You open the Alexa app, scroll to your Echo Show 15, and that gray "Offline" tag is back again. The screen is dark, the speaker is silent, and voice commands do nothing. Sometimes it stays connected for hours, sometimes it drops out within minutes, and nothing obvious triggered it.
Start with the quickest fix: unplug the power adapter from the back of the Echo Show 15, wait 30 seconds, and plug it back in. The screen will light up, show the blue Amazon logo, and rejoin your network within two minutes. If it shows online again, you're done. If not, work through the rest of this guide.
What Usually Causes the Echo Show 15 to Show Offline
The 2nd-gen Echo Show 15 (2024) runs on a newer processor and supports Wi‑Fi 6E across 2.4, 5, and 6 GHz bands. That tri‑band radio is a big upgrade over the original model, but it also introduces a few failure points. Here are the most common culprits:
- Router rebooted overnight: your ISP pushed a firmware update, the router restarted, and the Echo Show didn't reconnect cleanly.
- DHCP lease expired: the IP address the Show was using got reassigned to another device, and it never requested a new one.
- Wi‑Fi 6E band‑steering confusion: the Show tries to hop from 5 GHz to 6 GHz but ends up in a weak zone where neither band is stable.
- Family Hub widget desync: after a firmware update, one or more widgets can hang, causing the entire device to appear offline to the Alexa cloud.
- Fire TV menu background process stuck: the built‑in Fire TV interface sometimes leaves a process running that interferes with the Wi‑Fi daemon.
Is Your Network Actually Working?
Before you dig into the Show itself, check if other devices are online. Open a webpage on your phone while it's connected to Wi‑Fi (not cellular). If your phone is also struggling, the problem is your router or modem, not the Echo. Reboot the router, wait a minute for it to come back up, and the Show will likely reconnect automatically.
If your phone is fine but the Show is the only offline device, move on to the fixes below.
Do a Clean Power Cycle
Pull the power cable from the Echo Show 15 (unplug from the device itself, not the wall brick). Wait at least 30 seconds, long enough for the internal capacitors to drain. Plug it back in and watch the screen. You should see the blue Amazon logo, then a brief setup animation, then the home screen with widgets. Open the Alexa app and the device should appear online within 60 seconds.
If you're wall‑mounted and the power cable is hard to reach, flip the circuit breaker for that room for five seconds, then turn it back on. Same result.
Reconnect to Wi‑Fi Using the Alexa App
Open the Alexa app, tap Devices at the bottom, then tap your Echo Show 15. Scroll to Wireless and tap Change. The app will walk you through selecting your network and entering the password. If you recently changed your Wi‑Fi password, this is almost certainly your problem, the Show won't show a "wrong password" error, it'll just go offline.
If your router splits the 2.4, 5, and 6 GHz bands into separate SSIDs, pick the 5 GHz network. A single combined SSID with aggressive band steering often causes the 6 GHz handshake to drop on the Echo Show 15. The Show works fine on 6 GHz once connected, but the initial handshake is where most issues happen.
Renew the DHCP Lease
If the Show reconnects but goes offline again within a few minutes, your router may be issuing it a conflicting or expired IP address. Log into your router's admin page, find the DHCP client list, and remove the entry for your Echo Show 15. Then power cycle the Show, it will request a fresh lease and usually stay online afterward.
On most routers this setting lives under Network > LAN > DHCP Server. If that sounds unfamiliar, rebooting the router accomplishes the same thing 90% of the time.
Check Amazon Service Status
If multiple Echo devices in your home show offline at the same time and your home Wi‑Fi is working fine, the problem may be on Amazon's side. Head to status.aws.amazon.com or search "Alexa down" on social media. Amazon's voice services have had short cloud incidents that take Echo devices offline even when the radio is healthy. If there's an active outage, no device‑side fix will help, wait it out.
Force a Firmware Update Check
Amazon pushes Echo firmware updates silently, usually overnight. To force a check, leave the Echo Show 15 plugged in and idle (screen on, no video playing) for 30 minutes. The device pings Amazon's update servers when it's not being used and downloads any pending firmware. After 30 minutes, power cycle the Show, the new firmware installs during the next boot.
If you notice Family Hub widgets desyncing after a recent update, this is a known intermittent issue on the 2nd‑gen model. A quick power cycle usually resolves it until the next update.
Deregister and Re‑register the Device
When the Show is connected to Wi‑Fi (you can see its IP in your router's client list) but the Alexa cloud insists it's offline, the device‑to‑account binding has broken. Open the Alexa app, tap Devices > Echo Show 15 > Deregister. Then run setup again from scratch by tapping Devices > + > Add Device.
Deregistering removes all Skills and routines tied to that device, but your Amazon account and Alexa+ subscription (if you have it) remain intact. You'll need to re‑enable any custom widgets and Fire TV apps after setup.
Factory Reset as a Last Step
If nothing else has worked, a factory reset will clear any corrupted settings or stuck processes. On the Echo Show 15 (2nd Gen), go to Settings > Device Options > Reset to Factory Defaults. Confirm the reset on the touchscreen. The Show will reboot, wipe everything, and walk you through initial setup in the Alexa app.
Resetting erases Skills, routines, and any paired smart home devices. It also wipes your Fire TV login, so you'll need to sign back into your Amazon account for Fire TV mode. If the reset fails to complete after two tries, the screen freezes or the device never finishes booting, that points to a hardware issue, and you'll want to contact Amazon support.
