"saucony peregrines i like alot ... usually can find good prices ... got a pair on amazon for 50 bucks that was the 13s which r their best year haha"
"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."

"Worked flawlessly from setup and haven’t had to tweak the system at all."
"I have setup three Eero mesh systems for family members. They are super easy to setup and maintain. ... It has been set it and forget it for over three years now. These are installed in houses with users who are 65+."
"My mom actually installed it herself with no problem. ... If you’re not familiar with networking it’s great system."

"2000sq ft split level, but I got it with 3 bases and particularly for the Ethernet back haul as I have one unit in a shed about 75 ft from my house that I ran Ethernet to. (Shed is a converted game space for tabletop gaming)."
"Became FANTASTIC once I strung some ethernet cables among four of them including the one serving as a router in strategic locations (our house is rather large and some walls contain metal lathe). ... We now always have excellent connectivity and fast roaming."
"i noticed a BIG improvement once i conected all my decos via ethernet. ... it was a game changer, i use smart products from different brands and now i don't have any issues with disconections!! ... Some meross plugs disconected all the time before wiring my decos, now they work flawless!"

"They also all support 802.11r/k/v for roaming and fast switching, regardless of wired/mesh uplink. These protocols make devices seamlessly switch APs as they move around, and without dropping connections. You can be on a video call and walk around without interruption."
"The ability to move throughout my house, jumping for AP to AP while having a video call is life changing."
"Recently switched to a UniFi system and no trouble at all with iPhone handoffs on their wifi7 APs. ... Best decision ever."

"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."

craftsman_70 1.0Used Deco M9 would be the ideal solution as they have a dedicated wireless backhaul as well as two normal wifi channels giving you a WIFI 5 with a separate backhaul. Being a few years older, they are also cheap on the used market for what they can do.
enjoylife1788 1.0I have deco m9 plus and it has a dedicated 5 ghz for thr backhaul and therefore its called a tri band router. Even I am looking to add a couple more to the network as I am planning to shift one to another site. But I dont know which new ones have a dedicated back haul radio.
Extra_Tree_2077 1.0Another vote for the deco. I have 2 M9+. Working perfect. Fist bought 3, but 2 was more then enough.
Hairy-Ad-4018 1.0I use these. They are superb.
imoftendisgruntled 1.0Seconding TP-Link Deco. I've got a hybrid set up of M9 and M5 units (including one M5 in a detached garage) that's been rock solid for years.
Lake_Dude_Here 1.0I have been using the Deco M5 and M9 for several years now with my TMHI. Previously used it with AT&T fiber and it has worked the same with both Internet providers. I just used the wizard in their app and set it up in normal mode. I use the ethernet jacks on the back of the TMHI router to feed an M9 in my office that feeds the mesh for the other nodes.
raven8473 1.0Invest in a mesh system , ideally triband ( so dedicated wireless link between units. Previously had a Deco M9 ( can be picked up cheaply ) . Had 3 of them linked in a 3 storey house and was spot on for speeds up to 500 mbps. Easy to use app. Upgraded to a ASUS mesh now due to 1gb fibre .
roman9441 1.0I would said no.2 is wrong if i remember not wrong they adding those web interface for their Deco M5 / M9 later , but later model like X20 / X60 I'm current use have web interface but setting may be not good as in App, but still have most thing you need
Wathii-D 1.0Not true. The M9 Plus - which is a very old Mesh router, has a dedicated 5GHz backhaul channel radio.
YES. The Deco M9-Plus has a dedicated 5GHz backhaul radio. I do wish people would spend 5 seconds checking before guessing an answer! The M9-Plus is a fantastic little router. It even acts as a VPN client, and can create dedicated sub-nets for Smart appliances at a click of a button.
Witty_Ad2600 1.0Hey! The TP-Link Deco M9 Plus and Deco X20 AX1800 are both solid mesh picks. M9 is super reliable, and X20 gives you Wi-Fi 6 and great coverage for 4,000+ sq ft.

Look at TP-Link Deco or Eero. Both are solid mesh options. With 2 floors and a basement, a mesh system with wired backhaul (if you can run Ethernet) will give you the best performance. You can always start wirelessly and run cables later if needed. Just make sure whatever you get supports Wi-Fi 6. It'll handle gaming, streaming, and working better than anything else.
