Archer AX10

Had an ORBI for many years, its had numerous minor issues over the years but it finally stopped functioing a month or two ago and I go myself an Archer AX10, quite happy with setup and no issues so far.

tp link AX55, i have ax10 and its very good, the ax55 is the newer version and has great reviews, ive had great experience with tp link

I had this one set up in the same room as my vr headset in access point mode, and it always worked pretty well for me.

Archer Ax10 is also the best option, I am currently using it. I got it for around 13,800.

The 360 slim is wifi 4 (n) on 2.4ghz only, and the router may be putting it on 5ghz. If you can somehow test directly on the 2.4ghz band, that would help. If you can't create a separate wifi network on 2.4ghz, try disabling "Band Steering" if it's an option in the router. That's the setting that tries to put devices on the 5ghz band. The security protocol should be set to WPA2 as well, if it's not already. Anyway, any modern wifi 6 router should be able to handle this. Routers are backwards compatible with previous wifi versions. Here's a TPlink for $50 - https://www.amazon.com/TP-Link-Wireless-AX1500-Wifi-Router/dp/B07ZSDR49S?th=1

i got the walmart tp link ax1500 and have had great luck with it. Like around 50 bucks most of the time.

it has 6ghz

I bought the TP-Link Archer AX1500. 1000 sq ft house.  10 feet to the TV.  Wired to the PC.  Couple phones.   Works very well.
