This question already has an answer here:
I just upgraded to 13.04 from 12.10 and discovered I was unable to connect to my home wireless network even though I can detect the network (and neighboring networks). However, I was able to connect via an ethernet cable to the router.
I noticed quite a few people were having similar issues and was wondering if anybody had reached a breakthrough. I tried disabling and re-enabling the wireless card, rebooting the computer, and rebooting the router all to no avail.
Some miscellaneous facts:
- I am running a Broadcom 4313 wireless card and my computer is a Dell N5010.
- My region is USA.
- When I upgraded to 12.10, I had to reinstall the driver set for bcmwl.
