Wireless Networking and Internet Question

[optimus]

I have 3 Network devices in the house, these are:-

A Toshiba Tecra Laptop 1.86Ghz Centrino, with Intel Pro Wireless 54Mbps Wireless NIC. (Running XP Pro).

A 2.8Ghz Desktop, with a New 108Mbps Wireless PC Network Card. (Running XP Pro).

My Work Laptop (Sony Vaio) Brand new, with Intel Pro 3945ABG Wireless NIC (Running Vista Enterprise).

My Question is, I got Sky Broadband Max Yesterday, and was not to happy with the network speed from the first 2 machines mentioned (and even today), only get upto 5Mbps download.

My New Laptop (Sony Vaio), gets a massive 12Mbps.

Can anyone explain why? Is this a PC performance Bottleneck? Drivers? O/S?

I appreciate that I need to get 108Mbps Card for my Laptop, but should the others be that slow?

Cheers

Can anyone help me understand this?

I've tried everything with no joy.

WHat speed are you syncing at on the Sky broadband ?

When you say yo are getting 12Mbps are you talking throughput or are you talking about wireless signal speed indicated ?

What are you using to test the speed ?

Have you tried using a wired connection ?

If I do a a test on Speedtest.net on my other machines, I now get about 8mbps maximum.

On my Sony I Get over 12mbps.

Even If I do one after the other.
