Router A is directly connected to the internet.  It is the internet gateway
that AT&T put in when we got our internet.  Router B is connected to the
internet through router A via Ethernet.  If I connect to Router A, I can't
connect to anything connected to Router B.  However, I have a wifi printer
connected to router A.  I can print to it from a machine connected to
Router B.  Router A is AT&T UVerse and Router B is Netgear.  I attached a
USB wifi card to my laptop and have it connected to both networks at the
same time, but I don't want to do this permanently because I have another
laptop where the internal wifi doesn't work and I only have this one USB
wifi adapter.  I could buy another one from Amazon, but I'm sure there's a
way to do this with routing or port forwarding.
