r/HomeNetworkingCheap Router/mesh system for Apartment

I've used the S4 AC1900 trio (older but worked well), along with the X55 trio. Still Wifi 6 but decent coverage. The one failure was the Eero Mesh 6, stopped working but got a replacement set from Amazon and shipped the old set back. No problems since then.

I ditched the Spectrum router and connected directly to my Mesh router. Works awesome. https://a.co/d/eQkmmO0

r/wifiShould I buy a TP-Link Router?
4 months ago

Best I've owned. No hesitation. I use their DECA mesh with success. TP-Link is a big company. If they do get banned, there will be a pivot towards something the MAGATs will find less offensive. For folks asking what the ban is about. Netgear and other US networking gear manufacturers have been lobbying hard with the GOP, sowing Chinese fears about TP-Link. Not because TP Link gear originated in China (Netgear, Cisco, Juniper, Aruba, and others also have gear made in China), but because TP Link gear is good and much lower in cost, which is eating into their profits. Sales of Netgear have been cratering, so they are asking their GOP buddies in Congress to help shut down TP-Link's US business. Capitalism is good, until you need the game rigged in your favor. Question: Has anyone used TP-Link for small or medium enterprises? How did the installation go (models, qty, client density, etc.), and how is it going?

r/homelabomg just want a new router with good gui and control

Look at firewalla gold pro ... Best router I've ever used in a long time... Understand this is a router only though... This doesn't provide wireless access and way above your budget . Would also need to add access points for that. I don't think you will find anything decent in that price point TBH. ... I had decent luck with TP link deco as well but I find that it could have some better features... Unfortunately if you go with consumer routers you will always find them lacking....

r/smarthomeWhat are some good WiFi 6 routers at the moment?

I have a TP-Link Deco mesh system that was easy to set up and easy to expand. No issues so far for 2 years

r/smarthomeWiFi for Smart Homes: Eero vs Deco vs UniFi
3 months ago

I only have the Deco so that’s all I can speak to. Ive been really happy with it. Easy to set up, works really well, and no issues after over a year so far. It has all the capabilities you would want, including easily setting up separate networks for guest, IoT devices, etc. you can assign your devices to specific access points or use the mesh functionality. Also very easy to expand if you want to add more access points.

r/KeralaAre Wi-Fi Extenders Really Effective?
7 months ago

Wifi extender would reduce the speed considerably. Best option : Mesh network. You'll need two minimum and add on would be 2.5K per mesh router. TP link Deco is what I am use. Second best : buy another wifi router and connect it with the original through ethernet cable. You'll have a different wifi name for the network from the second router so you'll have to switch between connections.

r/HomeNetworkingHelp picking modem and router for small one bedroom apartment
4 months ago

Stick with their Modem, it should be fine for that. Then set their modem/router combo to bridge mode so only the router portion works and sends the internet signal to your new router to do its job Get your own router though. For options, some people like TP Link Decos… I have them right now but lately all of my Apple devices keep having connection stability issues. If you want a prosumer option Ubiquity’s Dream Router 7 or Express 7 are options (UDR7 has a Black Friday deal expiring today)
