All of the above.
Since Jumbo Frames increase the Message Transfer Unit (MTU --- the payload size per Ethernet frame), each network device needs to support Jumbo Frames to work over that link.
So, look for an MTU setting in your router, look at the drivers for your network adapter in Windows, and change the interface config for your Ubuntu box.
In Windows Device Manager, if you view the Properties dialog for your network adapter, the Advanced tab should have a setting to enable Jumbo Frames or set the MTU to ~9000 bytes, if your adapter and driver supports them.
In Ubuntu, you should be able to enable them then restart the network interface.
To enable it for the eth0 network interface:
# sudo ifconfig eth0 mtu 9000
To make the change stick on reboot, edit the interfaces file:
# sudo vi /etc/network/interfaces
Add the line:
Write and quit in vi, then restart the interface:
# sudo /etc/init.d/networking restart
Check the route to your router for "mtu 9000":
# ip route get 192.168.1.1
192.168.1.1 dev eth0 src 192.168.1.100
cache mtu 9000 advmss 1460 hoplimit 64
