I have a tp link deco mesh network, initially it was 3 nodes. I’m up to think 6 nodes now across probably 10k square feet over 2 levels. For the most part, it’s been perfect.

I like my Tp link deco 400 unit. It can handle Wi-Fi 6 and Wi-Fi 6E

I used to have a TP-Link AC1200 router. I’m not sure if it was because I was torrenting for a longer period or more torrents, but the router would throttle to 1 Mbps. I’m not sure why this happened, but when I rebooted the router, it would work fine again. This happened a lot, but it happened less often with the ASUS router.

I live in a 4600 square feet house. The modem aka the main router is downstairs and the download speed is 300 Mbps and upload speed is 100 Mbps. The router which is near my room upstairs gives me a speed of 30 Mbps the name of the router is tp link ac1200. What router do you recommend budget $300.

I have a 3000 sq ft home and tricked tplink 3 deco unitsand am disappointed with it. Numerous units drop connection and it doesn’t cover my entire house. My 5 yr old orbi system never had these issues

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?
