Ad-Hoc Mode with WEP enryption ?

[Manuel Sahm]

Hello,

my PC has a static ip of 172.168.10.100. (netmask 255.255.255.0). The
LAN Interface has an IP of 192.168.3.211  (netmask 255.255.255.0)
my "linux device" has a static ip of 172.168.10.10. The LAN Interface
has an IP of 192.168.3.141  (netmask 255.255.255.0)


What I?ll do is:

1.) start my linux device (see below)
2.) then go to my pc and look for available networks - the I select my
ad-hoc network called "linksys" and enter the Code ABCDEFABCD. WinXP
says connection esatblished - but no pings are available ?!?!?!?!



Anything wrong ?

Do I have to setup the AdHoc channel on the WinXP host (as a server)
and the start my linux device (as the client) ?

Thanks a lot

Are you sure your computer has an IP address ? You don't have a second
interface (wired interface for example) with the same netmask ? Maybe
the ping is not sent on the wireless interface.

Hello thanks, I tried the following, then I saw an encrypted Ad-Hoc
network on my host PC (win XP) and I try to connect to it. I enter
ABCDEFABCD and the "Connection OK" appears.
But I am not able to seind PINGs ?!
(Without encryption all works fine ?)

Thanks a lot

This is my new procedure - maybe still anything wrong ?

Your hexadecimal key seems invalid, try with 10 hexadecimal
characters.

Hello I tried the following code to get an encrypted Ad-Hoc Connection
to my PC.

Without WEP Enryption all works fine, but if I swtich encryption on, no
encryption is mentioned on my host PC (Windows XP)

This is what I do: - Any idea what could be wrong ?

Thanks very very much
