Hey take my questions worth two grains of salt but have you considered the tp-link deco mesh they are pretty inexpensive compared to orbi imo. And they are interchangeable (e.g. one x20 as the main and 3 s4’s)

I’ve been using TP-Link deco S4 and a wifi 6 one for some years now

Five year old router technology. I suggest upgrading to a mesh network. Try the TP-Link Deco S4 system for testing purposes.

I had my PS5 working on wifi and was having these stuttering issues, however when I ran it direct to my deco, it cleared. Also using Xbox cloud gaming and it runs amazing. From casual games like octopath traveller to demanding games like fortnite. ISP verizon FiOS 300/300 tp link deco S4 mesh wifi

Consumer-grade equipment often can't handle dozens of wireless clients efficiently. Assuming that your setup is like this: Bridged ISP > Primary S4 > Switch > The rest of your stuff . . . then you should be seeing decent wired speeds. If you get 1GB speeds when directly connected to your ISP's route

Ok, I understand what you are doing better now - there is no need for the MI's to sit behind the TP-Link so by connecting them to the switch you are taking the TP-Link out of the path for them to reach the internet (Nokia) Is it correct that the Nokia is acting as the only router in your network and

Get a mesh network router. Put one in your window, put the other in his. I.e. the TP-Link Deco ( is the S4 or better ) or MERCUSYS Halo H60X ones or better.

Get a wifi extender or maybe two - they can create a mesh network with your downstairs wifi router and extend your wifi as far as you want. 2.4 GHz Wifi can only go maybe 100 feet where there are walls or floors, or 40 feet for 5 GHz, so you may need multiple wifi extenders to daisy-chain their way
