Dell Latitude E6410, No Network (At All)

Hello everyone. I just received a Dell Latitude E6410 laptop with a core i5 processor. When I took it out of the box, I used Clonezilla to save the factory image over the network to my server, and then I wiped the drive and installed Arch. Arch does not connect to the network at all, and I've never had this problem before. I know the network card works, because I used Clonezilla to save the image across the network.

Another strange thing is that it doesn't see my wireless card. I have an Atheros AR5B91 (which is a card I carried over from another laptop, to replace the one that this laptop came with) and this card is supported by the Linux kernel natively on every distro I tried, but Arch doesn't see it for some reason.

I'm assuming that I need the latest kernel since this is a very new chipset and processor, is it possible that I somehow need to update the kernel? The problem though is I cannot get on the network to do so. sad

That doesn't work either. Wired gets an IP address, but then cannot ping the router though it can ping localhost. Right now I'm confused how it can get an IP from my router but then fail to ping it.

Have you done anything to configure the network?  It won't just work on it's own.

I tried to do "ifconfig eth0 up" and that didn't work. I have installed Arch several times on several machines and never needed to do anything to get it to work. sad

What do you mean by it "didn't work"?  How are you getting an IP address?  Static?  DHCP?

This laptop uses DHCP. I don't have anything fancy, just a wired cable plugged into this laptop.

I just tried an Ubuntu live cd, and eth0 and wlan0 both work.

In Arch, eth0 gets an IP address. It cannot ping the router though, which is strange.

Is your computer using DHCP at boot to get an IP address, or do you do it manually?

If you're doing it manually, simply running

ifconfig eth0 up

will not get you an IP address via DHCP.  After putting the interface up, you still need to run

dhcpcd eth0

dhcpcd eth0

It says that DHCP is running already.

Here is the clincher. I put the hard drive in a different PC and it works fine. I updated it, and then put it back in this laptop, and I still have a problem. So my configuration is fine, it's something with this laptop. Strangely, it works with the Ubuntu live cd but I don't want to use that.

Edit: It's not getting an IP address now either. There is nothing listed for IP when I type in "ifconfig".

Edit 2: Now that I used it in another PC, it won't find the root device now unless I run under recovery mode.

Edit 3: I am having the same problem as this person (EXACTLY, right down to the card), but I don't understand what he did to solve it:

More info. I took the laptop to work and wired networking works perfect. I brought it back home, and it won't work. This is despite having two other desktops and another laptop that have no issues, and the laptop in question works fine with any other OS.

It seems like the person used an install CD that's more up-to-date, so that the drivers included in the kernel are newer.  How old is your install CD?  Have there been driver updates to your network cards since then?

The disc I'm using is the 2010-05 version, I believe that's the newest one. I downloaded all the updates while I was at work. I just find it so strange that it works fine at work, but not at home, and the same laptop works fine at home with an Ubuntu live CD.
