Replace my Motorola BGW210-700 Gateway with a third party router
I am interested in replacing/upgrading my gateway with a third party router to gain better wifi in my house. I chatted with ATT for 30 minutes yesterday and they said they would email me a guide to do this. Of course, the email never came. Does anyone have a good guide on how to do this. I am only mildly technical. Thanks for any direction you can provide.
