How do I connect my NetXtreme BCM5755M Gigabit Ethernet PCI Express in y Dell latitude d630?

Question

Trying to get my 09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5755M Gigabit Ethernet PCI Express (rev 02) working with my wifi. I just installed Raring Ringtail on this dell latitude D630 and I can't get it to connect without a wifi dongle.

This is what I got when I typed sudo lshw -c network:

Also, when I go to additional drivers in the software and updates settings, no proprietary drivers show up.

I've tried sudo apt-get install b43-fwcutter firmware-b43-installer because it worked on a bunch of old Dell laptops that I converted over before, but it didn't work on this one. Is this driver even compatible with wifi?

Please help.

Answer 1

Last week, I installed a Broadcom BCM5755M WLAN card onto my Dell Latitude D630, along with a 320 Gb hard drive and the 64-bit version of Trusty. I don't remember having to reinstall the b43 drivers, but I am able to connect to wireless networks. I would like to figure out how to get wireless-N download speeds, though.

Answer 2

The BCM5755M is the wired ethernet controller, not the wireless one. The only way you'll get it to work is to plug in an ethernet cable.

The WiFi controller in a D620 or D630 is on a daughterboard, and can come several manufacturers. Hopefully you have the Intel one, which shows in lspci as:

0c:00.00 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
