[arch-general] Ad hoc

[Ralf Mardorf]

The PPPoE connection works after running '# ifconfig eth0 up && netcfg pppoe' as usual.

After preparing ad hoc [1] I loaded the module by '# modprobe rtl8192se'.

Then I tried to run 'newlan -n', but it doesn't work [2].

1. How can I run 'newlan'?
2. Do I need to reboot to load the firmware?
3. Do I have to change the lines

modprobe -r ath_pci
modprobe ath_pci autocreate=adhoc

to something like

modprobe -r ath_pci
modprobe ath_usb autocreate=adhoc

when using an USB device?

[root at archlinux src]# modprobe -r ath_pci
FATAL: Module ath_pci not found.
[root at archlinux src]# modprobe ath_usb autocreate=adhoc
FATAL: Module ath_usb not found.
[root at archlinux src]# modprobe ath_pci
FATAL: Module ath_pci not found.

Rebooting now without a starting the adhoc script or loading the module at startup ...

Regards,
Ralf
