How do I renew my DHCP address?

[skrall]

Does Knoppix have an equivilent to Windows "ipconfig /renew"? I have been having problems with wireless nic cards. Configuring a static IP, mask, DNS address and drfault gateway manually is a real pain. I tried downing the interface and then bringing it up again but that did not seem to work.

Hmm, how are you taking the interface down, I'm wondering if you've tried ifconfig ethx down/up or ifup/down. Any additional info regarding the network card, wireless router and version of knoppix might help as well.

Here is the situation. I have Knoppix 4.0 and a DLink G650 wireless adapter. My home network is a cisco 800 router and a DLINK DWL-2200AP access point using a an ESS with WEP. In my neighborhood there is free wifi. When I start KWIFI, I get connected to the free wifi network. I am assigned an IP address in the 172 address space. I can surf just fine. When I use KWIFI manager or iwconfig to change the ESS to my ESS and add the key, I find that I still have the same 172 address. My network is a 10 network. How do I get this wireless card to submit a new DHCP request after is changes to a different ESS?

My wireless card displays as eth0.
I use.... ifconfig eth0 down to shut down the interface.
When I use the "up" command I still have the 172 address.

Thanks,

Try using iwconfig instead of Kwifimanager: http://www.die.net/doc/linux/man/man8/iwconfig.8.html

For some reason, Ive never had much luck with GUI wireless configurators.

pump -i eth0 ...... is the Knoppix equivilent to Microsoft "ipconfig /renew"
