I know very little about setting up networks, so I would like to ask you all for advice. In my house I currently have a router that emits wifi signals at 2.4 GHz and 5Ghz. My router is placed at ground level and I have a couple of ethernet cables running through my house, all the way up to the attic. What I would prefer to do is to have some sort of access point in my attic, that is connected to the router through one of ethernetcables, that will function as ‘amplifier’ for my wifi.
What I saw online is that a repeater performs this job, but is usually presented as a device that picks up the wireless signal and amplifies that instead of signals coming from a wired connection. Can I set a repeater up in the way I described?
Yes, most devices marketed as repeaters that have at least one Ethernet port can be used to provide a wireless connection from a wired connection, usually called AP Mode. TP link Explination of modes of multimode devices
I would recommend a dedicated Access Point (AP) device rather than a multi-purpose device though.
