Question Will I get full 1200 Mbps Wi-Fi connection?

Hi!
I have MSI Z690 A PRO motherboard with 2.5 Gbps LAN port, which is connected via CAT-5e cable to ASUS AX58U router, which supports wifi-6 and has 4 1-Gigabit ports.
I use that to wirelessly play VR games on my Quest 2 headset which supports up to 1200 Mbps wi-fi speed.
The router is in the same room and roughly 2-3 meters from my playing zone.
My question is, assuming all hardware is working properly, since 1200 Mbps is technically more that 1 Gigabit, does this setup give me full 1200 Mbps bandwidth or am I bottlenecked by cat-5e or 1-Gigabit LAN ports on my router? If the answer is "Potentially yes", how do I test it?

Not even close. Wifi like to tell many lies the biggest is they add transmit and receive speed. This would be like calling a ethernet cable 2gbit. Wifi is half duplex so only 1 device can transmit at a time so you can not have both at the same time. Ethernet actually can has 2gbit of bandwidth at one instance even though nobody every calls it that.

Next to get the 1200 number wifi6 uses a very dense data encoding called Qam1024. This work only for fairly short distances. It most times only works in the same room.

Maybe if you are lucky you get 600mbps. I don't know how much data a quest2 can even use. Most times you only need high data rates for downloading big games.

Probably no, 1200 is more a theoretical value of speed the hardware could transfer. The Lan ports are wired and usually faster and more stable than wifi, even 1200 ones.
You can see the actual speed in windows itself, within the properties of the wifi connection or windows task manager performance tab

And even if the WiFi performance were "1200mbps" (it isn't, probably not even half that)...there is zero user perceptible difference between 1200mbps and 1000mbps(gigabit).

This is like comparing 2 cars.
One with a top speed of 140mph, and the other with a top speed of 155mph.
At the track, on a perfect day, in perfect conditions....maybe.

Well, I am trying to make conditions as perfect as possible) I have seen lower latency and significant increase in stability upgrading from good wi-fi 5 router (which is rated 866 mbps) to good wi-fi 6 router, and if this increase was so noticeable even with additional 134 mbps, getting these extra 200 mbps would be really nice)

Wired via good quality Cat5e completely trumps any WiFi.
 
I doubt he can use a ethernet cable with a VR headset but I suspect this is mostly the standard people think bigger numbers are better and convince themselves that the money they spent got them something with no science to back it. I don't know how much bandwidth a VR headset uses but they would not sell many of everyone had to have a top end router that costs as much as the headset to use it.

If you read my question carefully, you'd see that ethernet cable mentioned is between a PC and a router, not headset. Router was a gift and it costs less than half of the headset.
You do not need a good router to use this headset, in fact, you don't need any network at all if you only play standalone single player games. Fast connection is only needed to play PCVR games on Quest and it can use up to 3 Gbps bandwidth via cable, so there is plenty of headroom for wi-fi improvement. Having a good router does improve stability and therefore allows to push bitrate higher (which reduces compression artifacts) before connection becomes unstable again. This was proven by multiple users, reviews and Oculus themselves, and it was noticeable even for me. Science(or math, I'd say) behind that is not hard and it corresponds with real-life results.
Please read questions carefully and make sure you know what you are talking about before replying.
 
I did read your question carefully and clearly told you that you are not going to get anywhere close to 1200. This is even if you buy the $700 routers that have numbers of claiming 16gbit the quest2 wifi is the bottleneck.

User reviews are OPINIONS not facts and you are talking about subjective things that have no way to quantify them.

You can check the facts I gave you very easily just learn how wifi data is encoded rather than reading garbage from users who have no clue. When you can come back and explain why many wifi6 devices only run 80mhz rather than 160mhz then maybe your opinion would slightly matter.
