@13718484207, that is so vague that it doesn't help those trying to help you. Did you see this in varunendra's post?...

If nothing comes up in the above output, and you are still unable to connect, please follow the "Wireless Script" link in my signature, download and run the script as per instructions there, and post back the report it generates.

Run the wireless script and then post the report. It will give the information people need to be able to help you. The BCM4313 wireless device should work out of the box in 13.10 with the default brcmsmac driver, so it's possible an attempt at installing one of the other Broadcom drivers is the problem here. Please also run this terminal command that varunendra posted...

grep -R brcm /etc/modprobe.d

... and post the output, whatever it says, even an error message if that is what you get.

[13718484207]

I have ran the script posted by varunendra, The output contains "blacklist brcmsmac" and "blacklist bcma",then I comment these lines in the conf file and reboot my computer, but I also can not connect to the wireless.
A few days ago,I can connect to the wireless, but when I update my kernel, I can not connect to the wireless.Now I will try the wireless scripts.
I am a freshman in ubuntu,thank you!

[varunendra]

Welcome to the forums !

Please also check if the native driver "brcmsmac" is blacklisted (probably by a faulty installation/removal attempt of the sta driver "wl") -

grep -R brcm /etc/modprobe.d

If you see lines like "blacklist brcmsmac" or "blacklist bcma" etc., either remove those files/entries, or post back the output here if unsure.

If nothing comes up in the above output, and you are still unable to connect, please follow the "Wireless Script" link in my signature, download and run the script as per instructions there, and post back the report it generates.

While posting the outputs, please use 'Code' tags. It preserves the output's formatting and makes the post cleaner, compact and more readable. To see a quick 'HowTo' with screenshots, please follow the "Using Code Tags" link in my signature.
