First, this probably isnt the right area to post this. Sorry, but im desperate. You guys seem to be good with with computer related equipment. We have a credit card processing unit and everything was working good until we went from Cox cable to DSL. Our credit card terminal now will NOT connect through ethernet..only dial up. We have checked our router that it is plugged into and the port is flickering so we know its connected. All of our computers connect to the internet all day long without issues .Anyone have any ideas!?!? Thanks in advance!
