hi
I couldn't get the wireless to work after the installation. There's no wired connection and the pc that I've installed gentoo can connect to the network when booted with systemrescuecd.

The files that I modified according to the hand book are

Code:

 /etc/conf.d/net file:

#This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d.  To create a more complete configuration,
# please review /usr/share/doc/openrc*/net.example* and save your configuration
# in /etc/conf.d/net (this file :]!).


modules="wpa_supplicant"

wpa_supplicant_eth0="-Dmadwifi"


and
Code:


 /etc/wpa_supplicant/wpa_supplicant.conf file:

ctrl_interface=/var/run/wpa_supplicant

ctrl_interface_group=0
ap_scan=1

network={
  ssid="mySSID"
  psk="myPassword"
  priority=5
}

network={
  ssid="mySSID"
  scan_ssid=1
  psk="myPassword"
  priority=2
}



the lspci:

The handbook should really, really stop mentioning any other driver than nl80211 or wext. Madwifi is completely outdated. Modern drivers use nl80211, then there's a few that use wext.

Anyway, your lspci doesn't contain any wireless devices, so it must be an usb adapter. Check with lsusb.

certem,

When you locate your wireless device change your /etc/conf.d/net wpa_supplicant line to include the configuration file.

Code:
modules="wpa_supplicant"
wpa_supplicant_wlan0="-Dnl80211 -c/etc/wpa_supplicant/wpa_supplicant.conf"

I added the lines you mentioned accordingly but there's an additional line in my file which says
Code:
iwconfig wlan0="managed"


I put it because the info I got when booted from systemrescuecd told my connection was "managed"

I'll give it another try by removing that line. If still can't connect I'll post the output of lsusb in 8 - 10 hors when I have access to the computer that I installed gentoo.



Edit: Additional info.

/etc/wpa_supplicant/_wpa_supplicant.conf is the default path for wpa_supplicant.conf

so all he really needs is:

Code:

modules="wpa_supplicant"
wpa_supplicant_wlan0="-Dnl80211"


not hugely important, just a random tidbit for future reference.

Thanks, thats an interesting tidbit. Every guide I remember seeing always had the path to wpa_supplicant.conf so I always included it.

I tried both but still no connection. (I also tried with and without
Code:
iwconfig wlan0="managed"

)

Code:
wlan0     IEEE 802.11bgn  ESSID:"mySSID" 
          Mode:Managed  Frequency:2.437 GHz  Access Point: 00:12:BF:FD:D6:9E   
          Bit Rate=18 Mb/s   Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:on
          Link Quality=41/70  Signal level=-69 dBm 
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:8   Missed beacon:0

lo        no wireless extensions.

I'm confused (and probably shouldn't butt in) but the iwconfig
lines above show you are connected just fine ...

That doesn't tell me anything unless you provide how you've configured the kernel.

Anyway, you need the rt2800usb driver and the linux-firmware package.

recompile and recopy the kernel. Reboot. If a kernel configuration or lack of firmware problem was corrected the network will connect if no other problems exist.If no connection, run
Code:
 ifconfig
output should show wlan0, confirming that the kernel can find the rt3070 device and that it is up. If wlan0 does appear, run
Code:
 iwlist scan wlan0
which should find your access point. If wlan0 is not shown by ifconfig, mount the boot partition, run
Code:
 ls -l  /boot
the kernel date time should be very recent, check grub.conf is using it.

I did the changes but still no connection.

I tried to read the boot screen by ctrl+s and ctrl+q there were errors like

1) waiting for uevents to be processed... timeot... some usb problems

2) eth0 and/or net.eth0 not found...

I'm going to try yo post that screen.

after rebooting to gentoo did you run
Code:
 ifconfig
If you did, did ifconfig output show wlan0?
Apparently your ethernet device driver is not configured properly in the kernel kernel config or there is no ethernet device. This should not affect wifi.

the urls are:

and

I booted the computer with systemrescuecd and ssh'ed to it from another computer to mount and chroot in. I hope this doesn't have any effects on the outputs.

your kernel config for wireless is good, wlan0 should appear in the ifconfig output.
boot gentoo
Code:
ifconfig > /ifc
ls -l /boot > /lsl
uname -a > /una
iwlist wlan0 scan > /iwl
nano /etc/rc.conf

edit rc.conf to include
Quote:
rc_parallel="NO"
and
Quote:
rc_logger="YES"
without # in front of them.
reboot to cd and enter the chroot, then run
Code:
wgepaste /ifc
wgetpaste /lsl
wgetpaste /una
wgetpaste /var/log/dmesg
wgetpaste /iwl
and post the url's

when convenient rebuilding kernel with

just checked and find sysrescd has wgetpaste.
you are thus able to boot sysresccd, mount gentoo partitions and run
Code:
wgepaste /mnt/gentoo/ifc
wgetpaste /mnt/gentoo/lsl
wgetpaste /mnt/gentoo/una
wgetpaste /mnt/gentoo/var/log/dmesg
wgetpaste /mnt/gentoo/iwl
to avoid entering the chroot.

suggests that uname -a > /una was run with the sysresccd booted as opposed to beiong run with the installed gentoo booted.

if iwlist scan ran from gentoo, the interface is proven to be up and runnimg. if ifconfig ran from gentoo, dhcp is obtaining an ipaddress. this leaves only wpa_supplicant as a likely problem.

boot gentoo, Try

psk="yourpwrd"

network={

as your /etc/wpa_supplicant/wpa_supplicant.conf.

try
Quote:
modules_wlan0="wpa_supplicant"

wpa_timeout_wlan0=15
iwconfig_wlan0_mode="Managed"
config_wlan0="dhcp"
dhcpcd_wlan0="-t 10"
as your /etc/conf.d/net. After the changes are made, run
Code:
/etc/init.d/net.wlan0 stop
rm /var/run/wpa_supplicant/wpa_cli-wlan0.pid
rm /var/run/wpa_supplicant/wpa_supplicant-wlan0.pid
/etc/init.d/net.wlan0 start
ping -c2 192.168.1.1
if the ping works, reboot gentoo, ping again to ensure the connection starts automatically at boot.

Well done. A victory for the orderly approach. in /etc/conf.d/net you can change

wpa_supplicant_wlan0="-Dwext"
#wpa_supplicant_wlan0="-Dnl80211"
to
Quote:
#wpa_supplicant_wlan0="-Dwext"
wpa_supplicant_wlan0="-Dnl80211"
nl80211 gives a speed improvement over wext (when it works)
