Repeating Xfinity Hotspot
My mom's house is right down the street from my grandmother's house. My grandmother's house has a decent signal to the local Xfinity Wifi Hotspot, but my mother's house is too far out of range. What I want to know is, with something like DD-WRT, is it possible to set up a router at my grandmother's house that can repeat the Xfinity wifi so that I can have connection at my moms house? The Xfinity hotspot is very barely visible at my moms house, even when using a Buffalo WZR-HP-G300NH and DD-WRT, I can see it on the SiteSurvey Client List, and can even join it, but for some reason, the way I have my router configured (which I'm not all too familiar with and its very possible I just don't have it properly configured) doesn't allow me to then connect to my router with my laptop and have the client wifi traffic repeated back to the Xfinity hotspot.
Can someone suggest getting the router to work? Do I just need another wifi router plugged into the Buffalo once the Buffalo is in guest/client mode?
