Both bands have great coverage - make sure to orient one of the antennas parallel to the ground, that can give you a good performance boost.

Easy to set up, gives good coverage and great speed.

I was hoping for better coverage at the far end of my house

Easy to set up, good coverage and no dead spots.

It’s coverage is great and speed is consistent downstream and up no matter where I am in the house

Good coverage

The coverage is as good or better in some cases

It gives good coverage on the main floor

much better coverage

A great router with strong signal and great coverage, much better than the Netgear R6300v2 and the Tp-Link 1043NDv3 even with 8dbi antennas, both at 2.4 and 5G.UI a bit sluggish though but not as important after set up.

Good wifi coverage.

Installed it on the second floor of our 3,800 sqft house and the coverage is pretty good throughout the house and backyard

Great powerful router with great coverage.

Very fast, easy setup, great coverage

Provides great coverage even being placed in the basement.

This AC66U B1 now supports AiMesh, so just pick up several of these and sprinkle them around the house with it, it'll definitely have better coverage than a single AC5300, which are gimmicky at best...

I thought this would be a great way to solve teenager home network load issues with 2 nodes and 'Mesh' to improve coverage in the house

Added this to my 68U ac1900 to add additional coverage to my house and it works awesome! so happy with it.

Quality isn't as good as

The only thing that does not work as I would like is the url and keyword filter, but this is a known problem with filtering some webpages, as the router instructions say it cannot filter any secure website that use compression or https; although it will filter pages that have only http

The range is good, as I can use the WiFi portion in any room of my house as well as in my detached garage

The 5g is fast

Great 2.4 and 5G performance.
