I find speed test shaky at best. Wildly varying results, I don't know of any alternatives though sorry.

I got this earlier today.

Personally speaking I wouldn't worry about your results Stu.

I would only be concerned if there was an actual problem.

netsh interface tcp set global autotuning=disabled

Also disable IPv6 in your TCP/IP settings as depending on your vista version or service pack level it try's IPv6 before 4

switch the whoring vista tcp auto tuning off and give it a try matey

Hmmm, didn't do too well there .....

global command failed on IPv4 The requested operation requires elevation.

Sorted

right click the command prompt shortcut mate and run as administrator

Not much change -

Here's a test for you.

Ping using the other machine. Then connect yours to it via crossover cat5, turn off wi-fi and try again.

Your ping should match the other machine. If not then clearly a driver issue. If it does, yet when running alone it doesnt ping well, then check your router settings.

Some routers can throttle everything but the master registered machine/MAC.
