Reddit mentions of NETGEAR WiFi Mesh Range Extender EX7300 - Coverage up to 2000 sq.ft. and 35 devices with AC2200 Dual Band Wireless Signal Booster & Repeater (up to 2200Mbps speed), plus Mesh Smart Roaming

I bought this a month ago and have been happy with it: https://www.amazon.com/gp/product/B01D6JEMWS/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1

Range extenders work well for fixed devices. Not so much when roaming around the house.. For that, the simplest solution if you don't want to buy an entirely new mesh network router is a universal mesh extender.


NETGEAR AC2200 Mesh WiFi Extender, Universally Compatible Repeater creates your own home mesh WiFi (EX7300) https://www.amazon.com/dp/B01D6JEMWS/ref=cm_sw_r_cp_apa_i_p--QCb4H4SQDM

Or if you have Xfinity, buy Xfi pods for $120 directly from Xfinity to create a mesh set up in the house.

Good luck.

Here are your options for home wifi networking:

1. Buy a super strong wifi router and you're good to go even in a large home - as long as you don't live in a repurposed bomb shelter. An example of a "super strong" router: here
   
2. Buy a normal router or your current one and add access points. An example of a "normal" router: here . An access point (AP) is not a wifi extender. You must run a cable (CAT 5E/ CAT 6) from your router to the location where you need improved wifi signal, there you plug in the AP and attach the Ethernet cable from the router. The AP simply turns a wired connection into a wireless one and broadcasts the same network as that coming from your router. An example of an AP: here .
   
3. Buy a normal router or your current router and use a wifi extender(s). I wifi extender receives packets from your wireless router, ups the signal strength, and then forwards them to a nearby host. If you are having poor signal at point B and the router is at point A then put the extender directly in the middle of the 2; I have seen so many people make the mistake of putting the extender at point B, which defeats the whole purpose because it is just your host device's antenna vs the extender's.
   
4. An extender/AP all in one device. An example: here
   
5. A mesh wifi system. It can be difficult to distinguish a multi-AP/ multi-extender setup from a mesh system, but the main differences are that the mesh will be easier to setup and more "polished" in general. A mesh system will automatically detect the SSID (network name) from the wifi router and extend it. Want to add a signal booster? With mesh you can buy another matching unit and use WPS for a one button setup. The mesh is also smart in identifying when you move from one area to another ans switching to the closer device to server you your packets. Now, this is seen in some higher end APs and extenders such as here , but its not as seamless and usually more expensive in the long run. An example of a mesh system: here
   
   APs are generally more stable (UBIQUITI makes great ones) due to the wired connection. I like using APs because I can buy as I need more and set some up on different VLANs and hide SSIDs, but those are more advanced options. For most people who do not want to run cable or go with more of a permanent networking setup, the easiest and most effective solution is generally a mesh system. The TP-Link one is great as well as Google WiFi.
