I have an HP Printer LaserJet M102w that I am trying to connect it to my openwrt router wifi. Wifi connection takes place and printer shows connected to wifi, however the printer still gets an APIPA address after all and not IP address from the router's IP address range.[How-To-Updated 2021] Installing AdGuardHome on OpenWrt [Manual and opkg method] - Community Builds, Projects & Packages - OpenWrt Forum
Any help to figure out why openwrt is not providing an IP address to my printer would be appreciated.

You run openwrt dhcp or agh dhcp?using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

opkg list-installed adguardhome - returns nothing
Don’t use PSK mixed (wpa1/wpa2). Just use wpa2.
And similarly don’t use sae-mixed. Use either wpa2 or wpa3. Mixed mode often causes problems.
And delete all these rules. These should never be exposed to the internet. If you need remote access, setup a vpn.

Undo the changes you did to the DNS/DHCP configuration, try if it works, then add them back one by one, and see which one causes the issue.
I have just tried resetting the openwrt to default and just enabled wifi on it with no password. Still my printer gets an APIPA ip address.
However if I connect my printer to my phone hotspot, I can connect to it and it gets proper IP address
So there must be something wrong with the DHCP on openwrt.

Run tcpdump and capture dhcp request.
Initially what I can see is that there is no DHCP ACK happening if I compare it with another device that connects successfully to the wifi of openwrt
You won't believe it. I downgraded the firmware from OpenWrt 23.05.4, to OpenWrt 23.05.3 and now my printer is taking a proper IP address from the openwrt

Upgrade and check again? You still have not specified if the problem is with OpenWRT or AGH blob dhcpp server.
I reset the router, so it should be back to default dhcp and no AGH involved after reset. So I don't think my issue was with AGH

Please grab dhcp request and renew packets from the device, then upgrade to .4 in place and do that again.

Looked at your capture (wireshark) -
Interesting - this seems a lingering IP address from when I tried to connect the printer to my phone hotspot.

Probably needs wired/wireless in same subnet to feed its special requirements. Or a firmware update.

Yes, the pcap from working side would explain a lot - check the requested address attribute and the response to it. i.e what changed in OpenWRT responses that confuses printer.
The thing is that I have two openwrt linksys routers had the same issue, and they both had the latest firmware. On the one where I downgraded the firmware, the printer was able to get an IP address, while the openwrt linksys router with the latest firmware still has the same issue.
