OS: Windows 8

I have a cabled NIC (connected to router with ip 192.168.1.0) and a WIFI NIC (connected to a router with ip 192.168.1.1) . I want all traffic to go through the cabled NIC, except the 192.168.1.0/8 range should use the wifi-nic.

This was working fine in Windows 7, without any manual configuration. In Windows 8 however, it's not.

My routing table:

I added the rule for 192.168.1.0. I would think Windows should use this rule for the IP 192.168.1.1 because it's more specific than the default-route.

However it's not:

C:\Windows\system32>tracert 192.168.1.1

Tracing route to 192.168.1.1 over a maximum of 30 hops

  1    58 ms     4 ms     4 ms  192.168.0.1
  2    68 ms    12 ms    11 ms  ^C

So... What do I do wrong? And how can I make Windows use the wireless NIC for 192.168.1.0/8
