The eero Outdoor 7 is a weatherproof Wi-Fi 7 access point that eero rates IP66 and tests from -40 to 131 degrees Fahrenheit, and it connects to the rest of the network through a single 2.5 Gigabit Ethernet port that also carries its power. That single cable explains most drops. The Outdoor 7 needs power over Ethernet at the 802.3at, or PoE+, level; eero says ordinary 802.3af PoE does not supply enough, and Tom's Guide's review makes the same point.
The checks in more detail
A switch port, injector or cable that is marginal will let the unit power up and then reset when the radios work hard, so the signal seems to drop at busy times. Check the eero app first: open the Outdoor 7 under Network, look at its status and uptime, and note whether it is offline, restarting or just slow. A unit that restarts often has a power or cable fault; a unit that stays online while devices leave is a radio or placement problem.
Outdoor placement matters as much as power. Mount it where it can see the yard, not behind a metal soffit or beside a brick chimney, and keep it clear of dense hedges, since wet foliage absorbs Wi-Fi. Devices that wander to its edge cling to it and then fall off, so shorten the distance by moving the unit or by adding a node, which the eero app can help you judge from the signal readings.
A cable run longer than 100 meters, a cheap or damaged patch cable and an outdoor joint without a weatherproof connector all cause intermittent power. Use outdoor-rated cable, keep the connector dry and test with a short known-good cable to a PoE+ source. Update the eero firmware in the app, which installs overnight, and restart the whole network in order, modem, gateway, then the Outdoor 7. If drops continue with a good cable and a PoE+ source, contact eero support with the unit's uptime figures.

A PoE source below 802.3at
What separates it The unit restarts under load
How to confirm Use a PoE+ injector, switch or the eero PoE adapter
- 2
A damaged or long cable
What separates it Drops come and go
How to confirm Test with a short outdoor-rated cable
- 3
A poor mounting position
What separates it Devices fall off at the edge
How to confirm Move it or add a node
- 4
Wet foliage or metal nearby
What separates it The signal is weak at times
How to confirm Clear the line of sight
- 5
Old firmware
What separates it Odd behavior after a long time
How to confirm Let the app update the network
Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether the unit shows restarts in the eero app
- The PoE source and its rating
- The cable length and type
- Where it is mounted and which devices drop

Model-specific
What is true of this model and not of its siblings
- One cable
- Power and data share the 2.5 Gigabit port.
- IP66
- Dust and rain tight, not for submersion.
Stop boundary
When this stops being a self-service repair
- !If drops continue with PoE+ and a good cable, contact eero support with the uptime log
- !If the connector is wet or corroded, replace it
- !Use an electrician for outdoor power

Why does my eero Outdoor 7 keep dropping?+
Usually power or cable, then placement.
Does it need PoE+?+
Yes, 802.3at or better.
Does rain affect it?+
It is IP66, but wet foliage weakens signal.
