LinuxQuestions.org - Problems configuring Wifi internet connection with Yast.

I suppose the biggest problem is I do not know really what I am doing. After taking nearly a week to install linux my experience amounts to 2-3 hours this morning...so please please keep any answers simple. The stuff below is copied off the screen.....

In Yast...

Under “Global Options” tab:

Network setup method is set to "traditional method with ipup"
Ipv6 is enabled

Under DHCP client options
DHCP client ID......I added a short name
Host name to send says AUTO
Change default Route via DHCP is enabled

Under “Overview” tab:

My card is detected

RT2500 802.11 Cardbus/miniPCI

IP= DHCP

At the bottom of the same page it gives the name of the card again but in brackets it says “not connected”
It also gives a MAC address and a Bus id. It gives a device name and says the IP address assigned by DHCP...

Under “Hostname/DNS” tab:

There is a hostname..... the domain name says “site”

“Change of hostname via DHCP” and“Assign hostname to loopback IP” are both enabled

Modify DNS Configuration says use default policy

The rest of the boxes are empty.

Under “Routing” tab:

IPv4 and Ipv6 gateways ...I typed inthe IP of my router

In “device”... gives a choice of three, I guessed....wlano

The rest of the boxes are empty

In “Wireless Device Settings”

Operation mode = managed
Network Name ESSID....gives name that is correct

Authentication WPA-PSK (is correct)

I entered the pass which was accepted

When I exit it rewrites everything andcloses but firefox still can not find a server...

Any help most appriciated
