Alexa Won't Connect to Wi-Fi? 6 Fixes That Work

Updated November 2, 2026 · 6 min read

When Alexa won't connect to Wi-Fi, the Echo is usually stuck between an old saved network and a new one, or it's trying to join a band it can't use. These six fixes are ordered by likelihood — most Echo devices are talking again by fix #3.

Fix 1: Put the Echo in setup mode

1. Press and hold the Action button (the dot) on the Echo for about 15–20 seconds until the light ring turns orange and spins.
2. Alexa will say "Now in setup mode."
3. On Echo Show models: swipe down from the top, tap Settings → Device Options → Reset to Factory Defaults is overkill for this — instead use Settings → Network to change Wi-Fi directly. But for screenless Echos, the Action button is the way.

Setup mode wipes the saved Wi-Fi credentials so the Echo stops clinging to a dead network. This alone fixes the majority of cases.

Fix 2: Re-run Wi-Fi setup in the Alexa app

1. Open the Alexa app on your phone.
2. Tap Devices → Echo & Alexa → select your Echo.
3. Tap the gear icon (settings) → Wi-Fi Network → Change.
4. Follow the prompts: pick your network, enter the password carefully, and wait for the Echo to confirm.

Make sure your phone is on the same Wi-Fi network during setup — the app hands the credentials over a local connection, and mismatched networks are a classic silent failure.

Fix 3: Check the 2.4GHz vs 5GHz situation

Older Echo devices (1st and 2nd generation, and some Echo Dots) are 2.4GHz-only. If your router merged both bands under one name, or the Echo is trying to join a 5GHz-only network, it will fail silently.

1. In your router's admin page, confirm the 2.4GHz radio is enabled (and give it a distinct name if your router merges bands).
2. Connect your phone to that 2.4GHz network.
3. Repeat Fix 2, selecting the 2.4GHz network name for the Echo.

If your Wi-Fi itself is dropping on other devices too, the problem may be the network rather than the Echo — see our Wi-Fi dropping guide or slow Wi-Fi fixes.

Fix 4: Restart the Echo and the router — in order

1. Unplug the router, wait 2 full minutes, plug it back in, and wait for solid lights.
2. Unplug the Echo for 30 seconds, then plug it back in.
3. Give the Echo a minute to boot and reconnect on its own.

Echo devices cache network state aggressively. A clean power cycle on both ends clears stale DHCP leases that a soft reboot sometimes doesn't.

Fix 5: Forget the network in the app and add it fresh

1. In the Alexa app: Devices → Echo & Alexa → your Echo → Settings → Wi-Fi Network.
2. If there's a "Forget" option for saved networks (under More → Settings → Network in older app versions), remove your network.
3. Put the Echo back in setup mode (Fix 1) and run through setup again from scratch.

Corrupted saved credentials are invisible — the Echo thinks it has the right password and never asks again. Forgetting forces a clean entry.

Fix 6: Check for updates, then deregister as a last resort

1. In the Alexa app, check the App Store / Play Store for an Alexa app update — an outdated app can fail setup on newer firmware.
2. Ask the Echo "Alexa, check for software updates" if it's partially connected, or leave it plugged in overnight — Echos update automatically when idle.
3. Last resort: in the app, go to Devices → Echo & Alexa → your Echo → Settings (gear) → Deregister. This removes the device from your Amazon account.
4. Set it up as a brand-new device afterward.

Deregistering erases the device from your account, so you'll need to re-add it and re-link smart-home devices. That's why it's last — but it clears account-side corruption that nothing else touches.

Frequently asked questions

Why does Alexa keep saying "I'm having trouble connecting"?

That phrase usually means the Echo has a Wi-Fi link but no working internet path — often a stale IP after a router change, or the router's firewall blocking Amazon's servers. Fix 4 (the ordered restart) resolves most of these. If it persists, check whether other devices can reach the internet on the same network.

Can an Echo connect to 5GHz Wi-Fi?

Newer Echo models (3rd gen and later, most Echo Shows) support both bands. 1st/2nd-gen Echos and early Dots are 2.4GHz-only. Check your model's specs — and when in doubt, use the 2.4GHz network; it's more reliable for smart-home devices anyway.

Will I lose my routines and smart-home devices if I deregister?

Routines live in your Amazon account, so they survive. But you'll need to re-link the Echo itself and re-discover smart-home devices afterward ("Alexa, discover my devices"). Back up any device groups you care about by noting their names first.

Alexa connects but keeps dropping off Wi-Fi. Now what?

Recurring dropouts are a signal or router problem, not an Echo problem. Check how far the Echo is from the router, look for interference from microwaves or baby monitors (both hit 2.4GHz hard), and consider a mesh node or extender near the Echo's room.
