Sorry for spam, my reply got cut off
Okay, assuming that I change to wifi 7 hardware for my desktop, what kinda wifi speed can I roughly expect. I’m only around 5metres away from the 810ev router
Another thing is, I thought the spec for 5ghz on the 810ev router is up to 5760mbps, how come I’m only getting 1gbps ah? The spec for 5ghz is for wifi 7 issit?
You need to understand the marketing vs reality.
Vendor Spec:

- BE22000 Tri-Band WiFi: 11520 Mbps (6 GHz, EHT320) + 8640 Mbps (5 GHz, EHT240) + 1376 Mbps (2.4 GHz, EHT40).†△
Reality -- usually you can not get EHT240 to work under the 5GHz band, you will only get EHT160 (160MHz channel bandwidth). The max PHY speed will be 5764 Mbps (4 x 4 160MHz channel width, 4096 QAM).
WiFi 7 clients are only up to 2 x 2. So you will only get up to 2882 Mbps PHY speed with 4096 QAM. 4096 QAM is usally achievable at very close range. So in the end you may only get 1024 QAM to work. Then the PHY speed is only up to 2402Mbps, same as good WiFi 6 clients (2 x 2 160MHz channel bandwidth, 1024 QAM).
You can check the PHY connection speed of your computer to see if it is 2882Mbps or 2402Mbps or 1201 Mbps.
Then the real world speed will be lower, usually the real world speed is about 50% to 70% of the PHY connection speed.
Good 2*2 WiFi 6 client will get about 1.4Gbps to 1.8Gbps at about 3m distance, if you get connection speed of 2882Mbps (4096QAM) or 2402Mbps (1024 QAM).
If you only get connection speed of 1201Mbps, then the real world speed will be about 600Mbps to 800Mbps.
2x2 WiFi 7 clients on the
6GHz band may be much faster because of EHT320 (320MHz channel bandwidth, 4096 QAM). Max PHY speed can go up to 5764 Mbps and real world close range speed can go above 3Gbps. However, Singapore only approved the lower 6GHz band so you may not be able to get EHT320 working. EHT240 should be achievable at close range. In that case, you should be able to get above 2Gbps WiFi speed at close range.
For desktop to enjoy full WiFi 7 benefits like MLO, you have to get WiFi 7 adapter and
wait for the release of Windows 11 24H2.
