TP-Link - Archer BE9500

Both could be problematic. A single WiFi device may not be enough to cover both floors in a home. If a single device were enough, the BE9500 would be better because it's tri-band WiFi 7; the AX3000 is dual-band WiFi 6. The AX3000 gives you two mesh nodes but you're trying to get them to receive WiFi between floors. It appears that they can do wired backbone so if you can run an Ethernet cable between floors, the AX3000 is going to be a better solution than the BE9500. Full WiFi 6 coverage will beat partial WiFi 7 coverage.

I have the BE9500 from previously netgear orbi 971 after it started boot looping, but I’m happier with the TP-Link.

I dumped Google's Nest Pro for the TPlink BE95 and been great! Real wired backhaul, and wireless if you want. I think that you probably want a wired backend. Do you have coax cable in your home? You can link everything up with Docsis 2.5 GBps using those runs without having to run new wire. Alternately, you could look Ethernet over power. I think they have 2.5 Gbps for that too.

absolutely not using tp-link, it started out good and it just too much headache BE95 was just horrible

Tp-links newest WiFi 7 router is sick for the price.

Stay far away from routers with fans, I returned a tp-link wifi 7 router over this exact issue. Sfp port was so hot it was unreal. Try to cool your place in summer with air conditioning, you don't want some fan blowing heat. Also moving parts is a bad idea for longevity. Also when I ran latency tests I was loosing O.4 to 0.8ms over fiber with the tp-link, my old router from 10 years ago never added that much latency, just to give you an idea of how bad fans are. This is not enterprise, cisco is enterprise and they use heatsinks not fans. If you want a decent router for home, Netgear rs700 uses heatsinks and has 1500 more sq ft of range than this thing, yep not 2000sq feet, but 3500sq feet, should get good reception in your backyard this summer. If you want enterprise you'll have to go cisco.

They are incredible and simple. I’ve had a setup with the WiFi 6e ones, and now have one with WiFi 7 ones. Literally stellar performance. Do you have first hand experience?
