I recently upgraded to Ubuntu 13.04 from Ubuntu 12.10. However, since then although my wireless network is detected, I cannot connect to it.

Ubuntu keeps on trying to reconnect with the network but is not successful. Same machine on Windows 8 I am able to connect to the same wireless network.

Also, Ethernet is working fine as I am able to connect to the same network through Ethernet on Ubuntu.

My lspci -nn output is 

12:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless
LAN Controller [14e4:4727] (rev 01)
13:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.               
RTL8101E/RTL8102E PCI Express Fast Ethernet controller [10ec:8136] (rev 02)

I already tried the solution in this post Broadcom Corp. BCM4313 Wirelss not detected in Ubuntu 12.10 but it not solving my problem. The situation is the same.

Please help me. I do not want to switch to using Windows again.

Same here, I spent one hour trying recypes; then I stumbled into this which might be the easiest solution. Open software center and search "jockey-kde". Install it and reboot. This solved for me the wi-fi and video issues.

Optionally, open a terminal and: sudo apt-get install jockey-kde.

After having solved the problem on my XPS-L502X, I found that typing Dell on the software center brings up a package of drivers and an installer. Didn't try them tho.

Please let know if this helped.
