Pros: Works OK as a normal single WAN router. I use it just fine with only my cable modem attached.

Cons: When I plug my DSL modem into the router so that I have a dual WAN connection (cable and DSL), the modem fails to operate for normal internet usage. For example, if I go to a site that uses a secure connection, with HTTPS:// in the URL, the websites fail with the dual-WAN connection. An example of sites that break down: internet banking, PayPal, and Google Adsense. If I want to access these sites, I must unplug one of the internet connections from the back of the modem. I can find no settings that will allow the modem to work with secure websites.
