Random IP Addresses stopping me use the internet

Not sure how best to explain this, as it is an intermittent problem.
I have a macbook pro that uses the internet fine, no problems. I have a small PC laptop that uses the internet fine, no problems. I have a Power PC dual 450Mhz attempting to use the internet, with intermittent problems. I have a 3rd party Realtek wireless card, that I appear to have to keep de-installing and re-installing the OS X Drivers for to get onto the internet. I have broadband through Sky, and an Airport Extreme Base Station. Internet appears to work temporarily through either AEBS or the Sky router (although more problems occur with self assigning the IP address with the Sky router than with the AEBS). When it works I have the following in TCP/IP-

IP Address: 192.168.0.2
Subnet Mask: 255.255.255.0
Router: 192.168.0.1

Occasionally this info remains the same, advises me I am on the internet, but am unable to open any web browsers. If I refresh the DHCP lease, it either comes up with the same info, or a newly assigned IP address of eg. 169.254.162.94 comes up, and I cannot connect to the internet, and each time I refresh the DHCP lease the same IP address comes up.
Does anyone know why this is happening, I seem to be able to go onto the internet for about 5 minutes before something crashes it.
It all works fine on my other computers, I have recently upgraded to 10.4.11 and have 896MB of RAM.

Any help appreciated, Ian

So what is the model of this card, and where did it and its drivers come from? Are these the latest drivers?

The network Diagnostic can be reached directly from:

"So what is the model of this card, and where did it and its drivers come from? Are these the latest drivers?"
- The card came from an online store about 2-3 years ago, it is the RTL8185 and the drivers initially came from the disc that came with the card, and as far as I was aware I had installed the latest ones from searching on the Realtek website, however I could be wrong. I installed the file for 10.4.11.
Any other suggestions or if you can send me the v. latest drivers I'd be most greatful,
regards, Ian
