"Mine has already been making this summer way more bearable than the last. ... It's very worth it for the amount of comfort it affords. I appreciate being able to think about things besides how overheated I am on a warm day. ... Yeah the high summer temps are savage. I cannot operate like that. I'd happily pay hundreds a month to keep my apartment cool when it's 30+ out, at a cost of tens it's not even a question."
"This is exactly what we do too. No point blasting the hvac in the entire house when the only room we want really cold is the bedroom. Has saved us a lot on the energy bill!"

"Actually better than a range extender, as Mesh systems are designed from the ground up to work with each other in the system. ... But it's half ass "patched up" jerky jerky mesh was no match to a Deco. Deco was snappier, more reliable, and longer range."
"I have a primary and secondary mesh access points. The primary is in the house and the secondary is in another small building about 80ft away with no problems."
"I download 50tb a month on my server and steam Plex to nearly ten simultaneous users this way. Never had any issues relating to the wifi side of it."

"I live in a three-bedroom apartment that was built in 1969 and because the walls were so thick, a single router will not cover everywhere. Once I picked up the Google Wi-Fi router and added a single mesh point, my signal issues were resolved."
"Unbeatable set up for the price. Can’t compete with it if you’re living in and old house with thick walls where even standard mesh struggles. ... Been a godsend in our big old house where even mesh networks struggle with the thick walls."

"I returned mine because it was very minimally configurable. ... It wouldn't even let me set it up without internet access, and I wanted to use it in an offline lab. ... That said, it's probably fine for regular users if you have no intention of ever digging into things."
"UI wise? the thing sucks. ... there's just so many basic things you can't do. ... for starters, all the administration has to be done from a mobile app. ... the web based "admin" page just has some basic diagnostics and no ability to configure anything."

"frequently fails to deliver advertised features or function reliably"
"The tplink’s I bought say they support mesh but once setup as a mesh they lose features. ... So the mesh isn’t worth using. ... The mesh setup is a half baked. You can’t use all the wifi features when setup as a mesh."
"I 'upgraded' to a deco system months ago, unaware that this is meant for the average user and advanced features are crippled, e.g. browser config is minimal as they want you to use the app. ... No luck querying the DHCP reservations from a script."

"It’s a good system…..until your modem looses internet and the whole LAN side of your network stops functioning. ... When the internet goes down, Deco gets confused and the general response is that the LAN also goes down until internet is restored."

Yes I used them for years. But then moved to the Deco P9 (mesh power line hybrid) and that's been running great for me ever since. I did briefly purchase the newer Deco PX50 mesh that has power line too but found it absolutely useless compared to the P9. So I returned it and have stuck with the P9.
r/DIYUK • Do these power line extenders really work ? ->No reason to use an Archer if you want to use mesh anyway. Just use the Deco as your router as well for less devices, less cost, more streamlined. Deco or Eero are usually what I recommend for friends that want mesh.
r/HomeNetworking • Advice on getting a router + mesh system ->get mesh system - depending on your current DL speeds that you are paying for you may get away with a pre WIFI 6 system of 2 or 3 units... they go cheap on FB market place where people have upgraded to faster speeds We have TP deco on a 3 story townhouse... 1 on each floor - works well no dead spots like we had before and can plug in apple tv in the lounge to one via a wire... not a massive outlay tbf for good coverage if you are looking for less than 100MB down Look for DECO MESH on FB market place and you may get 3 units of pre WIFI 6 for less than 100 bux... it does enough for less than 100 down
r/nbn • Best location for Wireless Router ->Sounds like you probably want a mesh system. Maybe one with three or more APs (one where the internet comes in the house then two elsewhere) A lot of them work as routers too, but I use mine in AP mode as I have a PFsense router I put together. If your actual router is okay you could get a mesh system and just use it in AP mode. My setup is Modem(virgin hub) > PFsense > switches and stuff > APs Mine are TP-Link Decos. They're pretty reliable and not too expensive but there's loads to choose from. If I had the money I'd like some Ubiquiti ones but honestly I don't have any issues with the Decos. I can't say anything about their router mode though as I've never used it. Tenda is another popular brand but I haven't tried it myself
r/HomeNetworking • Network with 3 access points ->Works fine. Not a single issue
r/tmobileisp • Debating returning to T-Mobile, but I have a TP-Link Deco mesh setup and I'm wondering if anyone has any experience or anecdotes regarding this setup. ->Deco user here, have 4 nodes, all Sonos devices on wifi. Works like a charm out of the box.
r/sonos • Mesh network recommendations ->No issues with band switching, bands are combined and it looks like all speakers are connected via 5ghz. If you are connecting the Deco to a ISP provided modem / router you will need to set the ISP product into bridge mode.
r/sonos • Mesh network recommendations ->Go for Mesh! And get yourself a Deco. Amazing experience
r/IndiaTech • Mesh wifi vs Extendor ->I have a deco, nothing but trouble. Read the tp link subreddit about dropped connections. If you work from home this is not for you
r/BuyItForLife • Best mesh wifi system recommendations ->Deco here as well and never have any Sonos issues, 160square metre house so I have 3 decos to cover it.
r/sonos • Recommendations for good base-only WiFi router to use with Sonos system??? ->Agree, Deco mesh is very good, took a bit of adjusting in my flat - the walls seemed to be lined with lead.
r/DIYUK • Do these power line extenders really work ? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
