Q: I have a 2 story house, can I have 6 hubs? 3 upstairs, 3 downstairs? I have AT&T fiber, router is upstairs in main area, getting buffering downstairs with orginal Google WI-FI hubs.

A: So I’m just gonna say it, “No.” EERO doesn’t work well over about 4 devices and spacing needs to be near perfect or it will mess up handoffs. Speaking from personal experience. We tried using backhaul too and that helped very little. Assuming your house is relatively square, I’d place one on each floor on opposite sides of the house if you have to use EERO. You could probably use 2 Asus or Netgear or TP-Link routers Which would cost around the price of one EERO router. You won’t notice it on TV’s (probably) but you will see what I call “rolling black outs” where the EERO devices disconnect intermittently and reset/reconfigure themselves if you have too many. Even when using Backhaul. Per EERO’s tech support instructions we had about 10 devices scattered across a very large house, cabana, and pool deck and it was a nightmare. Then EERO tech support instructed us to drop down to 3-4 devices and it was still a nightmare…. It at least a different one. Your other question: To get “true” 1Gbps internet speeds you will need a router that can accommodate more than a 1 gigabit connection. This is because there is always network overhead and EERO is brutal in this regard. It applies a lot of tracking info, analytics, and QOS stuff to traffic (most routers do at least some of this but not like EERO. My Asus router allows me to turn all that off for instance). This EERO router has a 2.5GB input from your cable modem but your cable modem must have a 2.5Gb output. In my case, my last ATT router, despite paying for 1Gb speeds, maxed out at 1Gbps so my speeds were around 800Mbps direct from the router. I recently upgraded to an Asus router, Cable Internet, and a Cable Modem (from Best Buy) with a 2.5gb output and now get speeds around 1.2Gbps. If you choose to go with a router and want your full speed, you’ll need to make sure your modem has a 2.5gb output. All that being said, 800Mbps (and significantly less to be honest) is PLENTY to stream to 4-5 HD TV’s while 4-5 people are browsing the internet so your issue may be coverage or jumps through your mesh network.

Q: Do I need a wired router with this?

A: You need to wire one of the Eros to your homes modem the other two do not need to be wired to anything.

Q: Can you hook more than the 3 eero boxes to the system? Is there a maximum #?

A: There are limits, but you will run into practical limits (price and range) well before you run into device limitations. The largest network I've personally seen is 54 eero on a network and that one did work well. The more pressing issue is having eero too close to each other, you want eero to be around 30 to 50 feet away from each other.

Q: Will this router work with a Spectrum modem ?

A: Yes I will I know this because I have spectrum

Q: Tech-stupid here. That being said I start a work from home job that requires an Ethernet connection to their computer (direct connection) can I use one of the ports in the back of one of those "box-things" even if it's not the one connected to the modem?

A: Yes you can. That will provide your computer a hardwired connection to the network (even if the eero it is plugging into is wirelessly connecting to the head/gateway eero, from the computer's perspective it is a hardwired connection). That computer will get as much speed as the eero is getting from the gateway eero. If you need to hardwire more than 2 devices get an unmanaged switch and go eero->switch->multiple devices

Q: What is the maximum distance between units to pick up signal?

A: I'm not sure what the maximum is, but I get a good strong signal in the back of my backyard which I think is about 100 ft from the closest hub.

Q: What is the best Cat 6 cable to use with pro 6?

A: Cat 6 on the cable means it meets the spec so just buy the cheapest. They will all perform the same.

Q: What is the actual speed of each frequency/band? It says it is AX5400 but does not say have fast each band is transmitting. It only says wired at 2.3 and wireless at 1.3 which is only 3.6. Others will say 2.4 @ 600 mbps, 5 ghz @ 1.2 and 2.4mbps.

A: The AX5400 is a marketing term intended to demonstrate the maximum possible speed for all the wireless radios combined. Since these speeds are almost never achieved in real world applications its usefulness is questionable, however the whole wifi market's marketing seems quite attached to it (since it does give an impressive looking number). for 2.4 bands we typically see, in real life situations) speeds from 10 to 200s, 5ghz gives us up to 500 to 600s and we have seen some wireless speeds a bit over 1 Gpbs on the 6ghz band, but 800s is more typical.
