securing wifi

Hey guys,
Need some advice regarding security.
My desktop has cis free personal firewall, and works fine. I would like to connect a laptop via wifi but not really sure about security. Does comodo cater for wifi security or is there a recommendation of another product.
Any advice welcome.

The firewall works just the same on wired and wireless connections.

EricJH is correct. Comodo works just fine on a wireless connection. What you might want to also consider is Comodo Trust Connect:

This encrypts your signal so it can’t be intercepted. There is a free and paid version. Please read through to find out the differences.
