Can' connect with Intel wireless 3945ABG and Knopppix 5.3.1

[chip.ling]

alcor,

Sorry I'm a little confuse here. Don't really know how you make it works.

Do you mean you boot up the knoppix from DVD, then you install VMware on the top of it. Then you try to make wireless work. But it failed and you un-install the VMware and try again so it is working?

Can you provide detail steps on what you have done to make it work as well as your setup?

Thanks

Hi Chip,
I try to summarize:

1) Vmware installed on my PC in Windows XP, I had just the program installed, no Virtual Machine running.
2) Restart PC and bootup Knoppix from DVD: DHCP failure (with no ecryption)
3) Restart PC, bootup Windows XP and uninstall Vmware
4) Restart PC, and bootup Knoppix again from DVD: DHCP ok (with no encyption)!

Anyway, even if I'm able to get IP address from DHCP, still I'm not able to connect to Internet (also by ndiswrapper).
I'm not able to ping my router and any host.
Could be a problem of compatibility between Kernel 2.6.24.4 and my Intel card 3945ABG???

Let me kno if you need other details. Thanks

Have no idea why the vmware installed on Windows XP will affect the knoppix. It shouldn't be. But hey, what do I know.

Any user experience the same situation before? Please advise.

If you are able to get the IP address from the DHCP (I assume the DHCP is running inside your router), then you already established a connect between your knoppix machine and the router.

Also I assume all machines are connected to the same router (i.e. they are on the same LAN)

Now can you issue the ping from the knoppix to other machines by using the IP address? Try not to ping the machine by it's hostname.

Assume the other machine you are trying to ping is 10.172.1.101, then issue the command

ping 10.172.1.101

Would wireshark be useful at this point?

Interesting setup, router at 192.168.1.254 and other pc using low IP address 192.168.1.1

Can you perform two more tests please.

1. Try to ping to itself (i.e. ping 192.168.1.100)

2. Try from the other machine ping to this machine.

Rgds,
