Very outdoor. Outstanding outdoor Wi-Fi — perfect companion for Starlink (even in winter!
Size: 1 Pack Outdoor, Style: Wi-Fi 7 BE5000, Size: 1 Pack Outdoor, Style: Wi-Fi 7 BE5000
I’m using this as the main router at an off-grid cabin, connected directly to a Starlink Mini, and it has been phenomenal. The coverage and stability are far better than the built-in Starlink Wi-Fi router, especially outdoors and around multiple buildings.
This unit serves as the primary node in my network, with a few Deco M5 units extending the mesh, and the handoff between them is seamless. I’m getting reliable coverage over roughly 3 acres, including around the cabin, outbuildings, and yard — something the Starlink router couldn’t come close
It’s mounted outdoors and has gone through freezing winter conditions with snow, ice, and icicles forming around it — zero issues so far. Performance hasn’t dropped, and it’s stayed rock solid.
Setup was straightforward, management through the app is easy, and once it’s running you basically forget about it — which is exactly what i want.
If you’re running Starlink at a rural property, cabin, farm, or large yard, this is an excellent upgrade and easily worth it. Strong signal, wide coverage, and dependable even in harsh conditions.
Highly recommended..!.

Great signal throughout the house and beyond
Size: 3 Pack, Style: Wi-Fi 7 BE5000
Got this set of 3 to replace the single rental EERO that the service provider put in when my mom got fiber. My biggest issue with the EERO was that the service provider set it up, meaning I had no way to control the device. Specifically, my mom is old and apt to click on scam ads or to call the number when a scam popup freezes her keyboard (thanks a lot, Zuckerberg). The only layer of protection I can give her is an adblock DNS, and to do so I need control. Also, I could not get her living room TV to connect to WiFi and signal was starting to drop off a bit in rooms farthest from that single device.
At the time of purchase, this was the most economical 3 mesh device WiFi 7 system from a well established brand. The devices are a bit bulky, but are not eye sores and seem to be very well made. The available wall mount brackets for this style router appear to be more secure than the ones for the cylindrical models, and they won't look as goofy hanging on the wall which is another plus. Mounting brackets are sold separately.
Her TV still does not connect to WiFi, so placed one of these near the TV and connected it via ethernet cable. The third is in one of the rooms farthest from the main base. The range is quite acceptable, with my phone getting full signal strength in the yard @ >50' from the house in some places.
During setup, was given the option to set up MLO WiFi, aka Multi-Link Operation, which creates a second WiFi network that may provide higher throughput than the basic WiFi connection. It is not compatible with all devices, so likely best practice to connect lower need or 'potato quality' devices to the lower throughput base network (phones, TVs, tablets, guests, etc.). The fiber speed is around 300mbps. After extensive Speed Test usage to the point that they stopped allowing me to run Speed Test, both the Base WiFi and MLO WiFi performed similarly with possibly 10-20mbps higher average via MLO. My guess is that MLO may only be truly useful for gigabit connections.
Going straight WiFi with these things doesn't add any significant latency or noticeable drop in throughput in my situation, but could be a concern in larger homes and/or when more walls/junk/metal is between mesh devices. Each of these has 2 ethernet ports, and hardwiring them together with ethernet cable will provide the strongest/fastest connection between mesh devices. The theoretical maximum reliable length is 328' (100 meters) for ethernet cable, so quality Cat6 cable could really put some distance between the main base and the 3rd mesh station (possibly with some WiFi dead spots in between). This is not unique to this system, as most mesh devices have 2 or more ethernet ports.

Great router. Rename devices is easy and a welcomed option. Router reconnects quickly when provider's service drops. Remote access easy to setup. Allows the setup of 2.4 and 5 mHz networks, guest networks, iot networks.
