Devices connected to my HUAWEI CPE/HUAWEI Mobile WiFi have slow Internet connections

Problem:

Devices connected to the HUAWEI CPE/HUAWEI Mobile WiFi with a SIM card inserted have slow Internet connection.

Solution:

1. Move to a location with better network signals.

Place the HUAWEI CPE/HUAWEI Mobile WiFi in an environment with strong and stable network signals. You can determine the network signal strength based on the indicator displayed: more bars indicate a stronger signal.

2. Check whether a connected device is downloading data.

If a device connected to the HUAWEI CPE/HUAWEI Mobile WiFi is downloading a large amount of data, the quality of Internet connection for other connected devices will be affected. Wait until the download is complete.

3. Avoid using the device on fast-moving vehicles.

When the HUAWEI CPE/HUAWEI Mobile WiFi is used on a fast-moving vehicle, such as a high-speed railway or train, the Internet connection speed will be affected.

4. Check whether your traffic is rate limited.

Your Internet connection when using HUAWEI CPE/HUAWEI Mobile WiFi will be poor when your traffic is rate limited. Avoid downloading a large amount of data when your traffic is rate limited.

5. Use the device in a place with good heat dissipation.

HUAWEI CPE/HUAWEI Mobile WiFi has a temperature protection mechanism. When the temperature is too high, the Internet connection speed will be lower. Use HUAWEI CPE/HUAWEI Mobile WiFi in a place with good heat dissipation.

6. Keep the device away from interference.

When there are obstacles (such as cement walls) that weaken the Wi-Fi connection, or household appliances (such as microwave ovens and TVs) that cause interference, the connected devices will have slow Internet connection. Move your device closer to the HUAWEI CPE/HUAWEI Mobile WiFi, and try keeping both away from any obstacles or other home appliances to reduce interference.

7. Replace the SIM card and try again.

Use another SIM card and check whether the connection is still slow.

• If the issue persists, check what kind of SIM card is being used, and contact the carrier.
• If the issue persists, take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
