Keychain Assistant

Hi all,
I'm actually a PC guy, but I could use some help for a friend of mine. I set up a wireless network for a friend of mine with a Macbook Pro, its about 2 months old, probably with Leopard as the OS.

I can not get her laptop to get on the internet using wifi. I made a few adjustments to the setup and have a couple ideas. I have a linksys wrt54g in an upstairs closet and a dynex DX-WGRTR set up as an access point in the downstairs.

I have no problems getting online using a PC and I have no problems logging on to either router through the AP with her Macbook. Her Macbook also has no problems logging on to any other network. When I attempt to go to any address besides 192,168.1.1 (upstairs router) or 192.168.1.2 (access point) safari comes up with a ...you are not connected to the internet.

The wifi used to have WEP encryption on it, then I changed it to WPA, and currently it is wide open due to the difficulties I have had. Ok, so is it possible that keychain is getting confused since we have had so many different configurations under the same network name that it will not let us go any farther than the gateway? At one point after I opened the network all the way up, it asked me for a WEP key that shouldn't have been needed.

EDIT: I think I may have tried to use a hex WEP key and not ASCII or the other way around and confused it also.

So how would I go about deleting all entries from keychain that reference this network and anything else I should do to basically make it into a 'new' wifi network as far as the laptop is concerned.

Thanks for any help you can give an old PC guy.

 

is this correct?

Open keychain access located in /applications/utilities
choose edit>keychain list
delete anything relating to the wireless network 'Tracey', the linksys router, or the Dynex router



also, is there a way to delete all network locations from the network configuration screen?
