After upgrading to Ubuntu 13.10 I keep getting connection timed out every few seconds at which point i have to disconnect and reconnect to the WiFi network.

The WiFi card worked fine on 13.04 with the bcmwl-kernel-source installed but giving problems on 13.10:

*-network               
       description: Wireless interface
       product: BCM4313 802.11bgn Wireless Network Adapter
       vendor: Broadcom Corporation
       physical id: 0
       bus info: pci@0000:02:00.0
       logical name: eth1
       version: 01
       serial: c0:14:3d:cc:c9:c7
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless 
       configuration: broadcast=yes driver=wl0 driverversion=6.30.223.141 (r415941) ip=192.168.1.4 latency=0 multicast=yes wireless=IEEE 802.11abg 
       resources: irq:17 memory:f0500000-f0503fff

How can i fix this?

Thanks

  • Thank you for the response. However i got error wl module not found. continued with the steps but after reboot wifi could only find one network (not my own) – Wahtever Nov 07 '13 at 17:31
  • Copy and paste this command in the terminal (ctrl+alt+t)wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script It will download a script and create a file named wireless-info.tar.gz in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security,paste contents of the wireless-info.tar.gz file as a zip file at http://pastebin.com/.

  • Here it is pastebin – Wahtever Nov 07 '13 at 17:50
  • I added a command you need to run then reboot. – Wild Man Nov 07 '13 at 17:58
  • Still not showing any wifi networks – Wahtever Nov 07 '13 at 18:06
  • Run the script again and post the new file to pastebin so we can see the changes. – Wild Man Nov 07 '13 at 19:18
  • Here is the second one pasebin – Wahtever Nov 07 '13 at 20:04
  • Please do sudo modprobe -v brcmsmac does it come alive? – Wild Man Nov 07 '13 at 20:52
  • Nothing happens when i run it – Wahtever Nov 07 '13 at 20:56
  • Remove all wireless networks from network manager then reset your router and reboot computer. – Wild Man Nov 07 '13 at 21:04
  • Removed all the networks, rested the router, did a reboot didn't work. Then reran sudo modprobe -v brcmsmac. Still can't find any networks listed – Wahtever Nov 07 '13 at 21:16
  • There is a bug in this version of brcmsmac hopefully this will work since b43 is blacklisted, we may have to blacklist brcmsmac also. I change my answer. – Wild Man Nov 07 '13 at 21:32
  • Wifi works now. However the original problem returned. – Wahtever Nov 08 '13 at 08:28
  • Please do not post duplicate answers on different questions. It just creates more work for the moderators. If the questions are so similar that the same answer works on each, then the later of the two is likely a duplicate and should be flagged as such. – RolandiXor Nov 08 '13 at 17:27
