DHCP problems.

[polyunix]

Hi guys.

After recompiling 2.6.18 kernel, now each time i reboot i have to type
"# dhclient ath0" to receive IP.
I have no problems when i boot original 2.6.18 kernel. the difference between these two is the only proper type of processor i changed and that's it.
i use madwifi 0.9.3 drv + wep key
# /etc/networks/interfaces
# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
#allow-hotplug eth1
#iface eth1 inet dhcp

# The secondary network interface
allow-hotplug ath0
iface ath0 inet dhcp
wireless-essid my-essid
wireless-key MY-KEY


auto ath0

Any ideas?
Thanks

Make sure the module is being loaded at boot.

lsmod | grep ath

My madwifi module is ath_pci but yours may be ath_somethingelse (you can find out by running lsmod while your card is working). If lsmod doesn't return anything try adding ath_pci (or whatever yours is) to the file /etc/modules

Hi jonantice. Thanks for reply.

This is my lsmod.

# lsmod | grep ath
ath_rate_sample 10720 1
ath_pci 80192 0
wlan 174468 5 wlan_wep,wlan_scan_sta,ath_rate_sample,ath_pci
ath_hal 191088 3 ath_rate_sample,ath_pci

It looks ok.

I think if it was about ath_.... module it wouldn't load the wireless device altogether. Although in my case, it loads wireless, but it cant obtain IP from DHCP, but it can get IP when i choose another kernel at boot.

New discovery.

It loads the network eventually but in 5 min after i login. it's weird. when i boot the other kernel it receives IP on boot process.

Ok.
I found what caused the problem. At one of those updates Debian installed its own madwifi modules and they interact with madwifi modules that i compiled from the source. I opened synaptic and removed Debian's madwifi source, madwifi-tools and madwifi-module.
The problem is solved!
