Your Actiontec Needs Bridging.

The long and short of this article: It’s about buggy internet connections caused by poor communication between DSL modems and (wireless) routers; specifically, the Actiontec GT701 and Apple’s AirPort.  If you are having internet problems and you have a DSL modem and a router, then you should read this article. I go into a lot of unnecessary explanation; if you’d rather skip the boring details, this link will take you right to the heart of the instructions.  Finally, even if you don’t have an Actiontec or an AirPort, you can probably extract and interpolate what you need from these instructions.
