 |
|
Been trying to figure this out for hours now.
My necesarry drivers/modules are loaded.
Wlan0 is loaded.
Yet when I iwconfig and net-setup or even wpa_supllicant my gentoo still does not want to reach/ping any hosts.
also if i ping my router it says destination host unreachable |

also weird enough...if i boot from live cd i can connect but once i chroot it does not want to connect unless i net-setup again.
and dmesg output that stood out to me(wont let me wgetpaste)
| Code: | | r8169 000:07:000:0 eth0: link down |
let me get on live cd and post my wgets from that.
dmesg from chroot
http://bpaste.net/show/81036/
wgetpaste of resolv.conf
http://bpaste.net/show/81037/
wgetpaste of /etc/conf.d/net
http://bpaste.net/show/81038/
wpa_supllicant
http://bpaste.net/show/81038/

JmpEax,
Are you mounting /proc /sys and /dev like:
mount -t proc none /media/gentoo/proc
mount --rbind /sys /media/gentoo/sys
mount --rbind /dev /media/gentoo/dev
It's been a while, but I think you have to copy resolv.conf to the chroot too.

well i had already done that. btw im trying to get network to work post installation. like its all installed already.
also the re adding resolv.conf did not fix it.
if it helps, net-setup also always clears my iwconfig |

Both are showing /etc/conf.d/net
Try booting to the new installation and redirect or tee dmesg, ifconfig, iwconfig to files that you can later access them from the chroot to paste back.
Also lspci -k and lsusb -v if the wireless adapter is of that type.

JmpEax,
ifconfig shows no ip address and dmesg shows wlan0: deauthenticating
Try something like this in /etc/conf.d/net
| Code: | modules="wpa_supplicant"
wpa_supplicant_wlan0="-Dnl80211 -c/etc/wpa_supplicant/wpa_supplicant.conf"
wpa_timeout_wlan0=60
config_wlan0="192.168.1.105/24 brd 192.168.1.255"
routes_wlan0="default via 192.168.1.1"
dns_servers_wlan0="8.8.8.8"
|
You shoud use you service provider's dns servers.
In /etc/wpa_supplicant/wpa_supplicant.conf
| Code: | ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
update_config=1
network={
ssid="myrouter"
psk="secret"
proto=WPA2
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
id_str="gentoo-laptop"
}
|
Check that CONFIG_MAC80211 and CONFIG_CFG80211 are enabled.
The rest is matching the router to the protocol etc.

Also as a note; the network I am currently on is actually a WEP network with a ascii hex password. I used wpa_config to set it up before so it shouldn't be any different right?
Alright after changing some settings, if i still run ifconfig no ip shows up.
My WPA Supplicant due to my network being WEP
| Code: |
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
update_config=1
network={
# ssid is necessary for psk
ssid="Your-AP-SSID"
# You need double quotes
psk="your-password"
key_mgmt=WPA-PSK
priority=5
} |
Got the internet to work via net-setup. Instead of using WPA-Supplicant I changed my config file. I'll upload via other computer in sec. |

JmpEax,
Try the simplest configuration:
| Code: | ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1
network={
ssid="Your-AP-SSID"
psk="your-password"
key_mgmt=NONE
}
|
You can also try to start it from the cl with debugging messages:
| Code: | | wpa_supplicant -iwlan0 -Dnl80211 -d -c/etc/wpa_supplicant/wpa_supplicant.conf |
-dd will increase the debugging verbosity. That might help with determining the problem.

Thanks for your help. With your guidance I actually figured out how it works and now my internet is running smoothly. Question though. Do I still need eth0 even though I use a wireless interface? |

Glad to hear you got it going 
Since you have an Ethernet controller: Realtek Semiconductor it wouldn't be a bad idea to have it configured just in case.
You can always remove net.eth0 from the default runlevel so it doesn't attempt to start on bootup, but you could start it manually if you should need it.
It's entirely up to you
