Wireless clients not receiving IP addresses

Hi,
I have a RE650 configured as a OpenWRT access point (as per https://openwrt.org/docs/guide-user/network/wifi/dumbap#wireless_access_pointdumb_access_pointdumb_ap) with an Apple Airport Time Capsule acting as my main router which is in turn connected to by cable modem.

Both are configured with the same Wifi SSID and password and connected via LAN cable and the Airport Time Capsule is acting as a DHCP server.

Some of my devices refuse to get IP addresses when connecting to the RE650 as per the screenshot below which I can't seem to explain.

My config is below with the relevant services disabled as per the https://openwrt.org/docs/guide-user/network/wifi/dumbap#wireless_access_pointdumb_access_pointdumb_ap guide.

This (the list) is what it looks like, when your RE650 isn't the dhcp provider.

You can always link the MACs to a device, by using fping or /etc/ethers.

You should still receive IPs though.
Check if you need relayd.

Thank you @frollic - I am using the same lan and subnet for both devices - so my assumption is that relayd is not needed.

sounds a bit similar: Not getting IP Address from OpenWrt Router when connected through WiFi Range Extender

I have narrowed this down to a HP Deskjet 3630 Wifi device which seems to be the only device that will not obtain an IP address from the RE650 running OpenWrt.

In order to remove any issues with the Apple Time Capsule, I have replaced that with a OpenWrt router (Compute Module 4 IoT Router Carrier Board) which acts a DHCP server.

could have put the DHCP on the RE650.

True, however I am hoping for a setup with multiple RE650's acting as access points configured for a single SSID with a single OpenWRT router provider DHCP on a single subnet.

I assume this is possible but happy to be corrected !

Sure, I've done it, but using routers as APs with 802.11r.
