Getting your Ring Sensor offline doesn’t only cause inconvenience but also makes your home security system vulnerable. So, in this post, I will talk about why this may be happening and what you can do about it.
Why Your Ring Sensor Keeps Going Offline?
From what I’ve noticed, your Ring Sensor might often go offline primarily due to two main issues: weak Wi-Fi signals and low battery power. The Wi-Fi problem might stem from the sensor being too far from your router or thick walls interfering with the signal.

On the battery front, if the power is too low, the sensor struggles to maintain a connection. I’ll dive into the solutions for these issues in detail in the next section.
How Do I Get My Ring Sensor Back Online?
Now that you know the common issues that can make your Ring alarm sensor offline, here are a few fixes:
1. Change the Battery
Ring sensors are powered by batteries that can last “up to” three years, but their lifespan may vary based on usage and environmental factors. A low or drained battery may not have enough power to transmit signals to the Ring Base Station or communicate with other components of the Ring Alarm system.
For 1st Gen Ring Alarm Contact Sensors, use one CR123A battery. The battery can last up to three years. To replace it, press the cover release, remove the cover, replace the battery ensuRing correct polarity, and then reattach the cover.
For 2nd Gen Contact Sensors, if you face difficulty removing the battery, use a small tool like a screwdriver to push the battery out gently from the slot. Ensure correct battery polarity when inserting new batteries.

2. Use Alarm Range Extenders
Ring sensors connect to the Ring Alarm Base Station using Z-Wave technology, a type of radio wave that enables smart devices to communicate with each other. This technology has a limited range, and if your sensors are out of range, they won’t be able to communicate with the base station.
The Ring Alarm Base Station has a Z-Wave range of 250 feet, but physical barriers like walls and other large objects can weaken or disrupt the Z-Wave signal, thus reducing this range.
The Ring Alarm Range Extender helps eliminate dead zones, ensuring your Ring Alarm devices stay connected. It’s particularly useful for larger homes. Install this extender in an outlet between your Base Station and the farthest security device from your Base Station to strengthen the Z-Wave network signal.
For best performance, keep it plugged in at all times. It also includes a 24-hour backup battery in case of power outages. If your Range Extender has trouble connecting, try a different outlet, ensure it’s receiving power, or press the button on the device for troubleshooting steps.
3. Counter Z-Wave Interference
Z-wave interference is a less common problem, but it can occur if physical barriers in your home block the signal. Various electronic devices and materials in your home may also disrupt the network. It may also happen if you have many Ring sensors.
Here’s what you can do to prevent Z-Waze interference:
- Move your Base Station to a more centralized location.
- Relocate other electronic devices that may interfere with the signal.
- Use additional Range Extenders if needed.
- Be aware of materials in your home that might block the signal, like thick walls or metal objects, and plan your device placements accordingly.
If you are still experiencing Z-Wave interference, try turning off or replacing other 900 MHz devices in your home, like cordless phones or baby monitors. Additionally, rebuilding the Z-Wave mesh network from the hub outwards, adding one device at a time, can help establish stronger connections.
4. Reconfigure or Reset

Just like any other technology, Ring sensors and the Ring app can experience glitches and bugs.
For Ring Alarm Z-Wave devices like Contact Sensors and Motion Detectors, you could reconfigure your device through the Ring app:
- Tap the menu (☰) > Devices.
- Select your device.
- Tap Motion Settings > Advanced Settings > Z-Wave > Remove Z-Wave Device > Remove.
- It will give the message “Remove device, listening for device to remove.”
- Now, press and release the pinhole reset button. This will remove the device successfully and now you can re-add it using the Ring app.
If the Contact Sensor is still waiting or attempting to connect to the Ring app, factory reset it. This will remove the device from your Alarm Base Station and reset it to its default settings– potentially clearing up any glitches that may be making it go offline. Here’s how to reset your Ring sensor:
- Take the Contact Sensor off its base while making sure it still has the batteries.
- Press the pinhole reset button and hold it until the LED light turns red, then release it.
- The factory reset is done. Now, re-add the Contact Sensor to your Ring Alarm to see if it is working fine.
5. Replace The Ring Sensor

Sometimes, the problem may be due to a hardware issue within the device. If you’ve tried all other fixes and your sensor is still offline, the issue might be with the hardware. In this case, it’s best to contact Ring support for assistance or consider exchanging the device if it’s still under warranty.
Why Does My Ring Base Station Keep Going Offline And How To Fix It?
When your Ring Base Station goes offline, it might be due to several reasons. Here’s how you can identify and fix these issues:
⚡ Power Supply Issue:
Sometimes, the Base Station might go offline because it’s not getting power. Make sure it’s plugged into a working outlet. The Base Station has a backup battery, but if the battery is not charged or faulty, it won’t help. Check if the Base Station is on, and if it still shows offline, look into other possible issues.
🌐 Ethernet Cable Problem:
If your Base Station uses an Ethernet cable for the internet, a loose connection might be the culprit. Ensure the Ethernet cable is properly inserted. A firm connection is crucial for keeping the Base Station online.
📶 Wi-Fi Band Conflicts:
The Base Station can work with both 2.4GHz and 5GHz Wi-Fi bands. If it keeps going offline, the current Wi-Fi band might not be functioning well. Here is how to change the band:
- Log into your router’s admin page using a web browser.
- Enter the router’s username and password.
- Navigate to the Wi-Fi settings section.
- Find the option to select Wi-Fi bands (2.4GHz or 5GHz).
- Choose the band you want to switch to.
- Save the changes.
- Restart your router for the changes to take effect.
📡 Router Distance Issues:
A weak Wi-Fi signal can cause your Base Station to disconnect. This might happen if the router is too far away. Moving the router closer or using a Wi-Fi extender can strengthen the signal and keep the Base Station connected.
🔄 Router Glitches:
Routers can sometimes have internal errors that lead to connectivity problems. To restart your router and fix this issue, follow these simple steps:
- Unplug your router from the power outlet.
- Wait for 30 seconds.
- Plug the router back into the power outlet.
- If your router has a power button, press it to turn off the router, wait a few seconds, then press it again to turn the router back on.

🔁 Base Station Needs a Reboot:
If the Base Station is offline, rebooting it might help. To do it, follow these simple steps:
- Unplug the Base Station from the power outlet.
- Remove the Ethernet cable from the Base Station.
- Open the Base Station’s cover to access the backup battery.
- Take out the backup battery and wait for 30 seconds.
- Reinsert the backup battery into the Base Station.
- Replace the cover on the Base Station.
- Plug the Ethernet cable back into the Base Station.
- Plug the Base Station back into the power outlet.
📱 Outdated Ring App:
An old version of the Ring app might cause issues. If your Base Station appears offline, check for updates to the Ring app in the Google Play Store or App Store and install them. Keeping the app updated can prevent connectivity problems.
🛠️ Firmware Out-of-Date:
Ring updates firmware to enhance device performance. An outdated firmware on your Base Station might lead to it going offline. Look for firmware updates in the Ring app and update your Base Station to ensure it operates smoothly.
