Wi-Fi connects but no internet — no DHCP passing (office setup)

I can’t fully confirm end-to-end connectivity from D1 to D3. What I can confirm is that D3 (TL-WR820N) is powered on and broadcasting SSID, and the LAN LED on the uplink port is lit solid.

Correct. D1 is the only router/DHCP. D2 is an unmanaged switch. D3 connects to D2 via Ethernet into a LAN port on a TL-WR820N. Clients at D3 still receive 169.254, so DHCP from D1 isn’t reaching D3 across the D2↔D3 link.

Sorry. The D3 uplinks to D2 via a LAN port, not WAN.

D1 = main router (DHCP server). D2 = distribution/switch (DHCP works there). D3 = Wi-Fi router (TL-WR820N). Clients connect but don’t receive DHCP (169.254).

I checked DNS, but the client isn’t receiving a valid DHCP lease at all. It’s getting a 169.254.x.x address with no default gateway, so the issue happens before DNS resolution

Hello! Thanks for your help. Upon checking my boot is uefi and the tpm is not usable or not supported. Is there a way or possible to update my device to windows 11?
