What This Error Means
F28 on an Amazon Echo Dot means setup or update failed because the Dot can’t complete its connection to Amazon’s servers.
Translation: the Dot is talking to your Wi‑Fi, but the handshake to Amazon (account or internet side) is breaking, so it bails out and throws F28.
- Shows up most often during first-time setup or after a firmware update.
- Light ring usually goes orange, maybe purple, then setup fails in the Alexa app with F28.
- Root causes: weak Wi‑Fi, wrong password, router security settings, blocked ports, or a glitched registration on your Amazon account.
Official Fix
Do it the way Amazon expects first. Follow this order so you don’t chase your tail.
- 1. Power-cycle the Dot
- Unplug the Echo Dot from power.
- Wait 30 seconds.
- Plug it back in and let it fully boot (light ring settles) before retrying setup.
- 2. Confirm your Wi‑Fi actually works
- On your phone, connect to the exact same Wi‑Fi network you’re trying to use for the Dot.
- Open a browser and load a couple of sites. If that’s flaky, fix the internet first. F28 will never clear on bad internet.
- 3. Use a simple 2.4 GHz network
- Echo Dots are happiest on 2.4 GHz with normal WPA2 security.
- If your router has 2.4 GHz and 5 GHz with the same name, temporarily give 2.4 GHz its own SSID (like
MyWiFi_24). - Avoid guest networks that need a browser login, hotel Wi‑Fi, or enterprise networks.
- 4. Re‑run setup cleanly from the Alexa app
- Open the Alexa app.
- Go to Devices > “+” (Add Device) > Amazon Echo > Echo, Echo Dot, Echo Pop.
- Put Dot in setup mode if needed (orange ring): usually hold the Action button until the ring turns orange.
- Select your Dot, choose the correct Wi‑Fi, and type the password slowly. One wrong character = F28.
- 5. Check Amazon account and region
- In the Alexa app, make sure you’re logged into the same Amazon account you used to buy / register the Dot.
- If the Dot was someone else’s, have them deregister it from their Amazon account first.
- 6. Turn off router weirdness (temp)
- On your router, temporarily disable: MAC filtering, parental controls, and any “block new devices” feature.
- Make sure Wi‑Fi security is set to WPA2-Personal (AES), not WPA3-only or mixed TKIP junk.
- Reboot the router after changes, wait 2–3 minutes, then try setup again.
- 7. Factory reset the Echo Dot (last official step before calling support)
- Echo Dot 3rd/4th Gen: Hold the Action button for ~25 seconds until the ring goes off and back on.
- Echo Dot 2nd Gen: Hold Mic Off + Volume Down for ~20 seconds.
- Wait for orange ring (setup mode), then re‑add it in the Alexa app as a new device.
- 8. If F28 still shows up
- At this point, Amazon’s official line is: contact Customer Support and they’ll walk the same tree again and maybe offer a replacement if it’s clearly a hardware issue.
The Technician’s Trick
When the official dance doesn’t kill F28, this is what actually works in the field.
- 1. Bypass your router with a phone hotspot
- On your phone, turn on a personal hotspot. Keep the name and password simple (no emojis, odd symbols).
- In the Alexa app, run setup again and connect the Dot to that hotspot.
- If it sets up fine and stops throwing F28, your Dot is fine and your router is the problem (security mode, firmware, or blocking Amazon).
- Now you know where to focus: router settings or new router.
- 2. Hard-deregister, then re‑add
- On a computer, go to Amazon > Content & Devices > Devices.
- Find your Echo Dot, click it, and hit Deregister.
- Unplug the Dot for 30 seconds, plug back in, wait for orange ring, then add it as a brand new device in the Alexa app.
- This clears weird half-registered states that often trigger F28.
- 3. Lock router Wi‑Fi to basic settings
- On the router’s Wi‑Fi settings, set:
- Mode: 802.11b/g/n (no “ax only” / Wi‑Fi 6 only).
- Security: WPA2-Personal (AES only).
- Channel width: 20 MHz on 2.4 GHz.
- Save, reboot router, then redo Echo setup. This removes 90% of compatibility weirdness that causes F28.
Is It Worth Fixing? (The Financial Verdict)
- ✅ Fix: Echo Dot is under 5–6 years old, powers on fine, and F28 only shows during Wi‑Fi setup — fix it; this is almost always network or account, not a dead speaker.
- ⚠️ Debatable: Dot is older, Wi‑Fi is known flaky, and you were already planning a router upgrade — maybe bundle the fix with a new router or mesh system instead of fighting F28 all weekend.
- ❌ Replace: Dot won’t hold power, constantly reboots, or fails even on a clean phone hotspot and different account — the radio or board is likely toast; replacement Echo is cheaper than hours of troubleshooting.
