I have 3 computers all hooked to the same router by wire and all 3 are havign laggy and unresponsive internet regardless of which web browser I use. I called my ISP and theyre saying that they're running at the speeds they're supposed to be but clearly this is not the case. After they tried to fix the issue they decided to send a new router. Is it possible the router is the cause of the issue and if not what else could cause this? Any information is appreciated, thanks.
