Great Upgrade — Worth Every Penny
Configuration: 3-pack, Style: without eero Plus
We previously used the dual‑band eero 2 model, and it served us fairly well. After doing some research (and getting a little help from Copilot), we upgraded to the eero Pro 6E — and the difference has been incredible. We bought the 3‑pack, but quickly realized that 2 units easily covered our entire home (~2,000 sq ft). It’s not a loss, though; we’ll leave 2 behind for the family when we move and bring the extra 1 with us and we can buy another single unit later if needed.
For context, we pay for 800 Mbps, but with our old modem/router combo we were only getting 70–150 Mbps in most rooms. Zoom calls were hit‑or‑miss, and the layout of our house doesn’t help — the modem is stuck in the far right corner of the house, and moving the line would require some construction/rewiring = $$$. After installing the eero Pro 6E, we’re now consistently getting 350–680 Mbps in every room, and even our garage pulls around 300 Mbps. That’s roughly an 80% improvement without touching any wiring.
Setup was straightforward. Since we have a modem/router combo, the only tricky part was remembering to turn off the router portion. Once the main eero was connected, our devices automatically joined the new network since we kept the same Wi‑Fi name and password. From there, placing the second unit halfway through the house filled in the weak spots that we use to have.
The speed and stability have been game‑changing for our hybrid/WFH household. We run Ring cameras, smart plugs, a MyQ garage opener, Google devices, and smart lights. For the smart lights, garage and smart locks, I had to manually reset the wifi though and 2 out of 7 of the ring cameras.
Pros
- Very easy to set up, especially if you’ve used eero before
- The app makes managing devices, checking status, and updating Wi‑Fi info simple
- Excellent coverage for homes with dead zones or awkward layouts
- Truly plug‑and‑play — anyone can get this running
Cons
- It’s definitely pricey (we were lucky to have a gift card that covered most of it)
- Much larger than the older eero 2 units — about 2.5× the size
- Works best elevated on a table, so don’t leave it on the floor
Overall, if you’re struggling with weak speeds, dead spots, or a modem stuck in a bad corner of the house, the eero Pro 6E is absolutely worth considering. It made a dramatic difference for us.

Wanted to like this, but had to return... and return was not easy.
Configuration: 3-pack, Style: without eero Plus
This review is on the EEPRO 6E tri-band mesh. I'm not a network novice so after my bad experience I wanted to warn people away from this product. In my 25 years working in technology infrastructure I've acquired experience, network certifications, etc believe me when I claim I'm not stupid. I live in a three floor house on an acre lot so have little external signal penetration into my home. All rooms I wired with Cat6 for gigabit ethernet. My internet service is 1Gb; from the wire I speed test at 800 Mbps down and the same upload. No one in my family wants to plug in anymore so we all rely on three independent wireless routers connected by wire and bridged into the network: a netgear nighthawk (2,4Ghz and 5Ghz bands) on floor two, a Verizon gigabit router (2,4Ghz and 5Ghz bands) on floor three and an apple extreme (2.4Ghz band ) on floor one in the basement. From my apple phone (12 pro) I consistently get 550Mbps download and 300-400 upload except on the basement router where my office is. I wanted a mesh to improve signal handoff and for my office to get the same as the rest of the house. I picked this one because I read good things and the price was discounted compared to the orbi which at $2,000 I just could not bring myself to buy.
The installation of the first node was easy (connect to the wire and run the app) on the second floor, the second node complained it was out of reach on floor 1 (directly under node one & connected to the ethernet wire). After two attempts to find it, it worked. The third one was a nightmare. Tried putting it on the other side of the house and connect to ethernet and just would not pickup. I had to bring it one room away from node one before it picked up. Job done? Well the first day I had 450 Mbps download and 400 upload everywhere. Thinking I was happy.
Next day, "Dad we have no wifi!". My wife tells me she was dropping connections from her laptop all day within 20 feet of node 2. I thought ok I'll reset the system. Re-input all their devices with fresh connections. That worked for 24 hours. Next day, I'm sitting in the room with node2 and it affect me; 1Mbps download .01 Mbps upload. I renew my connection, no fix. Reset the system and back to 450 Mbps. I check any firmware updates, nope all current. I thought maybe the node below #2 was too close, so moved it an additional 15 feet away to lessen any signal cancellation. Next day,"Honey why did you buy this, it slower and worse than our old system?'. Yep it's time to return. So the old network went back in and all iphones and macbooks are happy again.
Here is the worst part, the return. I initiate the return, pack it all nice and find out I can't drop it off at the UPS store. Why? Because Amazon will only process the return if they pickup from my home. Ugg, but fine. Here is where it goes downhill...you have to wait for a phone call from the carrier to arrange a pickup. After a week of waiting for a call and answering numerous telemarketer garbage calls, I decided to call back customer service and find another way because I have to travel for work and can't wait at my house for a phone call. The only other way - is to pay for shipping yourself. So um why can a return label or QR code be processed for anything else but not this product. Very Dodgey. Do yourself a favor and pick another system or maybe the mesh is just not worth it. PS. I did find out that the system ( even though it has a 2.5Mbps network port) is rated as one of the slower systems when it works. I could never get it as fast as my existing netgear with is over 2 years old.

FULL POINTS!!!
Configuration: 2-pack, Style: without eero Plus
After repeated, torturous attempts with other routers to replace the wifi network provided by our beloved Apple Time Capsule, we are relieved and thrilled to have landed on the 2-unit eero Pro 6E router. Hallellujah!
Among other things, the eero routers (and their mesh) were trivial to set up, the support was great (and barely needed), and a great surprise, the eero routers automatically connect to our wifi-aware HP LaserJet M401dw printer (via a feature in the eero routers called Universal Plug and Play, or uPnP), so that I don't have to choose the printer's wifi before printing. And oh yeah, the eero routers' mesh covers our 1,600-sq ft house nicely, with great signal speed and strength, and automatically chooses my Mac's fastest wifi speed.
TIP (old news to most of you, I presume): To provide additional ethernet ports from the routers, I bought and installed the inexpensive, high quality "NETGEAR 5-Port Gigabit Ethernet Unmanaged Switch (GS105NA)", which required no setup at all, except that the switch must be connected to either of the eero routers after the eero router is connected to your cable modem, so that your ethernet service can recognize the additional ports provided by the switch.
My only complaint is that setting up the eero routers requires a cell phone, and as I love macOS for its legacy self-evident user interface, I hate cell phones! But that said, set up with the cell phone was trivial. So...
FULL POINTS!!!
PS. Despite searching hard, I never found a router that supported Time Machine backups via wifi, which was possible with the Apple Time Capsule. Instead, I have adopted Apple's present guidance to make Time Machine backups to an SSD (removable flash drive). I use two, keeping one in the house and one in the car and swapping them with every backup. Works fine, but I miss Steve Jobs!

Very easy set up, plays nice with smart devices.
Configuration: 3-pack, Style: without eero Plus, Configuration: 3-pack, Style: without eero Plus
I've been using the system for a number of months now. I had an aging Netgear Orbi system that was working well enough but due to the way the system works, it was difficult to get it to work with the smart devices in my house. I have a number of smart locks, security cams and outlets that had issues hooking up. I decided to change to the eero system. I have a main unit and three satellites. The main router is on the top floor of my two story house and I have one in the basement. I have quick speeds throughout the house no problem. I'm pretty good with tec stuff but was worried that I'd have to go through setting up each device again on my system when I switched over. I got each of the eero devices up and running with the latest firmware. Set them up with the same SSID and PW's of my previous system. I unplugged my old system and restarted the eero's and everything just, worked. All my devices connected. I was expecting to have to manually add one of my security cameras or maybe a smart outlet. I'm using a few smart systems like Netvue, VeSync, U home and Gosund. They all work without issues. I was little shocked frankly. I was expecting some sort of issue I'd have to start googling but no. I wish there was a web base app but it's not a big issue everything is through a phone app. I pay My ISP for a 1GB Download and am seeing just about that wired and wireless 650+ MBps so it's plenty fast. I have a MoCa device to my Nvidia Shield streaming device and that's also seeing 950+MBps. It's been very stable, I haven't noticed any drops or speed reductions. Not that it matters too much to me but each of the stations are pretty small and look pretty good compared to my old ones. All in all a worthwhile upgrade for me.

Great Product
Size: 1 Camera
Great camera for outdoor security. The features on the app have been updated and work better than the Ring Doorbell.
The camera has a great live picture, and the sound is very clear.
