View Full Version : Diagnosing dropouts

I do have a Linksys WAP54G - two to be exact.  One is for laptops, tivo et. al.  The second is for sb's and runs on a seperate channel.  However, note that currently, only on sb runs wireless and it is fine.  The problem child is currently hard wired through the powerline and does not at any point go wireless to get to slim.
