1. Avoid Direct Microcell Connection

Ensure your Microcell isn’t connected directly to the PC to ensure you don’t experience any power outage issues. There might be other technical issues with the AT&T Microcell setup, and combining it directly with the PC isn’t the best way to do this. In fact, a direct connection can heat the device, which worsens the power outage issue.

If you’re installing the device for the first time, you should plan your installation location. The best place is to install the AT&T microcell next to a window. Preferably, keep the device three feet away from the window since this helps to improve GPS signal reception. 

The device should also be a foot away from other wireless devices in the room to avoid potential interruptions. Plus, you should position the device near your internet equipment.

Give yourself about 10-15 minutes to set up, install, and activate the equipment. It may take another 90 minutes to start the AT&T microcell fully. You don’t have to do anything during the activation process since your vendor normally does it. 

Nonetheless, you’ll need your username, access ID, and password to activate the device online. You can do this online to proceed with the activation process.

Replace Outdated Equipment

2. Replace Outdated Equipment

Another quick fix to the AT&T microcell technical error is to replace your old, outdated equipment. Old equipment may not perform well since specific components aren’t updated to function optimally.

That said, AT&T shut down its 3G network. It’s the main reason why you may experience issues with your equipment. Your device may not work because it can no longer receive 3G signals. Luckily, there are other options to ensure you stay connected.

Introducing Wi-Fi Calling

With your AT&T Microcell 3G not working, AT&T recommends staying connected using Wi-Fi calling. Wi-Fi calling is easy to set up, and you can text and call in more places.

When coverage isn’t available on your phone, you can use Wi-Fi for calls and texts. Likewise, you can make calls and send text messages if your phone has an internet connection.

It’s worth noting that you can make calls to numbers within the U.S. for free. However, you will also be charged a standard rate for text messages.

Requirements to use Wi-Fi Calling

To take advantage of Wi-Fi calling, you need:

To be sure you’re using Wi-Fi calling, check the Wi-Fi icon on your smartphone, which you can find on your phone’s status bar. For Android smartphones, you should see a plus sign (+). In addition, apple smartphones will display AT&T Wi-Fi, and Android phones will also have a Wi-Fi icon when you want to make or end a call.

3. Check Your Connected Devices

While thinking about AT&T Microcell troubleshooting, it’s also crucial that you check the connected devices. The issue with your device not working can result from how device connections within the network.

Before you try anything to fix the problem, disconnect all the devices within the network. Wait for a few minutes and reconnect the devices. Disconnecting the devices and reconnecting them could help fix any network or signal reception issues.

4. Check Your Internet Speed

In some cases, your internet service provider’s speed may not match the AT&T Microcell, which affects the performance of your equipment. Confirm that the internet speed matches the internet speed you want to subscribe to. For slow connections, consider talking to your service provider to upgrade your speeds to what you had opted for.

Relocate Your Wi-Fi Router

5. Relocate Your Wi-Fi Router

Your Wi-Fi router’s location can prevent it from generating strong signals, meaning you’ll experience some technical issues. Position your Wi-Fi router next to the window where it can get fresh air and receive network signals. So, avoid putting the Microcell in a closet or the basement since such locations will prevent the device from receiving GPS signals after installing your equipment.

When placing the Microcell next to the window, ensure it’s also unobstructed. Remove other devices or objects that could prevent the device from getting signals as required. 

If there are other wireless broadcasting devices next to your equipment, keep them one foot away.

6. Check Your AC Adapter

Check your AC power adapter if the solutions above fail to work. Using a voltmeter, confirm that the readings are 16VDC +/- 0.5. The ATT Microcell may not work because a power outage overheated the Microcell or the adapter. You’ll have to find a replacement if the problem is with the Microcell. 

Keep in mind that AT&T discontinued MicroCell, meaning you’ll have to find alternatives. One of the main reasons for MicroCell’s discontinuation was the outdated 3G technology.

Why is AT&T MicroCell Not Supported or Working Anymore?

AT&T Microcell is no longer supported because AT&T shut down its 3G network to pave the way for 4G MicroCell and ultimately to MicroCell 5G. As a result, your AT&T Microcell may not work. Luckily, you can always turn to reliable alternatives like Wi-Fi calling.
