Issue with OS not recognizing NIC

Postby Sarnak » 2017/09/26 23:43:20

I have a 2009 HP Pavilion dv6-1235dx. Normally during installation, I would enable networking, but that option was not selectable this time. After installation, the networking files don't exist at all. My MAC address does not appear in ifconfig -a. Eth0 does not exist in dmesg. Using lspci, there is an entry for my network controller, which is listed as Broadcom Limited BCM4312 802.11b/g LP-PHY. I have done a search for that and found that I might need to install "firmware-b43-lpphy-installer_015-14.1_all.deb". I am not sure if that is correct, and I still have the issue that I cannot connect to the internet to do an apt-get. There is surely a way to do it using a USB, but I am not sure how, or if there are going to be a million other dependencies I will need to get as well.

Any help would be greatly appreciated!

Update: I tried installing CentOS 7 instead, and I am having the same issue with that. I think it has to be a driver issue. If anyone has any suggestions for me, I'd sure like to hear them though.

This is for your wireless connection right?

This is your wireless card and it's one that has a driver with licensing restrictions that means that the distro cannot ship the driver for it. There are ways to make it work using ELRepo but you have to build the drivers yourself as they also cannot redistribute the source.

However, according to Google that laptop ought to have a wired ethernet connection too and that might be easier to get working so that at least you have network access and that will make getting the wireless card working easier. Are there no other lines than that one in the output of lspci -nn | grep -i net ?
