No network device availeble

[HungryDad]

I'm new to Linux and trying to reuse an old laptop and get better a Linux.

I've installed CentOS 6.8 and the network card was discovered and setup correctly.

I tried to install CentOS 7 but no network card are available.

Here is what i've tried so far:

ifconfig output :

lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>
loop txqueuelen 1 (Local Loopback)

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 496 bytes 42296 (41.3 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

lspci -nn | grep net output :

00:0a.0 Ethernet controller [0200]: NVIDIA Corporation MCP67 Ethernet [10de:054c] (rev a2)
03:00.0 Network controller [0280]: Broadcom Limited BCM4311 802.11b/g WLAN [14e4:4311] (rev 02)

uname -r output :

3.10.0-514.6.2.el7.x86_64

First question : How can i install the driver for the ethernet card?
Second would be for the WiFi card but one i'd settle for the Ethernet to begin with.

Thanks.

CentOS 7 deprecated almost all 100Mbps ethernet card support which is why your wired connection is not being seen. You can grab kmod-forcedeth from ELrepo and transfer it to your machine via a USB stick and then yum install it from there. That will get your wired connection working. The wifi one is more problematic I think as I seem to recall that the Broadcom 43xx chips have a driver that's licensed under some weird terms which means no-one can distribute it. ELRepo might have more details about that too.

Thanks for the answer.

There are many files begining with kmod-nvidia, 17 to be exact. Do i have to try each of them or is there a way to narrow my search?

[TrevorH]

Ooops, there was a typo in my original reply, since corrected. You don't want kmod-nvidia, you want kmod-forcedeth which is the driver for nvidia 100Mbps ethernet cards. I suspect there's only one of those.

I tried to install some and saw there were dependencies like nvidia-x11-drv or nvidia-x11-drv-340xx.

I'm not sure how to install them.

Thanks.

Ignore kmod-nvidia, it was wrong. Fingers in gear, brain disengaged, sorry.

[HungryDad]

TrevorH,

Thanks, that worked fine!

Sorry about your fingers!

I've learned some things today!

Happy Easter!
