You won't be able to build a 2400 Mbit/s net throughput WiFi router from a scrap PC and some China WiFi card. But go ahead and try. It will hopefully be instructive.

I prefer to use a real AP.

alright alright i will buy an ap but is there an ap with symmetrical speeds on lan and wlan ? preferably under 200 euros

devices from the lan side take private ips from the isc dhcpv4 server usually. They cant receive non private ips.154 is a public ip which means it can not be used as a private ip at the lan side.

umm.... im quite unsure about what you mean but im quite sure you cant use any other ip except for the private ip range

What could possibly go wrong?  ::)

why dont you enligthen me and tell me what could possibly go wrong?

Wow, high-end scientific project! Keep us updated how things go...

100% sure it's the perfect hardware vendor for your project?

cant tell if thats sarcasm or not...  :-\

thats why (see attachemnt). I need OVER 2.4 Gbps (not to be confused with 2.4ghz i need 2400 mbits per second) on the 5ghz band (ON ONE BAND NOT THE SUM UP).

Yeah, you will NOT get that. ;D ;D ;D

why not? what do you mean my man?

Theory vrs real-world application. Have a look for example https://www.increasebroadbandspeed.co.uk/realistic-speeds-wi-fi-5-and-wi-fi-6
Your requirement of over 2.4 Gbps wireless bandwidth and your insistence on achieving it via a consumer Wifi card being put in AP mode is what is making people telling you that is not yet possible to see a way to achieve it.
And this is for the practical side of the hardware.

Then it comes to where you've been told various times that (and I quote)  : 
"But fact is - there is no card that will turn your OPNsense into an AP capable of that. There are hardly any cards that work as an AP at all. OPNsense and FreeBSD have poor support for infrastructure mode, period."

So OPN or not, you can't reach your bandwidth target with a cheap card you want to use.
Then I assume you will be using OPN + OpenWRT somehow (quote) :
"OR have them both. One as firewall (opn) and the other as wifi ap"

Let us know how it goes.

FINALLY someone that gets it. As opnsense doesnt work with pcie cards i will buy the 3000mbps card and run opnse as firewall and openwrt as ap along in proxmox!!!!!! thanks coockie you are always the best edit: mt7916 asia rf npd is wifi 6e so yeah :)

2021 article?

why not? what do you mean my man?

But why build an AP from a mini PC when you can have a cheaper and more reliable AP from a reputable vendor?

The hAP-ax2 is less then 100 $/€ and they have a "light" version that's less than 60 €/$. I would not want to waste my time trying to build an AP from scratch, but you do you.

And again: Mikrotik is far from the only choice.

thats why (see attachemnt). I need OVER 2.4 Gbps (not to be confused with 2.4ghz i need 2400 mbits per second) on the 5ghz band (ON ONE BAND NOT THE SUM UP). Wifi cards offer these speeds at really low prices to be honest. check mt7916npd asiarf for example.Its supported for ap by openwrt. I got wifi 6 over 2.4 gbps on 5ghz band and its price is 40 euros and with transportation fees its 60!edit: forgot the attachment lol

OK, WiFi 6 theoretically can do that - granted.

But fact is - there is no card that will turn your OPNsense into an AP capable of that. There are hardly any cards that work as an AP at all. OPNsense and FreeBSD have poor support for infrastructure mode, period.

If you insist on turning your mini PC into an AP instead of just buying an AP, most probably the best path is to switch from OPNsense to OpenWRT.

OR have them both. One as firewall (opn) and the other as wifi ap

2.4 GHz - not 2.4 Gbps ...

Ohhhh damn. Thats what yall thought didnt you. No i actually meant 2.4 gbps as of 2400 mbps wireless as of 2400 mbits per second my man. I want dual band or triband if yall ask about frequency but no lol i didnt mean 2.4 ghz

Uh. You will not get anything near 2.5 Gbps over wifi. This debate is getting increasingly absurd.

What do you mean? There are loads of over 2.4 gbps wifi cards routers and even aps. I dont get what you mean.

in reply to anyone telling me to buy a router or ap i will probably not. The reason is because almost none under 200 euros ap/router has a 2.5 gbps port which i need to transport the data at the same speed as my firewall can. So just buying a wiif pcie card and making it act as an ap inside the mini pc not only i dont save money but i gain speed too. If someone of you has ever run openwrt can you make a wifi ap interface easily inside a virrtual environmnent because many have told me that its not suggested.

i already got a mini pc bro i need a pcie card to make it act as a wifi ap

I use an ARM device with wifi stick in access point mode running linux (bridged with eth0). I have one opnsense with wifi as WAN, but that's a different piece of cake.

wifi as an access point on opnsense directly: I don't think you will find a single thread on this forum supporting this setup, not to speak of wifi 6

https://wiki.freebsd.org/dev

https://www.freebsd.org/releases/14.0R/hardware/

https://docs.netgate.com/pfsense/en/latest/wireless/hardware.html

i guess then i will have to stick either with openwrt in proxmox that is never been experimented for wifi purposes or buy an external consumer router

Hey cookkie, is there a popular card out there that someone from the forum has used and made a topic about it ?
