Is there some guide that tells me how to wirelessly create an 2.4Ghz AP that bridges to an existing 5Ghz AP?

I have a 5Ghz only network.. and I have some legacy 2.4Ghz devices that I need to use from time to time.. I will turn on that 2.4G to 5G bridge when I need to use the 2.4G device. the AP SSID from the 2.4G can be different from the 5G

thx

Are you trying to do this on the same device that is responsible for the network as a whole, or on a separate dumb ap or repeater config?

on the same device, the TL-WR902AC.. thx

This should be fairly simple...

let's take a look at your configuration:

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:
grafik
Remember to redact passwords, MAC addresses and any public IP addresses you may have:

ubus call system board
cat /etc/config/network
cat /etc/config/wireless

can I do it with luci? (step by step..) thx

the cli is too much for me.(sorry I am dumb). thx

Yes, but...

  1. we need to understand your current configuration. Looking at the text configs provides the full story really quickly. You'd need to provide a whole ton of screenshots to get the same thing (and it's hard to read and keep track of the configs with screenshots)
  2. Providing the breadcrumbs/step-by-step for the GUI is a lot more work to describe, and more error prone.

Also, getting some familarity with the command line is a good thing.

But... if you can at least give me the text configs I've requested, I may be able to find a guide or documentation that will be useful.

its just a device with fresh settings, default all wifi off, etc

In that case, typically your lan is setup with a bridge device (br-lan). You simply need to go into each radio, setup an SSID with the same name, encryption type, and password, and then enable it. (don't forget to also set your country code correctly on both radios).

I want a WAN to WAN bridge...

Please elaborate... a wan-to-wan bridge? Can you describe exactly what you are trying to accomplish.

EDIT: rereading your initial post ... are you trying to use the WR902AC to connect to an upstream network wirelessly and then create a 2.4GHz network to which other devices can connect?

Earlier, when I asked if this was the same device responsible for the network as a whole (i.e. the main router), you said it was the same. But it seems maybe the communication wasn't quite precise enough.

So... maybe the best plan is to draw a diagram of your intended outcome. This can be a photo of a sketch on paper -- it doesn't need to be too complicated.

You can use the guides for relayd, WDS, or mesh wifi repeaters; it does not matter that you are repeating on a different band.

Aside from the fact that the 2.4 and 5.4 GHz cannot connect via Wireless. Assuming the OP knows this simple point of Physics, it may help to clarify and elaborate, as psherman already noted.

If you mean the 2.4 and 5.4 GHz network connect to the same Wired network or VLAN - you simply browse to LuCI and add the 5.4 to the same network as the 2.4 GHz SSID.

This is done under the AP configuration on the Wireless menu.

They can use different SSIDs.

If you mean something different than outlined - feel free to elaborate to clarify your desire.
