I have a good old Dir-825 that was flashed with OpenWrt since 2014. Later used as a WiFi Repeater and recently as an ethernet connected AP only to discover I don't really know how to configure WiFi Vlan after watching countless video and browsing.
Currently running the latest 21.0 Firmware, dnsmasq and firewall are disabled.
Ubiquiti ERX Router
1.1 ETH0 connects to Modem
1.2 ETH3 connects to Unmanaged switch (may upgrade later to a managed one) | PVID = 1 | VID =
1.3 ETH4 connects to a Unifi AP. | PVID = 1 | VID =
HomeNet is on 1, Guest Net is on 6, IOT Net is on 7
A LAN cable from the Switch goes to the DIR-825 Lan port. Interfaces configured below and successfully gets the correct IP subnet. Interface and VLANs config:
My goal is simply for the DIR-825 to act as an AP with HomeNet SSID, Guest SSID, IOT SSID. The remaining 3 LAN port to be HomeNet. Also, how can I use the WAN port instead of LAN1 as the bridge? Future plan may include wiring another AP to LAN 4.
Have you validated that the ER-X is configured properly for VLANs using a wired computer? You can do this with its built-in switch or with the dumb AP switch to create access ports for each of the networks.
Is your ER-X running OpenWrt or EdgeOS? We'll look at that config next, but first...
From the dumb AP, please copy the output of the following commands and post it here using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:
And then change the proto for these to none. Your dumb AP does not need to have addresses on the extra networks, only the one that is used for managing the device (which I am presuming is lan (192.168.3.0/24)
Also, it should go without saying that your dumb AP must be connected to eth3 or eth4 on the ER-X.
And finally, double check that the logical port 3 on the dumb AP actually corresponds to the port you are using to connect back to the router. It is not uncommon for the port numbers on the case to be different than the logical port numbers within the configuration. From your image in the first post, it looks like that is fine, but verify that the port with the link established does indeed match the port that you've got your VLANs setup on.
If you run brctl show, you should see the wired and wireless interfaces as bridge members.
root@OpenWrt:~# brctl show
bridge name bridge id STP enabled interfaces
br-lan 7fff.909a4a96c58a no wlan1
br-guest 7fff.909a4a96c58a no eth0.4
br-test 7fff.909a4a96c58a no wlan1-2
Thank you, its now working correctly.
Indeed as I doubted there was no connection between the Guest/IoT and the Bridged Lan.
Thank you a lot and an opportunity for me to try the command line config also.
