Your Eero Pro 7 shows all blue lights but nothing loads. Or the eero app says everything's healthy and the internet is still down. Or some devices connect while others sit there spinning. Whatever the symptom looks like, the fix usually takes five minutes once you know what to check first.
Unplug the modem and the Eero Pro 7 gateway from power. Wait a full 60 seconds with both unplugged. Plug the modem back in and let it fully boot up, typically two to three minutes until its lights settle. Then plug the eero back in and give it 90 seconds. This modem-then-eero order matters because the eero needs to negotiate a fresh WAN lease with a fully online modem. Most "no internet" cases resolve right here.
If you're still offline after that, here's what's likely going on and how to work through it.
Rule Out an ISP Outage
Before touching any settings, confirm it's not your provider. Turn off Wi-Fi on your phone so it uses cellular data, then check your ISP's status page or Downdetector. If there's an outage in your area, nothing you do to the eero will fix it.
A surprisingly large number of "router is broken" situations turn out to be ISP problems. Save yourself the headache and check this first.
What the Eero App Tells You About the Gateway
Open the eero app and look at the gateway tile at the top of the screen. If it's red or amber, tap it for diagnostic details. You'll usually see one of a few specific messages. "Cable connection issue" means the ethernet cable between your modem and eero is loose or bad. "WAN authentication failed" means the modem isn't handing off an IP. "Internal error" points to a firmware glitch that a restart will clear.
The app itself offers one-tap fix links for most of these alerts. If the gateway tile is green and you still have no internet, the problem is somewhere else.
Check the WAN Cable and Port
The Eero Pro 7 has two auto-sensing 5 GbE ports. The cable between your modem and the eero needs to be at least Cat 5e, and Cat 6 is better if you're on a gigabit or faster internet plan. A worn-out Cat 5 cable can cause the port to negotiate a link speed but fail to pass traffic consistently.
Swap the WAN cable with a known-good Cat 6 and see if the eero renegotiates the link within 30 seconds. If you have a multi-gig plan, Cat 6 minimum is non-negotiable.
DNS Is the Usual Suspect for "Connected, No Internet"
When devices show a Wi-Fi connection but nothing loads, DNS is the most likely culprit. The eero's default DNS goes through your ISP, and ISP DNS servers can get flaky or slow without warning. Open the eero app, tap Settings, then Network Settings, then DNS. Switch to Custom and enter 1.1.1.1 for Cloudflare and 8.8.8.8 for Google.
Save the change and give devices a minute to reconnect. Public DNS bypasses whatever broken resolver the eero was using and usually restores web access immediately.
If You Enabled WPA3, Try Disabling It
WPA3 on the Eero Pro 7 isn't on by default. It's an opt-in feature you turn on in eero Labs under the Discover tab. If you enabled it, some older clients, especially Wi-Fi 5 and early Wi-Fi 6 devices, can connect to the network but fail to pass traffic. The symptom looks exactly like "no internet" on those specific devices.
Open the eero app, go to Discover, tap eero Labs, and toggle WPA3 off. The network drops back to WPA2/WPA3 transitional mode and those affected devices should start working again.
Stalled Firmware Updates Can Break Routing
Eero routers update firmware automatically through the app. There's no manual download option. Most updates happen overnight without any issue, but occasionally an update stalls midway. When that happens, the router can lose its routing table for an hour or more while it waits for the update to finish or time out.
Open the eero app, tap Settings, and look at Software Version. If it says "Updating" and has been stuck there for more than two hours, power-cycle the gateway eero, unplug it, wait 60 seconds, plug it back in. Only power-cycle the gateway, not the satellites. The update will either resume cleanly or fail and restart the process.
Restart Satellites One at a Time
If you have multiple Eero Pro 7 nodes and only some parts of your house have internet, a TrueMesh routing loop might be the cause. Occasionally a satellite tries to route traffic through itself instead of the gateway, and devices connected to that satellite lose internet.
Unplug each satellite (not the gateway) one at a time, wait 30 seconds, plug it back in, and wait about 90 seconds for it to rejoin the mesh. Do them individually, not all at once. This forces the mesh to recalculate its routing paths and often clears the loop.
When to Factory Reset the Gateway
If none of the above steps worked, a factory reset is your last shot before calling support. This wipes your network settings, so plan for 20 minutes and have your ISP credentials handy.
On the back of the gateway eero, hold the reset button for about 15 seconds until the LED flashes red rapidly. Release it. The gateway reboots and returns to factory state. You only need to reset the gateway, the satellites will rejoin automatically once you set up the new network through the app. Run through the setup process fresh and test internet after the initial configuration completes.
