No wireless in OS X (10.4.11), but works in XP mode!?

[Skygoing]

Just as the title says, I can't get the ip addresses, etc., in OS X, nor can I get into the router's internal settings with OS X but I can do both with XP running on the same iMac.

Everything had been working fine, then a few days ago the internet would stop working and we'd get it back up after a modem reset, but now that's not working either. I have a new modem on the way but afraid that it's a software issue/bug. Not sure why I'd get perfect wireless in XP but not in OS X if it was the modem.

I've deleted the four files from Library/Preferences/SystemConfigurator to get rid of the "settings are being run by another program" issue, now just can't get online at all. When I check and renew DHCP, I get addresses like
"169.254.195.191."

Any thoughts? Ideas? (shotgun is not an option for now)

Follow the photos should be easy enough, btw im using 10.5.5

Hope this helps any problems ask.

Edit: Added smaller focus, and words

no dice...

I appreciate the response but even when I type in a manual ip address-- or all my information manually-- it still isn't working. for some reason I think the computer is recognizing the SSID but nothing else, as my SSID is showing up in the wireless signals list but I can't even log into the router using a web browser, unless I'm in XP. URG!
