Printer not getting IP on Wi‑Fi or Ethernet — DHCP, APIPA 169.254, self‑assigned IP (HP, Epson, Canon, Brother)

Technician

Hey! Let’s get your network printer back online. When a printer won’t obtain an IP address from DHCP and shows 169.254.x.x (APIPA) or Self‑assigned IP, we check: router’s DHCP server scope, Wi‑Fi password/authentication (WPA2/WPA3), MAC filtering, and whether the printer supports the selected band (2.4 GHz vs 5 GHz). Tell me the brand (HP/Epson/Canon/Brother), connection type (Wi‑Fi or Ethernet), and what the IP shows on the Network Status page.

Customer

It’s an HP LaserJet on Wi‑Fi. The printer reports Invalid IP / 169.254.83.21. Router is an ASUS. Phones connect fine. Windows says “printer offline” and the HP app can’t find it.

Technician

Got it. A 169.254 address means the printer never received a lease from the router — Windows calls this “self‑assigned IP”. Common causes:
• Router DHCP server off, out of leases, or wrong subnet/VLAN.
• Wi‑Fi using WPA3‑only, 802.11ax‑only (Wi‑Fi 6 only), or client isolation (AP isolation) that blocks discovery.
• Hidden SSID, mixed 2.4/5 GHz with separate passwords, or band steering confusing legacy printers.
• Static IP set on printer that doesn’t match your subnet (e.g., 192.168.0.x vs router 192.168.1.x).
Plan: verify router DHCP, reset the printer’s network settings, join the correct SSID, then set a DHCP reservation or static IP to keep it stable.

Customer

DHCP is on. Scope 192.168.50.2–.254. The printer was previously static at 192.168.1.50 on our old router. Could that be it?

Technician

Yes — that static IP is on a different subnet. Do this:
1) Factory reset network only (not full reset): from the printer’s control panel open Network → Restore Network Defaults (HP) or hold Wireless + Cancel for 5 sec depending on model.
2) Reconnect to Wi‑Fi: pick the 2.4 GHz SSID if offered, enter the correct password (PSK), ensure security is WPA2‑PSK/AES or mixed WPA2/WPA3.
3) Check IP: print a Network Configuration page — you should see a 192.168.50.x DHCP address and valid gateway/DNS.
If that works, we’ll add a DHCP reservation so the IP doesn’t change.

Customer

After network restore it joined Wi‑Fi and grabbed 192.168.50.68. I can open the Embedded Web Server (EWS). Should I leave it DHCP or set static?

Technician

Prefer a DHCP reservation at the router (bind MAC → IP). It avoids conflicts and keeps DNS/route info correct. Steps (generic): Router → LAN → DHCP Server → Add reservation for the printer’s MAC address, e.g., reserve 192.168.50.68 or a free address outside the dynamic pool. If your router can’t reserve, set a static IP on the printer within the subnet (IP, subnet mask, default gateway, and DNS — usually the router IP).

Customer

Makes sense. Windows still shows the queue as offline though. Do I need to re‑add it?

Technician

If the IP changed, re‑add the printer using a reliable protocol:
• Windows 10/11: Settings → Bluetooth & Devices → Printers & scanners → Add device → Add manually → TCP/IP device → enter printer IP → use WSD/IPP or vendor driver (HP Smart, HP Universal Print Driver).
• macOS: System Settings → Printers & Scanners → Add → choose IP tab → enter IP, protocol IPP or AirPrint → pick model. This prevents Bonjour mismatches after DHCP changes.

Customer

What if it happens again? Anything on the router I should tweak?

Technician

Yes — stability checklist:
• Ensure DHCP server is enabled and the lease range has free addresses.
• Disable AP/client isolation (a.k.a. “guest isolation”) on the SSID with printers.
• Keep 2.4 GHz enabled — many printers do not support 5 GHz or WPA3‑only. Use WPA2‑PSK/AES or WPA2/WPA3 mixed.
• Turn off randomized MAC only for the printer (use the physical MAC).
• Update router firmware and the printer’s firmware via EWS.
• Reserve the IP (or set static) and reboot the router after changes.

Customer

We also have a wired Brother. Could a bad Ethernet cause “no IP address assigned”?

Technician

Absolutely. For Ethernet printers that fail DHCP:
• Check link lights; replace the cable and try a different switch port.
• Verify the switch isn’t on a different VLAN without DHCP helper/relay.
• Make sure the printer NIC is set to Auto‑negotiation (not forced 100/Full).
• If the printer still shows 169.254, manually assign a static IP in the correct subnet to test gateway/DNS reachability (ping the router).

Customer

Can you recap the fastest, guaranteed fix if a printer keeps getting APIPA?

Technician

Accepted fix: Restore Network Defaults on the printer → join the correct 2.4 GHz WPA2 SSID → confirm it receives a DHCP lease (not 169.254) → set a DHCP reservation (or static IP) → re‑add the queue using IPP/TCP‑IP and the reserved IP. This resolves 99% of “printer not getting IP address from router” cases.

Customer

Done. It prints from Windows and Mac. Appreciate the deep dive!

Technician

Summary: If your printer won’t get an IP address and shows APIPA 169.254 or Self‑assigned IP, reset network settings, verify router DHCP, reconnect to a supported SSID, then lock a reservation/static IP. Update firmware and disable client isolation for reliable network printing. Need hands‑on help? Open the chat.

Quick answer: the accepted fix

Accepted fix when printer not getting IP address from router (DHCP): restore Network Defaults, reconnect to 2.4 GHz WPA2 Wi‑Fi or Ethernet, confirm a valid DHCP lease, then create a DHCP reservation (or set static IP). Re‑add the printer via IPP/TCP‑IP using the reserved address.

FAQ

Step‑by‑step (Windows 10/11)

1. Print the printer’s Network Configuration page and note the IP (if 169.254, proceed).
2. Open Router → DHCP Server and confirm it’s enabled with free leases.
3. On the printer, Restore Network Defaults and reconnect to the correct SSID (2.4 GHz, WPA2).
4. Re‑add the printer: Settings → Printers & scanners → Add device → Add manually → TCP/IP device using the new IP; install vendor driver if prompted.
5. Create a DHCP reservation for the printer’s MAC so the IP stays fixed.

Step‑by‑step (macOS)

1. Ensure the printer gets a valid DHCP address (not self‑assigned).
2. System Settings → Printers & Scanners → Add → go to IP tab → enter the printer IP with protocol IPP or AirPrint.
3. If discovery fails, disable Wi‑Fi client isolation on the router and keep Mac/printer on the same subnet.
4. Reserve the IP in the router or set a static IP on the printer.
