LFS wifi

josh102595 · 01-07-2014, 09:58 AM

so I have been trying for days now to get my lfs build online, I have tried wicd, wireless tools, and wpa supplicant (maybe a few others but I can't remember)

Anyways I am completely lost. I know nothing about networking. I found some info about my wifi on my current Ubuntu system, I don't know what is useful about it but:

Code:

General
Interface:           802.11 WiFi (wlan0)
Hardware Address:    00:25:9C:A7:98:A0
Driver:              rt61pci
Speed:               54 Mb/s
Security:            None

IPv4
IP Address:          192.168.1.113
Broadcast Address:   192.168.1.255
Subnet Mask:         255.255.255.0
Default Route:       192.168.1.1
Primary DNS:         72.240.13.7
Secondary DNS:       72.240.13.5
Ternary DNS:         156.154.70.43

IPv6

The name is linksys and it has no password. Can anyone help me please...

Did you compile the module for it when you compiled the kernel? "Driver: rt61pci" That's the one you need.
If you run

Code:

ip addr

does it show wlan?
You can also check with

Code:

ls /sys/class/net

to see what your kernel found. If wlan is not shown you don't have the correct module for it.

ipaddr:

Code:

root@josh-Vostro-220-Series:/ $ ip addr

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

ls:

Code:

ls: cannot access /sys/class/net: No such file or directory

So your wlan is up and you have an ip adress. Can you ping google?

Code:

ping -c 3 8.8.8.8
ping -c 3 www.google.com

josh102595 · 01-07-2014, 12:34 PM

does it matter that i am using chroot environment not an actual boot?

Code:

root@josh-Vostro-220-Series:/ $ ping -c 3 8.8.8.8

Lennie · 01-07-2014, 01:00 PM

Then the problem is in /etc/hosts. (This is still valid, but a later problem...)

Indeed it does... For example you're using Ubuntu's kernel and modules. You don't know yet if you have that module in LFS... And you're already connected to wifi from Ubuntu's Networkmanager, and already have an IP, so the router thinks you're Ubuntu...

Try everything again when you've booted to LFS.

josh102595 · 01-07-2014, 01:37 PM

okay, on boot i got these messages:

Code:

interface wifi0 doesn't exist.
interface eth0 doesn't exist.

Then I re-ran all of the codes you guys posted:

Code:

root@Vostro-220-Series:/ $ ip addr
1: lo: .....lots of junk.....
2: sit0: .....lots of junk....

Code:

root@Vostro-220-Series:/ $ ls /sys/class/net
lo sit0

Code:

root@Vostro-220-Series:/ $ ping 8.8.8.8
Network is unreachable

Code:

root@Vostro-220-Series:/ $ ping www.google.com
unknown host

You need to recompile the kernel and find and add the needed module, as shown above: 'rt61pci'.

ReaperX7 · 01-07-2014, 03:47 PM

Can you post the readout from lspci first before proceeding?

Rebuilding the kernel is one thing, but often there are some wireless cards that require firmware to be installed to use, or a proprietary driver.

josh102595 · 01-07-2014, 04:04 PM

kernel rebuild with the above option enabled...

all of the commands had the same result but I go this on boot:

Code:

eth0 does not exist.
Bringing up wifi0 interface...
Unable to process /etc/sysconfig/ifconfig.wifi0
Either the SERVICE 'wpa was no
*****sent or cannot be executed

I don't know what that means but my /etc/sysconfig/ifconfig.wifi0 file reads:

Code:

ONBOOT="yes"
IFACE="wlan0"
SERVICE="wpa"

# Additional arguments to wpa_supplicant
WPA_ARGS=""

WPA_SERVICE="dhclient"
DHCP_START=""
DHCP_STOP=""

# Set PRINTIP="yes" to have the script print
# the DHCP assigned IP address
PRINTIP="no"

# Set PRINTALL="yes" to print the DHCP assigned values for
# IP, SM, DG, and 1st NS. This requires PRINTIP="yes".
PRINTALL="no"

run lspci from Ubuntu or LFS?

josh102595 · 01-07-2014, 07:57 PM

if I run lspci in my lfs system I get:

Code:

root@josh-Vostro-220-Series:/ $ lspci
bash: lspci: command not found

from Ubuntu:

ReaperX7 · 01-07-2014, 09:18 PM

Ralink drivers should be in the kernel. I don't think they require firmware either.

Check your kernel configuration and see if it has the appropriate driver modules selected for your hardware.

Just a suggestion, but I use the Slackware(64)-Current Testing 3.12 Huge-Kernel config for my kernel config and it works and has a lot of hardware supported.

lspci is part of the BLFS pciutils package.

http://www.linuxfromscratch.org/blfs.../pciutils.html

josh102595 · 01-07-2014, 09:48 PM

you mean for this?

Code:

04:01.0 Network controller: Ralink corp. RT2561/RT61 802.11g PCI

That is already configured into my kernel

EDIT
now when I do lspci on LFS I get the same output as I do from Ubuntu

ReaperX7 · 01-07-2014, 10:01 PM

Okay, since you have this... next question... are you using a Static IP or DHCP for connectivity?
