On: Ask HN: How do you secure yourself on public WiFi?

For those who don't want to setup their own vpn, you can try hotspotshield. It's free but they display a ad frame as you browse.

I setup vpn on my dd-wrt router.

I'm sure this is not the perfect answer since hotspotshield redirect somehow google search pages and force ads on every page. But you can get the ads away with a simple rule in .hosts file. Privoxy can add another layer of ad protection.
