I have a wifi broadband router, an iMac and PC

Router = 192.168.1.1
iMac wifi = 192.168.1.4
iMac ethernet = 192.168.2.4
PC wifi = 192.168.1.2
PC ethernet = 192.168.2.2

I have a crossover cable connecting the 2 machines. The idea being they should be able to swap files over the ethernet cable fast and still access the internet via the router.

It works fine on the mac side. The problem is on the Windows machine if I browse //192.168.2.4/mark/ at first it will be at ethernet speed, but after a couple seconds it will slow to wifi speeds. How can it be using the wifi interface when I am browsing the IP 192.168.2.x? given wifi is on 192.168.1.x?
 
Have you turned off wifi altogether to ensure its not a different issue?

What exactly is wifi speed in your situation?
 
Yeah I tried this.. it doesn't work... the WiFi needs to be turned off.

That is the only solution.
 
Configure both computers so that :-

They are both using static IP addresses.

You don't need to put in a default gateway.

You only need the IP address and the subnet mask, the DNS server should be 172.0.0.1

Disable the wifi and re-attempt a transfer. If it still slows than the issue is not that its using the wifi for that transfer.

This worked, in case anyone was wondering +++

172.16-31.*.* is an internal range, like 192.168.*.*; You could have alternatively used 10.*.*.* as your addresses. I'm pretty sure your problem came down to subnetting, that is, blocking out what range of addresses you're communicating with.

From your original post, if traffic is truly going over wifi I would suspect your subnet mask is 255.255.0.0 rather than 255.255.255.0. Was this the case?
