A caper of missing eth0, wireless issues, and missing tools

Ansikt · 2010-11-15 02:57:14

Hello all!

I'm a recent Arch convert from Xubuntu, and I've had some troubles installing it on my Gateway NV79. The first problem was that of going to black screen. This issue I remedied by entering "i915.modeset=0" at the end of the kernel line. This allowed me to boot into the live environment, and it installed correctly, but several things are amiss. Firstly, in the package group selection menu, I only get "base" and "base-devel," (I'm installing from a core image on CD, by the way) and while this isn't nessicarily an error, the Beginner's Guide and Installation Guide both imply that there would be more selection. I also cannot find my eth0. According to the Configuring Network wiki page, I need to issue "hwdetect --show-net," in order to find out which module works with my ethernet card (lspci tells me it's a Broadcom Netlink BCM57780) but am told that I have no hwdetect, either in live or installed environs. I also cannot get wifi to work, using either of the methods outlined in the wiki page for wpa_supplicant.

Any suggestions? Any command output or config files I should copy-paste?

ninja edit: OH, and I wasn't sure whether or not I should put this in the Newbie Corner, or Laptops forums. If I've done wrong, could a mod please move this? Sorry for the inconvenience.

Hello

That's a lot of issues you have here ^^

First, the core CD, as its name suggests, only contains the core packages. You need an internet connexion to get the other packages. No surprise here

Your wired NIC should work with the tg3 module. Is it loaded ?
There seems to be a bug where tg3 is loaded but not broadcom (but tg3 depends on it). Try "rmmod tg3; modprobe broadcom; modprobe tg3" and tell me what "ifconfig -a" says.
See http://dev.gentoo.org/~nelchael/U350-CS20.html for a better fix on this issue.

As for the wifi, can you please give us the lspci output, so that we can identify its model ? The Gateway webpage doesn't state that.

Cheers

You did it! I haven't run ping yet, but here's what ifconfig has to say:

Hello

Once you have eth0, you just have to set an IP, or run dhclient if you have a dhcp server on your system.
Your wlan seems to also be up, did you try it ? I recommend you use wicd to set up your networking [see https://wiki.archlinux.org/index.php/Wicd] but you can use whatever suits you.

Cheers

Eth0's up, and using the settings from the link, it even works at startup, with a pre-DHCP'd IP address. I still cannot ping to my router and beyond, though.

I also realize that I didn't detail my wireless problems entirely. wlan0 is there, and I can even get it to scan access points, but for whatever reason, using the instructions from the wpa_supplicant wiki, I can't get it to assign an IP, or connect to a network. The wireless network where I live is WPA1, don't know if that matters.

I'm sure they're stupid, rookie mistakes that I'm making, but I can't seem to find any concrete evidence of what they are.
