Our wifi keeps dropping out

Nice to meet you, *****!

Have you ever experienced this issue before?

Ok, is it dropping down on all your devices or only the TV?

How many devices connect to it right now?

Your internet may keep cutting out because you or your internet provider must resolve one or more issues. However, your modem also may be faulty, or you may have too many devices using too much data simultaneously.
What is your router model?

Huawei, correct?

Then, let's try to do a factory reset first to see if the problem occurs after that.
However, I must warn you: A factory reset restores the modem to the default settings – all remembered Wi-Fi connections and any user customizations, such as your Wi-Fi name and password, are erased.
Are you ok with that?

You'll need to set it up as a new device.
What is your internet provider?

Then it'll be more automatic.

However, before we start, please check the back of your modem. There should be a sticker with your default Wi-Fi network and password details.
Can you see it?

Great! To factory reset your modem, do the following:

1. While the modem is turned on, insert a paper clip into the reset hole on the side, press down for 8 to 10 seconds until all the modem lights turn off, then release.
2. The modem will reset and then restart. This process can take up to 5 mins for the connection to establish.
3. After a factory reset, you must manually reconnect each WiFi device using the default password on the back of your modem to connect to the Network.

When you're done. Power and WAN light should be GREEN and steady. Internet light and a LAN light should be GREEN and blinking. The WLAN light should be GREEN and blinking.
