Your printer used to connect without a second thought. Now the print queue sits in limbo, the setup app spins forever, or your laptop acts like the printer doesn't exist. The Eero Max 7 is a beast of a mesh router with Wi-Fi 7 and 10GbE ports, but some of its defaults and the way it handles older WiFi clients can make printer pairing a headache until you know the specific tricks.
Here's the fastest two-part move that resolves most printer issues: make sure WPA3 is off (it's opt-in via eero Labs, not on by default), then bring the printer within a few feet of the gateway eero for the initial setup. Open the Eero app, tap Discover then eero Labs, and confirm WPA3 shows as Off. Move the printer into the same room as the gateway, run the printer's WiFi setup wizard, then move it back to its permanent spot once it's paired.
If that doesn't do it, the fixes below cover the rest of what's going on.
Start With the WiFi Security Setting
The Eero Max 7 ships with WPA2/WPA3 transitional as the factory default, so WPA3 isn't on unless you explicitly flipped that toggle in eero Labs. If you did turn it on at some point, most printers made before 2022 simply can't authenticate. Open the Eero app, tap Discover, eero Labs, and toggle WPA3 off.
Once the printer is paired and working, you can turn WPA3 back on if you want. Most modern phones and laptops will handle the mixed-mode negotiation fine, but the printer will keep using the older protocol it already agreed to.
The 2.4 GHz Problem and How to Work Around It
Plenty of printers still only support 2.4 GHz WiFi. The Eero Max 7 broadcasts a single SSID for all bands and steers your phone to whichever frequency makes sense at the moment, usually 5 GHz or even 6 GHz. That means your phone might not see the same network the printer is trying to join during setup.
The Eero app doesn't let you split bands manually. The workaround is simple: use the printer manufacturer's official app (HP Smart, Canon PRINT, Epson iPrint, Brother iPrint&Scan, etc.) to handle the pairing. Those apps are designed to negotiate the band-switching automatically. Avoid generic printer utilities that don't know how to talk to the mesh.
If the manufacturer's app still fails, set the printer up temporarily with a phone that's physically standing right next to the gateway eero. The band-steering algorithm tends to keep clients on 2.4 GHz when signal from the gateway is very strong.
Check the Guest Network
This one trips people up more than you'd expect. If your printer is on the main network but your phone is connected to the guest network, they can't see each other at all. The Eero guest network is fully isolated from the main network. Open the Eero app, tap the device list, and check which network each device is on.
Move your phone and the printer to the same network. If you need the printer on the guest network (some setups put IoT devices there), you'll have to use a different approach like AirPlay or a direct USB connection, because mDNS discovery won't cross the isolation boundary.
Update the Printer's Firmware
Many printers shipped with WiFi firmware written years before Wi-Fi 6E or Wi-Fi 7 existed. If your printer worked fine on an old router but refuses to pair with the Eero Max 7, outdated firmware is a strong suspect. Check the printer manufacturer's support site for the latest firmware and update via USB cable if the WiFi setup isn't working yet.
After the firmware update, try the WiFi pairing process again from scratch. This often fixes the handshake issues that newer mesh routers expose in older clients.
Set a Static IP Once the Printer Is Connected
Once you get the printer paired and talking to the network, give it a static DHCP reservation so it always gets the same IP. This makes AirPrint and network discovery much more reliable over time. Open the Eero app, tap Settings, Network Settings, Reservations & Port Forwarding, and add a reservation using the printer's MAC address.
Without a static reservation, a reboot of the mesh could hand the printer a different IP, and your laptop might keep trying to reach the old address. That's a common cause of the "printer is on but I can't print to it" problem.
Force-Refresh Discovery on Your Device
If the printer shows as connected in the Eero app but your phone or Mac can't find it for AirPrint, the issue is mDNS propagation across the mesh. Try toggling WiFi off and back on your device. On a Mac, open System Settings, Printers & Scanners, remove the printer, and add it again.
This forces your device to re-broadcast an mDNS query, which often picks up printers that were there but not being advertised correctly.
Cycle the Gateway Eero
Sometimes the mDNS relay between satellites gets stale. A full power cycle of the gateway eero clears that up. Unplug the gateway unit, wait 60 seconds, and plug it back in. Don't bother restarting the satellites, just let the mesh rebuild around the gateway.
Wait about five minutes for everything to stabilize, then try printer discovery again.
Reset the Printer's Network Configuration
If the printer has been through multiple failed pairing attempts, its WiFi memory might be corrupted with bad credentials or partial handshake data. Reset only the network settings, look for "Restore Network Defaults" or "Reset LAN Settings" in the printer's menu. Don't do a full factory reset unless you're prepared to reconfigure everything else.
Once the network settings are cleared, run the printer's WiFi setup wizard from scratch with the printer right next to the gateway eero.
One Last Thing About the Eero Max 7
The Eero Max 7's 10GbE ports are fantastic for multi-gig fiber plans, but they don't change anything about printer connectivity. The printer is connecting over WiFi, not Ethernet. The 2.5GbE ports on the back are for wired backhaul between nodes or connecting a wired device directly. If your printer has an Ethernet port, plugging it directly into one of the Eero's LAN ports using Cat 6a or better cable is actually the most reliable option, it bypasses WiFi issues entirely.
Printers with wired Ethernet don't need to worry about band-steering, mDNS across mesh, or WPA3 compatibility. If your printer supports wired and wireless, give wired a try.
