Quick Answer
Restart both your router/modem and the Alexa device (unplug 30 seconds). Then open the Alexa app → Devices → your Echo → Network → Change, and re-enter your Wi-Fi password. Most connection issues are solved by a simple restart and re-entry of the password.
Common Causes
- Wrong or outdated Wi-Fi password
- Router on a 5GHz-only network (some Echo devices need 2.4GHz)
- Too far from the router
- Router blocked known devices / MAC filtering
- Temporary ISP or router glitch
Step-by-Step Fix
1. Restart Router and Alexa
Unplug the router AND the Alexa device for 30 seconds. Plug router back in, wait 2 minutes, then plug in Alexa.
2. Re-enter Your Wi-Fi Password in the App
Open Alexa app → Devices → Echo & Alexa → your device → Network → Change → select your Wi-Fi → type password → Connect.
3. Use a 2.4GHz Network
Guest or IoT networks on 2.4GHz are more reliable for Echo. If your router is dual-band, make sure 2.4GHz is on.
4. Move Closer to the Router
Test setup within 10 feet of the router, then move the device back.
5. Reset Network Settings
If nothing works, do a factory reset (hold Action button ~20s) and set up fresh.

Recommended Wi-Fi Extender / Mesh
Weak signal is the #1 cause. A mesh system fixes dead zones.
