AT&T Fixed Wireless Slow Wi-Fi - Solutions & Things to Know

Learn what you can do to improve your W-Fi and understand FWI

First, AT&T Fixed Wireless is not the same as AT&T Internet. Fixed Wireless internet uses the mobile signal to bring you internet. Home Internet uses either copper or fiber. Let's get into some fixes!

First, let's try some fast fixes to speed up your Wi-Fi.

If the above does not work, optimize your settings:

1. Sign in to Smart Home Manager
2. Once signed in, scroll to the "Let's Scan for Better Wi-Fi"
3. Select "Scan Now"

Smart Home Manager will find the best channel. If you want to manually sign in to the modem to test channels on your own, check the Update Wi-Fi Info section of the Change Wi-Fi Network Info.

Helpful Hint: Each home is different so you may need to test a few channels. 

What are normal speeds for fixed wireless

Because Fixed Wireless Internet uses the AT&T Mobility network to provide internet service, your speeds will vary depending on network congestion. The more devices connected to AT&T mobile network, the more strain it can put on our network. This means your internet speeds could stay consistent around 25Mbps or drop 10Mbps if there is a lot of congestion. This is normal.  

On top of that, the number of devices connected in your home can impact speeds. More below. 

How Many Devices are connected?

The number of devices can impact your experience. Let’s say you are getting 25Mbps and you are streaming on 4 devices and network congestion is not an issue, each device will use roughly 4-6Mbps per stream. Multiply that by 4, your devices can take up to 16 to 24Mbps. This means you have roughly 1 to 8Mbps of free resources. It all depends on what you are doing, how many devices are online, and congestion.  

There is currently no way to speed up service when congestion is an issue at this time. 

Minimize Interference

If electronics, like speakers or sound systems, are near the modem, the interference those devices emit can affect your speeds and slow you down. The links below go over how you can improve the modem environment and the best spot for the modem.

Heads Up: It is normal for wireless speeds to drop in half. Run a wired speed test with only 1 device connected. Learn why now.
