I have a Dell studio 1557 notebook which has a dell wireless card. I installed Ubuntu 13.04 but no wireless connection established. There was no problem with wired connection. Then I clicked additional drivers and it found something like Broadcom STA wireless driver so I downloaded. but there appeared an error message on install. so I dont have a wireless connection. How can i solve this and establish a wireless connection ? Thanx in advance
edit on demand: Network controller Broadcom Corporation BCM 4312 802.11 b/g LP-PHY (rev 01)
How can i install drivers for this card ?
