Your Eero 6+ shows a solid white LED in the app but websites won't load. Or the gateway eero says everything's fine, yet streaming stops and buffering starts. Or every device just drops offline at once. This is fixable within a few minutes if you follow the right order.
Start with the modem-first power cycle. Unplug your modem from the wall. Unplug the Eero 6+ gateway from the wall. Wait a full 60 seconds with both unplugged. Plug the modem back in and wait until its online light is solid (usually 2 to 3 minutes). Then plug the eero gateway back in and wait another 90 seconds. Check for internet. This order matters because the eero needs to see a fully authenticated modem before it can negotiate its WAN connection. If you reversed it, the eero may cache a no-WAN state and won't fix itself until the next reboot.
If that didn't get you back online, here's what else could be wrong and how to fix each cause.
Rule Out an ISP Outage First
Before touching the router, confirm your ISP isn't down. Turn off Wi-Fi on your phone and check your ISP's status page or Downdetector using cellular data. A surprising number of "router doesn't work" cases turn out to be regional outages that no amount of resetting will fix. If your ISP shows an outage in your area, just wait it out.
Check the Gateway Status in the Eero App
The eero app is the only way to manage this router, there's no web UI. Open the app and tap your network at the top. Look at the gateway tile. If it shows red or amber, tap it for diagnostic details. Common messages include "Cable connection issue" (the Ethernet cable between modem and eero is loose or bad), "WAN authentication failed" (the modem isn't passing traffic), or "Internal error" (a firmware glitch). The app often offers a one-tap fix for these alerts, so try that first.
Check the Ethernet Cable Between Modem and Eero
The Eero 6+ has two Gigabit Ethernet ports. One connects to your modem, one to a wired device. If that WAN cable is worn, damaged, or just barely seated, the Gigabit handshake can fail. The modem may show a link light, but no traffic passes through. Swap the WAN cable with a known-good Cat 5e or Cat 6 cable. The eero renegotiates within about 30 seconds. If you have internet faster than 1 Gbps, use Cat 6 minimum, though the Eero 6+ caps out at 1 Gbps anyway.
Switch DNS to Public Servers in the Eero App
If devices show "connected, no internet" but won't load anything, DNS is the usual culprit. Open the eero app, tap Settings, then Network Settings, then DNS. Switch from Automatic to Custom and enter 1.1.1.1 (Cloudflare) and 8.8.8.8 (Google). Save. Devices reconnect and DNS queries now bypass whatever broken DNS the eero was using. This fix is quick and reversible, you can switch back to automatic anytime.
If You Enabled WPA3, Disable It
WPA3 on the Eero 6+ is an opt-in feature tucked inside eero Labs, not enabled by default. If you turned it on, some older devices, particularly printers and IoT gadgets, may connect to Wi-Fi but fail to pass traffic, giving you a "connected, no internet" symptom. Open the eero app, tap Discover, then eero Labs, and toggle WPA3 off. The network reverts to WPA2/WPA3 transitional, and those devices should start working again. In my experience, this is one of the most overlooked causes of no-internet issues on eero networks.
Reboot Each Eero Node, Not Just the Gateway
If some devices work but others don't, the problem is likely a satellite node. The Eero 6+ uses TrueMesh to route traffic automatically, and occasionally a satellite gets stuck in a routing loop. Unplug each satellite node one at a time. Wait 30 seconds, then plug it back in. Wait 90 seconds for it to rejoin the mesh before moving to the next satellite. Don't reboot the gateway first, fix the satellites individually.
Check for a Stalled Firmware Update
Eero updates firmware automatically through the app, you don't download anything manually. Open the eero app, tap Settings, then Software Version. If it says "Updating" for more than two hours, the update stalled. Power-cycle the gateway eero (unplug, wait 60 seconds, plug back in). That either finishes the update or resets the attempt so it tries again cleanly. Don't unplug satellites while the gateway is updating.
The single SSID on the Eero 6+ means your phone might lock onto the 2.4 GHz band in a dead zone, even when 5 GHz is available elsewhere in the house. If you have an iOS device, go to Settings > Wi-Fi, tap the info icon next to your network, and toggle Private Wi-Fi Address temporarily. On Android, go to Wi-Fi settings, tap your network, and toggle MAC address type to "Device MAC." Then reconnect. This doesn't fix the eero itself, but it gets individual devices unstuck from a bad band.
Factory Reset the Gateway Eero
If nothing else has worked, factory reset the gateway eero. Hold the reset button on the back for about 15 seconds until the LED flashes red rapidly. Release. The eero reboots, flashes white during boot, then glows blue when ready for setup. You only need to reset the gateway, satellites rejoin the mesh automatically once you reconfigure the gateway in the app. Have your ISP credentials handy and plan about 20 minutes for this process.
A factory reset is the nuclear option but it clears routing tables, DNS caches, and any corrupted configuration data that a power cycle won't touch.
