My main router (it is a router/modem combo) sits on one of the far sides of my 1st floor. My garage is at the other end of the first floor, and then there is the 2nd floor which in about half of the areas receives poor connection. I know there are many ways to do this, but I am looking for a way to extend the wifi range without loosing speed. Currently I have a Cat5 running from one of the lan ports on my main router/modem, out through a window, back into an upstairs window, and into lan port 1 of my 2nd router (router only). Not the WAN port. I have it hooked up as all one network that way when I'm walking around the house my iphone automatically picks up the stronger signal. Now I BELIEVE that I was told this doesn't cut bandwidth. Not sure though. Does it? The method has been fine for me, except as you can imagine it's not the best looking. I recently heard about powerline or homeplug av devices. Something like that. I'm not sure if they are the same, but I'm sure you know what I mean. Would they do what I want? I'd plug my 2nd router into the adapter so I don't have to run an obnoxious cat5 outside. Would that work without cutting bandwidth?
Also are there any other or better methods you could tell me about? Thanks! I'm not unwilling to buy new equipment so if a different method involves that don't hesitate to tell me, please!
Sorry for going on guy!
