Linksys - Velop AX4200 Wifi 6 System - 3 pack - White

Actually, you can use one pack, two packs or three packs. It all depends on the size of the home and how much area you need Wifi. I would begin with a two pack. Any of the units can be used as the router, which would be the one you connect to your gateway. The other unit(s) will serve as extensions to that pack. You can buy a two pack system now and if needed, you can extend it by obtaining an additional pack. Decide now which Wifi network you wish to install. Linksys has their network wifi mesh systems in either Wifi 5 or the newer Wifi 6 standard. Hope this helps.

First, it will depend where you have placed your device. I have one placed on an outside wall as close to my outbuilding as I can get ( I have the 3 device mesh system). My outbuilding is about 65 ft from the closest device. For about 50 ft or so between the buildings I get a good signal. At the outbuilding I had limited signal - sometimes it would connect and sometimes it would not or drop. I already had range extenders from my previous wifi system and when I added a range extender on the house's second floor and one in the outbuilding, I got a good signal in the outbuilding. So I would expect you should have a good signal if you are only 10 ft between the two structures. But once again it depends upon where your wifi device is located in relation to the outbuilding.

Yes you can, buy another pod and pick the right place for it, remember it's an indoor product.

Each node has Ethernet plugs. You can hook up a hub to them as well. We’ve loved these since we bought them.

Yes, all 3 nodes are identical but have their own SSID/Password/Recovery Code sticker on the bottom just in case you and 2 friends want to split these nodes up to run them separately in your respective homes. By connecting one node to your internet modem and using it to set up a new network within the Linksys App, you are designating it to be the primary node. Any other nodes you add to it will become secondary nodes. Please note that you cannot daisy-chain secondary nodes. Each secondary node must have a good connection to the primary node.
