I've got a bit of commercial and home experience in networking, and I've just upgraded from an Orbi 4 node WiFi mesh (WiFi 5). I've tested the results across the board and I'm very, very impressed.
My internet bandwidth was previously throttled by my 1Gbps backbone, now increased 20% from 950Mbps to 1150Mbps. The 2.5Gbps ethernet upgrade works perfectly for the backbone and for wired 2.5Gbps clients. A new 2.5Gbps switch was also installed to support the LAN. There is zero latency across the entire ethernet network, even when traffic is routed through multiple BE65 nodes.
All WiFi (5 & 6) client devices have had a huge upgrade in available coverage and bandwidth, with speeds increased by 50-100+%. So much so that I returned a USB WiFi 7 modem I got for my WiFi 5 gaming laptop, the high end WiFi 5 adapter in the laptop got an unbelievable 100%+ increase in bandwidth with the BE65's! Internet speed test results show 1150Mbps, 13ms ping. Over a 1.4Gbps WiFi 5 connection!?!
The entire set up process was smooth and easy (I had done some planning), we have 20% increase in broadband bandwidth, blazing 2.5Gbps ethernet backbone and LAN, 100% WiFi coverage that is an astonishing minimum 500Mbps (tested), everywhere, even in previous dead spots where there was very poor WiFi coverage previously. Roaming is completely transparent. The WiFi performance of the BE65 is at pro/commercial levels, this alone would sell me, even at this price.
As a tech I'd like a little more access in the interface for administration, but when something works this well, I'm not sure I'm going to need it as much as I used to. I'm a pretty critical person but I'm struggling to fault this system for my purposes, especially on performance and value for money. Compared with the old Orbital system it's on another planet. It's future proofed with WiFi 7 and I can't imagine why I'd ever need anything more in the foreseeable future or ever TBH.
Well done Tp-link on a great product. It's rare for me to be so impressed with new tech.
