madwifi and Kubuntu 7.04_64
 
I had my D'Link 510G card working with my Westell 327 gateway for a short time. Th. only mod I made was to change 'dhcp' to 'PPPoE' in /etc/network/interfaces because my ISP doesn't use dhcp. Then I had to shut it down to test memory form my other system. On reboot, after a couple of commands to get scanning back up, I can no longer connect. Trying to reach a URL through Firefox or trying to ping from the command line woih result in 'network unreachable.' I have no security key set as yet. I have tried all the twconfig commands I can find in the madwifi first-time how-to but nothing helps. What am I overlooking?

Possibly you have a mixture of DHCP and pppoe. To see what you acually have try the following commands:

lspci -v

ifconfig

lsmod

Check the man pages for each command to interpret the results.

Clarification
 
I'm going to go out and make some assumptions based on what you've said, tell me if they're correct.

1. Before you made the changes, your connection worked fine, and you could reach URL's.

2. You're connecting through a wireless access point, model Westell 327, which also serves as your router

Now, I'm guessing that you changed to PPoE on your client machine? If so, this is probably not what you want to do. Your client will still use DHCP on your local network, getting it's address from a lightweight DHCP server running on your router.

Just for fun, switch back to DHCP on your client, and see if it works. Your main goal is to see if you get a valid IP address, then to access your gateway's website address (192.168.1.1 possibly) Your gateway is where you'd have to specify PPoE, I believe. I'm not too familiar with this technology, but I do know that from what you've described, you're probably still going to want to use DHCP on your local network.

1. Yes, I could reach URLs after I changed /etc/network/interfaces to PPPoE (but not before). When all I did wal reboot after a brief shutdown, I can no longer reach URLs or ping the W327 (or any other address including that computer's own).

2. Yes, I am attempting to connect wirelessly thru the W327.

The gateway's network address is 192.168.1.254. Question: Is that what is being sought at all stages of setup, or is there another number I should use? It seems to me that sometimes the ISP is referred to as the gateway, but maybe I'm wrong.

I changed PPPoE back to dhcp in /etc/network/interfaces but that didn't help. There are some dhcp settings remaining on the W127's setup screens, but PPPoE is still specified on the one designated DSL Connection, which is bellsouth's standard.

What mystifies me is that between working and not working, I changed nothing, leading me to believe that something was dropped or changed during reboot, but I don't know enough about the internal functions of madwifi (or Kubuntu) to know where to look.

Problem solved. I tried two different addresses I had seen for gateway, entering them from System Settings | Network Settings } Route. After reboot, I connected. Thanks for your help.
