Is a router configured as a WAP. Routers can be had for as low as 20USD so this is a simple cheap option.
Even cheaper is to move your current WiFi router to it's rightful location which is the center of the house.
Other questions: Ethernet switches are usually 100 megabit and rarely vary in performance.
WiFi range extenders cost the same or more than a WAP or a router as a WAP. I don't consider them good solutions.
Our modem/router is located near one end of our house, and the wifi signal at the other end is patchy and slow. We have Ethernet ports at both ends, so the problem only involves wifi-only devices (iPads and a MacBook Air, which has no Ethernet port).
What's the cheapest and most effective option to get better wifi at the other end of the house if we'd like to use an Ethernet port in that area? Do we need to buy a second router/modem (assuming it's possible to connect two to the same network)? Can wifi extenders take their signal directly from Ethernet? Is there a cheaper/better option?
Also, if all the available ports in the router/modem are currently occupied, are all ethernet switches more or less equal in performance (assuming we'll need to connect another device), or are there some brands to avoid/look for?
Some people say wifi range extenders can be difficult to configure and don't deliver great speeds - is that correct? If so, I'm hoping there's a way of avoiding using one.
Many thanks for your help.
