How many units is too many?

Currently running 3 wired eeros. Getting decent reception bars for all 50 or so devices. Ordered a 4th eero to be wired also. Hoping to tweak for maxing signal everywhere. 

At what point do eeros start interfering with one another ?  Had 4 Google Wifi units but found signal degraded so went back to 3. Wonder if Eero is better equipped for this?

    Thanks for the question! There really isn’t a limit to the number of eeros. A good rule of thumb is one eero for every 1,000 square feet with eeros being no more than 50 feet apart.

    With that said, the more space you are looking to cover, the higher the odds are that there will be some sort of interference (walls, electronics, doors, etc.). It really just depends on the space, but following that general rule of thumb, you shouldn’t see any interference between eeros.

    Also, if you are wiring some eeros, this will help avoid any interference between eeros since they’ll use Ethernet as the network backhaul.

    Hope this helps!

      Jeff C. So, If I have 6 EEROS in a 3200 sq ft, 2-story home, 3 up stairs and 3 downstairs releativelly equally spaced from each other on each floor and in separate rooms, I should see no interference between EEROs.  Correct?   I have a wood frame, stucco house in Arizona.  I want to maximiz speed but also want to maximiz option to use ethernet ports on EEROs without using any external switch and to have all units on an EERO Pro 6E mesh network.  I have about 75-100 devices, most HUE and LifX lights connected anyone time.

      myeero There are a few folks on EERO's Reddit group who would say no more than 3 or 4 EEROs in my case,

      myeero That is likely way to many eeros. You effectively only have 1,600 sq/ft on each floor, so I'd reduce your eero setup possibly all the way down to just 1 eero per floor (try it out and see), or maybe 2 on one floor and one on the other depending on where you are able to actually place them. I have a 2,600 sq/ft single story residence with the same construction materials and I can get by with 1 eero Pro. I do run two but just because I need some devices hardwired into the 2nd one.

      Depending on the room layout of your home, you might get by with 4 max, but 6 is too many and will be causing interference with each other.

       I'm in ~4500 sqft home and reducing my Eero count from 7 to 5 seemed to significantly reduce my wifi issue - at least for the last few hours so far since I made the change.

    Thanks much for your answer. Will let you know when I get the 4th eero in a few days. I have outside Nest cams that are situated right next to aluminium soffits and window shutters. Lots of interference like that everywhere in the house.

    Am getting mostly 5 bars at the moment with a couple 4 bars, and a couple that occasionally turn to yellow for a few seconds then back to 5 bars. Not sure what’s up with that but everything works so far. As long as the eeros don’t interfere with each other (or rather, devices have issues  switching between eeros), things will be good. 

    So far, eero has been excellent and stable. Hopefully things will be even better with eero #4. 

    Wondering if software updates always reboot the eeros, thus disconnecting everything, or are they done in the fly.  

    Best

      cotedan87 I’m not sure exactly what the schedule is, but automatic firmware updates have always seemed to be applied in the middle of the night. As far as I know each firmware update will reboot the eero.

      You can always apply an update manually through the app without having to wait for the automatic schedule to apply it.

      cMoo92 Many thanks. I would prefer if updates didn't reboot the routers to ensure 24h nonstop coverage.  Google Wifi updates itself without rebooting. Perhaps in future updates, Eero will be able to do so. So far, 3 days, Eero wiredx3 is perfect. 4th unit coming. Should have bought the company instead :)

      cotedan87 in a perfect world reboots wouldn’t be necessary, but one reboot every couple of months in the middle of the night isn’t a big deal.

      I’m also very very surprised to hear that Google WiFi doesn’t reboot when it updates. I’m pretty sure every network product I’ve managed (everything from consumer to enterprise grade) reboots after a firmware update.

    In my experience with other routers *(e.g. Google Wifi), 50 feet is a long way in a house, and most houses aren't 50 feet long. I rather say decent range is 25 feet and if you have refrigerators or stoves in the middle of that, likely down to 20 feet and not with full speed.  Just my experience anyway. 

    My soffits and window shutters are aluminium. Furnace and kitchen stainless appliances. Wrought iron furniture and wine rack. 50 devices competing for bandwith.  

    Thus, getting 4th Eero to cover entire house - two upstairs, two down, all wired. Should be good.

      cMoo92  thanks again for the reply.  How I know about reboots is through my Nest cam history.  They can buffer a bit but if it’s for 2-3 minutes I’d get an email that my cams are offline. Never happened with Google Wifi. 

      Liking the eeros so far, and nice to see a person like you who’s used them enough to be helpful to others. Many thanks. Let’s continue the dialogue.

      cotedan87 That's interesting to hear. I have two Nest cams on my eero network and I don't recall getting offline notifications due to an eero update. I just timed my gateway eero rebooting and it was 90 seconds. I know my Nest cameras connect to the gateway eero, so maybe your cameras end up being offline for longer because they are connected to a leaf eero which would be offline for a little longer.

      cMoo92 could be indeed. I’ll have to watch. I do know the cams have some buffer because under other modem reboots, my cam history would appear intact.

    How many would you put in a 2,500 sqft house?

      googlehome_or_eero Three would probably cover it, but I wouldn’t do more than 4. I have 3 in my 2,200 sq/ft house.

      There’s a lot of variables when it comes to the layout and construction materials of the house so it’s not easy to give an accurate estimate.

      googlehome_or_eero - Our last house was 3600+ sqft.  2200 sqft main level with one Eero (wired) and 1450 sqft basement with 2 Eeros (wired).  We had 5 bar service everywhere in the house and 4-5 bar service within 25 feet of the house.  I could see signal strength taper off over 150 feet past that.  I've been so impressed with the system as a whole!  Ran for 2 years there with no hiccups.

    I have a huge home - 9000 sq-ft - with very think walls.  I know I will not get perfect WiFi, but looking for decent, certainly in the areas that I use the most. 

    i think I need 6 eero for all the comments I have read.  Unfortunately, all will have to be wireless.
    Any suggestions?  Thank you I’m advance.

    I had 3 Eeros in my 3384 sq ft, 2 story house, but recently added a 4th one now that the POE one has been released to install as a Ceiling WAP.  I haven't played around with placement of the other 3 Eeros.  One is the Gateway and would stay where it's at.  But the other 2 can be moved around to different locations in the house to spread coverage better.  

    I have noticed lagging at times when on my cell or laptop connected to the Wifi...so maybe i need to play around with it more.

    I have 4700 sq. ft. on two floors plus detached garage 50 ft. from home.  Home was built in 1905 with all plaster/lath walls.  WiFi has been generally poor throughout the home presumably due to the wall construction.  I subscribe to 300mbps fiber synchronous Internet service.

    After replacing my Apple Airport Extreme with a Linksys EA9500 things got better.  Then I replaced that router with 8 (yeah, eight) eeroPros currently in use.  WiFi still isn’t phenomenal by any means but a lot better, and I do have 20mpbs or so in the garage.  The gateway eeroPro is Ethernet to the modem but everything else is all WiFi with essentially no way to hardwire.  Typical WiFi speeds in the home are in mid-double digits, say 40-70mpbs of the 300mpbs available.

    I’ve taken some of the eeroPros out, moved them around (a lot), actually considered getting more of them, but nothing has really changed my WiFi coverage for the better.  I’ve also considered replacing these devices with the newer eeroPro6e though 6 or more of these really gets expensive.

    We’ve learned to live with this.

    I have six eero's - three stories, rather wide house, basement, and interference between rooms/floors keep the signals from propagating cross-house.  It's enough to where I can put two on each floor at complete opposite ends and get decent coverage.  I walked around and did a site survey for signal strength, and we did plenty of moving the units around to determine optimal placement.  Signal is good on both systems and in the app.  Of course, 2.4Ghz is crap around here with everyone else and all the other iOT things, but the other bands are clear enough, including the new 6GHz band.  

    It's all dependent on your house, what it's made of, the configuration of the rooms, and a site survey.  Get a network friend to help you do one and make a site plan.  Set up temporary placement of the units and experiment before mounting them.  Lots of people start at the center, but in our case, we couldn't get the edges that way, and had to do opposite ends.  Watch your power levels, look at the app for interference, and your connected systems will also give you an idea of noise, TX rate, etc.

    It would be helpful if Eero troubleshooting would let you know when congestion is high and suggest trying using fewer eeros.
