The T3U Nano (and also similar USB Wi-Fi adapters) do not support this.

And even if it was supported (for example some Wi-Fi 7 M.2/PCIe cards can do it), other users have reported that when they hooked up their Quest devices to Hotspots that are based on Wi-Fi client adapters they ended up with really low speeds.

I think you would be better off with a separate Wi-Fi Access Point that is connected to the PC via Gigabit Ethernet and then share the Wi-Fi connection to the PC Ethernet port via the "Internet Connection Sharing" feature of Windows.

I see

i don't have any other option to connect to internet, i have to use wifi 2.4GHz

although is it possible if i have two wifi key, to use one for the connection to wifi, and another for the hotspot ?

What I meant is that you use the T3U Nano to connect your PC to the Internet via 2.4 GHz as you already do, but then share that Internet connection to the PCs Ethernet port to which you connect a 5 GHz Wi-Fi Access Point to which you then connect the Quest.

That should be possible, but as I mentioned in my previous post other people have tried before to connect their Quest to such a Hotspot and were disappointed by slow speeds. If you search the forum you might be able to find posts about it.

i have another wifi key somewhere, i'll try tomorrow, and i will assume that the low speed other people had was because the two keys were on the same USB controller, therefore dividing USB speed

but won't having two USB wifi key cause issue, won't the two try to connect on the same wifi, and won't the two try to crate the same hotspot ?

No and No.

The two Wi-Fi adapters would only both connect to the same Wi-Fi if you enter the Wi-Fi password for both of them and have both set to "Connect automatically".

I see, i though that it was windows who managed wifi connection, okay then i'll try that tomorrow
