in there. I'm not 100% sure what to look for though.

I could see nothing in syslog or dmesg that would point to any obvious failure.

I have uploaded this bug report after booting into the fresh problem install, waiting for the connection problem, reconnecting and raising this bug report.

I am willing to help with any diagnostic information i can supply. The only connectivity this netbook has is wireless so this will be an issue when Saucy is released.

I have lost connectivity while typing up this bug report.

 I should say nm_applet still shows i'm connected.

Also i have raised this bug against network-manager but i'm not sure if the problem is there, or with the driver, wpa_supplicant etc
