Low ADSL connection speed via wireless link

Archived from groups: microsoft.public.windows.networking.wireless (More info?)

I've just finshed setting up my new ADSL link via a router to both my PCs.

Both are connected wirelessly.

My desktop is fine but my laptop is not getting good speeds from the ADSL.

See my speedtest results here:

Laptop:

Running the speedtest on this site on my desktop displays results that I
would expect, but when run from my laptop is terrible.

My router is a D-Link DSL-604+. It's connected to Virgin ADSL.

Laptop card is a Buffalo 11Mbps airstation card, running on Windows95. It
always connects at 11Mbps at 95% - 100% signal strength.

Anyone have any ideas about what could be causing the drastic slowdown?

I apologise for the lack of technical info, ut I don't really know what to
look for. I can happily look anything up though if it will help to diagnose
things.

Thanks a lot
