Nighthawk X6 AC3200 Tri Band WiFi Gigabit Router (R8000)

I'm looking to upgrade my router. My current router is: Netgear Nighthawk R8000. My current internet speed is 250mbps download and max (limited due to coax cable and that my area isn't receiving fiber for another 3 years) 100mbps upload. My house is 2 stories, roughly 1600 sqft. Wifi to upstairs bedrooms sit above the same room my router is located. Only ethernet cable I'll be using is for my ps5. Any given day I have about 7-9 devices connected which has worked decently well with my current router but I'm rebooting more frequently and sometimes 1 TV upstairs has some lagging issues. I'm accustomed to routers that have 3 bands. Currently 2.4ghz is connected for 1 phone and 1 tablet. And the two 5ghz bands are connected to 3 TVs, 2 phones, 1 laptop. Ethernet for ps5. I've read about Wi-Fi 6/e. I believe 6e will work best and for my current devices. I can't decide between brands. I thought TP-Link had some controversy a few years ago but I can't find it now. Linksys, I hate that you must use their app to sign in. Netgear, my only complaint about them is firmware updates. If anyone can guide me to a router that fits my usage, I'd be forever grateful. Thank you.

I'll have to look into vlan as I have a vague idea for what it is. But that's one thing I enjoy doing as long as products support it is installing/tinkering custom firmware, custom Os', etc... My router hasn't had a firmware update in like 4 years even though end of life stops in a year or 2.

Im at 499 plan and my poco M5 had frequent disconnection in the nokia router, but i upgraded X6 pro have no issue, still airtel kind of poor in range

Of course! We have Netgear Nighthawk (X3)

I dont know about this model but fuck Netgeat Nighthawk. I owned a different one few years ago that was supposed to be a a high spec version, and it caused me infinite problems, which all disappeared when I bought a different one.
