Deco X5700

3 xe75 pros, 2 on 1 level, 1 upstairs for about 5 months, greenlight 1 gb and ran flawlessly. Added 2 x5700 which are similar but discontinued. One x5700 is ethernet wired to basement tv. Home theater, main tv, streamer all ethernet, no issues. Recently the software was not responding or wouldn't respond to prompts . Rebooted the main, and all problems disappeared and the basement tv which i discovered has ethernet connection capped at 100mbs, responded faster. The 5700 won't update for some reason but not an issue. Only baffling thing is the 5700 closest to the shed doesn't push a signal to the rear of the house. Adding a tp link camera soon so it should connect to that node.

I have both deco's and cuddy's the decos you can get from costco though (3 pack) and they were pretty well but the bad thing is they kind of stop updating after a year or two. They also go on sale very often at costco. I am unsure on cuddy's as I just got them for testing. I also do bypass though so I don't even use the bgw620 even though I have one.

First off, sorry to hear about the lightning strike — that’s rough, glad at least two units survived. Mixing in Wi-Fi 6E/7 with your existing Wi-Fi 6 Decos won’t really unlock their full potential, since the mesh will still lean on the lowest standard. Unless you plan to replace the whole setup, you won’t see a big jump. If your two current units are still covering fine, the safest move is just adding another Wi-Fi 6 Deco to keep everything consistent. Wi-Fi 7 is great long-term (throughput, latency, efficiency), but right now it’s only worth it if you’re going all-in or already have a bunch of 6E/7 client devices. As for the AX-50 Outdoor — it’s solid for extending coverage outside (yard, patio, garage). It’s basically just a weatherproof Deco, so don’t expect crazy speed boosts compared to indoor nodes, but range is quite decent.

To be fair, if you don't have any WI-FI 7 devices, it's not really necessary (IMHO...), plus, as someone else mentioned, having that dedicated back-haul comes in clutch for mesh networks, going from the original google home hubs to a linksys WH02 system (example, not a recommendation) greatly increased our speeds on anything connected to a node (as long as it was only one hop, there's one way in the back that's two hops, but it's still pretty fast). We actually have the (a) WI-FI 6 deco system now with Gig internet, and we get excellent speeds throughout the house and yard (again, as long as it's only one hop). To answer your question, sorta, tri-band helps enormously, to use an analogy... dual band mesh is like you (your cell phone on wifi say...) trying to make a phone call to your mom (the mesh node), who's on the phone with your brother (the main node/AP), everything you say has to go through your mom to get to your bother, and then back to you, because she can only listen or talk at one time, also she's in a loud shopping mall. With tri band, your mom just holds the phone up to the other phone so you can talk to your brother directly, there's still some overhead and noise (she walked into a hallway or something now), but the information gets through a lot faster. eta: idk a simple walkie talkie VS phone call analogy may have worked better...

TP link deco mesh triband works great.

Plus one here for Deco. I have four WiFi 6 models. Mesh is a better solution I agree. WiFi 7 models are still very expensive but few devices are compatible at the moment so for me WiFi 6 is the best option for the money.

Your problem is simple. The router Spectrum gave you is weak, and it is sitting too far from your room. You do not need Ethernet in every room, and you do not need to touch the coax ports at all. Ignore the video you saw. You also do not want a “wifi extender.” Those cut your speed in half because they repeat the signal instead of creating a real network. Here is the easy path: 1. Buy a two pack mesh system. One unit replaces the Spectrum router and plugs into the Spectrum modem with the same cable the old router used. The second unit goes in the hallway or living room halfway between the modem and your bedroom. You only need power for the second unit. No coax. No Ethernet. 2. Set them up using the app that comes with the system. It takes five minutes. The mesh units talk to each other wirelessly and create one strong network. Your bedroom will get full signal because the second unit is right down the hall instead of across the whole house. 3. For brands, eero 6 or TP-Link Deco 6 are fine. They cost about 100 to 150 dollars for a two or three pack. Put it on your Christmas list. Either one will be miles better than what Spectrum gave you. 4. Do not overthink MoCA or powerline. They work in some houses and fail in others. Mesh is the least headache and works in almost every small house. If you do those steps your PS5 will stay online and you can stop fighting with the signal.
