Ubiquiti UniFi U7 Lite

If you wifi performance issues then the wifi equipment needs an upgrade. Get some good quality access points spread throughout your house. https://store.ui.com/us/en/category/all-wifi/products/u7-lite

Might want to add a U7 Lite access point to ensure the whole house has good coverage.

If you don't need 6Ghz then the U7 Lite is a good option for smaller spaces as well.

Take a look at Ubiquiti consumer grade gear: ATT > Cloud Gateway > PoE-Lite switch(es) > Ethernet to fixed devices & U7 Lite(s) for WiFi 7. 2.4 GHz for IoT, 5/6 GHz with WAP3 for smart devices.

UCG-Fiber, USW-Aggregation, Pro Max 16 Poe switch for main house, Flex 2.5g Poe for other buildings, U7 Pro XG access points as needed for coverage, U7 lite for less used areas, UNVR to record video, and cameras of your choice.

I put in a U7Lite for my house (2200 ft sq), seems to cover everywhere and no issues so far.

I would buy or recommend U7s without hesitation and I think the U7 Lite has a place in small spaces or in homes where many are deployed in a well thought out manner.

Have had a U7 Lite for a small apartment for close to a year now, no drops, or issues so far. Connects well with all 3 types of devices, IoT, phones/laptops, and stationary PC, TV's etc.

the U7L paired with the UDR7 works well for me with about 20 client devices both wired and WiFi.
