Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Eero is also good and is on sale Amazon Prime day. I used Eero 6+ . I use Ethernet cables on computer, printer and TV. and also have Ethernet to each Eero access point. Ethernet not required but is best.
Mesh. The kits often come with 3 nodes. One or more for each floor I use Eero but others will also work. That may fix it but if not see if there is a chase between floors for pipes so you can run Ethernet, one cable to each node on each floor
Yep same I have 3 x Eero 6+ in a long old double brick semi and it works a treat. No need to hardwire anything. I used to have TP-Link but the Eeros are much easier to setup and more reliable.
I'm using the eeroesh system. I have the eero 6+. There's newer versions now, and noticed multiple subnets. You can just buy one and setup a new one as an extender with no issue, or buy one with a network jack and use it as a wired extender. I don't have the eero 6 pro,but I still get nearly 959 or greater for download and 850+ for upload speeds on a 1gb line. On wifie purely it's in the 700 to 800 range. I am a computer person, I understand networking, I'm a solutions architect and know how to troubleshoot so many random things. The EERO system has been insanely easy to setup and has been crazy reliable. Have had eero since 2022 and haven't had a single failure
A simple eero 6+ system would be fine with like 2 nodes. You could easily run an Ethernet on your ceiling if you have hurricane proofed walls like I do to power your other WiFi
So what I did was get an Eero 6+ mesh and run it out the back of my Att modem. Since the speeds upstairs were not the best I ran a 150ft Ethernet cable along the ceiling into the office into a switch for my wife’s office setup (she was getting 100mbs speeds prior) then hooked the other eero mesh to the switch and now the upstairs gets 800mbs on WiFi. I thought about doing it to the living room but I was getting 7-800mbs on my streaming PC so I assume all devices hooked to that eero via the switch are good.
Did eero max 7 get released recently? The reason I am ask is because I have eero 6+ and my connection has been AWFUL as of lately
