No eth0 and wlan0

Hey. So I just installed Arch (the core, anyway) on my Acer Aspire 5750. I tested my network connection by pinging Google and it failed. It turns out my eth0 and wlan0 interfaces are not recognised.

An ifconfig returns the information of my loopback interface, but not eth0 or wlan0, they're not there.

An lspci | grep -i net returns:

02:00.0 Ethernet controller: Broadcom Corporation Device 16b5 (rev 10)
03:00.0 Network controller: Atheros Communications Inc. Device 002e (rev 01)

So, does this mean the drivers for these devices are not installed? If so, how do I go about installing them?

I've had a look at the Arch Wiki and tried a couple of things but to no avail, anyone mind helping me out please?

Cheers.

Re: No eth0 and wlan0

You should already have both the necessary drivers with an Arch-core install:
- You need the tg3 driver for your Broadcom card; it's in-kernel since 2.6, so you should already have it.
- You need the ath9k driver for your Atheros card; also kernel-included.

What do you have in your /etc/rc.conf?

cat /etc/rc.conf

Does dmesg provide anything useful?

dmesg | grep -e 'net' -e 'firm' -e 'tg3'

Re: No eth0 and wlan0

Can you post the output of lspci -n and of ifconfig -a

Re: No eth0 and wlan0

You used the horribly outdated 2010.05 iso? If so the kernel might just be too old.

In this case try one of those http://releng.archlinux.org/isos/
They are not yet official and may not work at all, but you can give them a try. Some people used them to successfully install Arch when the old images didn't work.

This worked nicely, thanks.
