I have my Fios wireless router in the garage. My home office is on the topmost floor in the corner furthest away from the garage. My gaming PC and work laptop are connected to a switch that is connected via the wall Ethernet outlet. This is perfectly fine for those two machines, but I get garbage reception for my phone and tablet in this room.
Should I change the switch to a wireless router? I assume a WiFi repeater wouldn’t work, unless it’s place on a lower floor with decent reception, since these don’t have an input Ethernet port and receive the signal wirelessly themselves?
Keep the switch and add a dedicated Access Point in your office to give you a new strong source of WiFi in that area. The Access Point I recommend for such scenarios s the Ubiquiti U6 Lite or Pro.
You can also use any off-the-shelf, all-in-one router like an ASUS or Netgear to do the same thing. Just put this router into “Access Point Mode” according to its manual. You can either just attach it to your current switch, or use the router’s 4 built in LAN ports as a switch and then use your existing switch elsewhere.
I think the U6 Lite is pretty much replaced by the U6+ now
