Trouble getting 2nd VLAN to connect to internet

Experts,

I have the following config (see below) running on my Cisco 1811 router.  When I connect a pc to Fe1-Fe8  with a 10.10.10.0 network address then I am able to fully connect to the internet.  However, when I connect a pc to Fe9 with a 10.10.20.0 address I am not able to connect to the internet.

When I have PC's plugged into Fe2, Fe3, Fe4 and Fe9 and then issue a "show ip int brief" command on the router it returns this:

Interface                       IP-Address       OK?   Method   Status                            Protocol
FastEthernet0              223.103.5.175   YES   NVRAM  up                                  up
FastEthernet1              unassigned       YES   NVRAM  administratively down   down
FastEthernet2              unassigned       YES   unset      up                                  up
FastEthernet3              unassigned       YES   unset      up                                  up
FastEthernet4              unassigned       YES   unset      up                                  up
FastEthernet5              unassigned       YES   unset      up                                  down
FastEthernet6              unassigned       YES   unset      up                                  down
FastEthernet7              unassigned       YES   unset      up                                  down
FastEthernet8              unassigned       YES   unset      up                                  down
FastEthernet9              unassigned       YES   unset      up                                  up
Dot11Radio0                unassigned       YES   NVRAM  administratively down   down
Dot11Radio1                unassigned       YES   NVRAM  administratively down   down
Vlan1                           10.10.10.1         YES   NVRAM  up                                  up
Async1                        unassigned       YES   NVRAM  down                            down
NVI0                            223.103.5.175    YES   unset      up                                 up
Vlan2                          10.10.20.1          YES   NVRAM  up                                  down

The 3 computerss connected to Fe2-Fe4 are able to get online and ping their gateway (10.10.10.1), but the pc on Fe9 cannot get internet access and cannot ping it's gateway (10.10.20.1) although windows shows it to be connected.

What do I need to change in my configuration to allow VLAN 2 (10.10.20.0) to get up and working?
