Trouble with wireless

Axalon · 2012-02-15 05:19:45

I installed Arch on my laptop a bit ago and am having no luck with enabling wireless. I read through the Wireless setup page on the wiki but I can't find my card, a Realtek RTL 8101E/8102E. I've followed the instructions on the Network Manager page but that doesn't work, I tried newlan but it also failed me. I have wpa_supplicant and wireless_tools installed. Being a complete novice at network management I'm pretty lost at the moment and am not even sure what else to try next, so any help would be greatly appreciated.

Can you post the output of:
ip link
lspci -nn (That is two n's, not m)

Okay, and now the output of :
lsmod | grep r8

Axalon · 2012-02-15 06:23:01

r8169                  49040  0 
mii                     4059  1 r8169

I don't have your card, but I think you have the wrong kernel module. I think it is supposed to be the r8101 driver.

Try this (as root):
rmmod -f r8169
If that does not crash your system, then do a (again, as root)
modprobe r8101

And see if your wireless appears. You can check that with the ip link command.

Try those, and let's decide what to do next.

Well rmmod -f r8169 just disables internet connectivity altogether and modprobe r8101 does comes up with the error "Module r8101 not found".

Sorry about that

I thought it was a module included with the kernel. Apparently not. Can you install aur/r8101 (Note that it is in the AUR).

Of course, you'll probably need to modprobe r8169 and use the wired connection to do that

Axalon · 2012-02-15 06:49:03

Ha, I'm not having any luck tonight.. Everytime I try to build it I get "ERROR: A failure occurred in build()." Unfortunately no other information is given so I can't even begin to figure out why it failed.

ewaller · 2012-02-15 07:05:06

Okay, sanity check time. Any chance you have updated your kernel, but have not rebooted as of yet?
check your kernel with uname -a
Make sure it matches what is in ls /lib/modules
You may also need to have linux-headers installed to do the build.

If you have a new kernel that you've not yet started, it might work after a reboot with the r8169.

Edit: I'm on the West coast of the United States. I need to call it a night. I'll pick this up in the morning

Well I didn't have the headers installed but they didn't help. This is unclear to me but perhaps it'll be a bit more revealing to you.

Thanks for attempting to help so far. Arch is absolutely perfect on my desktop but I'm having a hell of a time with it on my laptop.
