Following up on this topic.
Installed open wrt on my RPI4 and used my onboard wifi to connect as client. I understand this is not the best connectivity solution but perhaps the best for the RPI. Is there a better alternative to connect as client to camping wifi?
Furthermore I use a WIFI N adapter with internal antenna's. Is there a better alternative with WIFI ac to work with the RPI and open wrt?
Thnx for the help.
I try to make a camping router using Internal and external WiFi, 4G and tethering.
I have a Linksys wireless N dongle (2.4) which is working as should but I want to upgrade to AC with external antenna for more coverage.
Aiming to use the onboard WiFi of my RPI 4b as AP and the USB dongle for connecting to another clients.
I have two questions:
Hope someone can help me with this.
That's what the links above will tell you.
Thnx for the reply.
So if I understand correctly, only the 2.4GHz band works on OpenWRT, and it's essentially a lucky guess whether the 5GHz band of a specific dongle works or not? The Panda Wireless PAU0B is a dongle that can reliably operate on both 2.4GHz and 5.0GHz with OpenWRT, correct?
If that's the case, then this dongle might indeed be the best choice.
Do you mean that the internal WiFi of my RPI 4b is Broadcom and that's the reason why I can't switch the wireless from client to AP mode?
Is there any way to configure or set this up to make it work?
If it's an AC dongle, AC should obviously work.
Not simultaneously.
That's a hw limit of the radio.
b/g should work in AP mode, as described in the wiki, your clients might not support it though.
2.4 GHz has the greatest coverage/range; indoor or outdoor.
No: it has two radios already; they are just weak but both should be working.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

Found this post regarding internal wifi of the RPI, is this the problem I could have?

Did you use ChatGPT before you came here?
No.
Your config is corrupted.
You can try clicking disable, wait for it to take effect, click enable and see if that starts it.
If that fails try restarting the radio itself.
Did you use ChatGPT before you came here?
What is wrong with the config, I don't understand?
Restarted the adapter multiple times already and enabled and disabled the wireless a couple of times, 'OpenWrt' just won't come up.
Your config is corrupted.
Why is my config corrupted, what can I do to fix it?
thnx for the help.
But did you use it?
So, that config tells the radio0 to not be in AP mode but STA mode and it is dangling out there all alone and not in the stanza it should be.
All those single lines I quoted are not supposed to stand alone.
And, again, in your case the last thing OpenWrt sees is 'put radio0 in STA mode'. It's not where it is supposed to be so LuCI cannot edit it.
I'd start over but that is my go to answer most the time with RPis.
Ok, Start over is not a problem. I know what to do. So it is possible to have the onboard wifi in my py act as a AP and the dongle acting as a client?
If so, starting all over is perhaps the best option.
Yes. But the range would work better in reverse.
The deal on USB and RPi:
Pick a port for the dongle and do not move the dongle after it is recognized the first time.
RPIs can get flakey when more than one device already has that USB address.
And physically add it after its first boot or after adding the driver and then rebooting .
I want to use this as camping WiFi in my mobile home. Range from the internal antenna is not as important as connecting to the Camping WiFi.
After reinstalling the whole thing it looks to be working ;).
Thnx for the help, I can now order the WiFi dongle to connect to external WiFi.
The antenna that comes with it is good.
If you would like a recommendation for a good directional for the client:

Thanks! 
Hmmm, seems I am not able to order this Panda dongle from the EU. Think I have to look for another one pffff. any suggestions again?
could this be an option? https://www.amazon.nl/Draadloze-netwerkkaart-wifi-dongle-adapter-wifi-kaart-netwerkadapter/dp/B08DF5HF19/ref=sr_1_2_sspa
RTL is never a good buy, even if things are improving, this is also written in the USB Wi-Fi that work in OpenWrt thread.
I'm lost in this! What would be the best guess (with external antenna):

-ALFA Network AWUS036ACS
