My router is WPS-incapable, being that it runs Tomato; most Linksys-based WRT routers do not implement WPS in any way, shape, or form, so that vulnerability is right out the window for those of us running alternative firmware on Linksys gear.
I was confused by your post at first because I have a WRT160N v2 which is vulnerable and isn't (last time I checked) compatible with DD-WRT or Tomato. Then I realized that you were referring to DD-WRT.
To clarify, any Linksys/Cisco router that is capable of running DD-WRT or Tomato is not vulnerable to Reaver because these firmware versions do not support WPS. It's the open-source firmware (DD-WRT/Tomato), not the stock firmware that comes with the router, that is safe.
http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&articleid=25154It's been a while since I checked the above link - hasn't changed much since the beginning of the year. Clearly Linksys/Cisco is saying "SOL" to most of the owners on that list with older hardware. I'll likely never buy a Cisco/Linksys router again because of this.
