Troubleshooting WiFi issues on the Yealink T46

If you're suffering with WiFi connectivity issues using your Yealink T46 handset, then you may wish to troubleshoot the issues yourself. We've provided a guide for the most common issues and their solutions below.

Phone will not connect to WiFi network

Check WiFi dongle

Sometimes the USB dongle can be dislodged during transit of the phone. Double check your Yealink's WiFi dongle in the rear USB slot on your Yealink phone. Remove it and re-insert it all the way to ensure that it is firmly in place.

Check WiFi is enabled

Navigate to menu>basic>Wi-Fi and check that the first option says "Wi-Fi: On". If not, use the right arrow key to enable WiFi.

Check network

You should try and connect to your network using a computer or mobile. It might be that your WiFi network is currently experiencing issues, and therefore no device will be able to connect correctly.

Password correct

Double and triple check that you have entered the correct password on the Yealink's setting screen. Often people mistype a password. You should also double check that you're inputting the correct password. The password will be the one you use to connect other devices (such as mobiles or computers) to the network.

Correct dongle?

Remove the dongle to ensure that it is the correct model. You're looking for a WF40 WiFi dongle. It has a USB connection and a small black curved end. It also has a WiFi icon etched into the outside. If you don't have the correct dongle, contact your communications provider.

Other phones connect

If you have multiple Yealink handsets available, try and connect other phones. If they connect then you may have a faulty handset or a WiFi dongle. Try switching the dongle with another (if you have one) and see if it connects to the network. If you have a phone from Bytes Digital, get in touch and we can ship you a replacement.

WiFi is connected but I cannot make calls

Configure your WiFi for SIP

You should check that your router is configured for SIP. This is a complex process and we would advise you talk to your communications provider about this before attempting to fix it yourself.

Check if your internet is down

Try browsing online using a computer or mobile. If your broadband connection is down, the Yealink will still be able to connect to your WiFi network, but it will not be able to make calls.

Test your internet speeds

Run an internet speed test using a computer or mobile. If you are suffering from low speeds, this could cause calls to drop out or not connect correctly.

WiFi keeps dropping in and out

Check WiFi dongle

Your Yealink's WF40 WiFi dongle may have come loose at the rear of your deskphone. Press on it firmly to ensure it's fully inserted into the phone.

Clean the USB port

Try cleaning the inside of the USB port. Use a cotton bud (or small cloth) to clean the port. Be careful not to be too rough, as you may damage the connections.

Check your network

Ensure that your network is fully operational. You can use a computer or a mobile to ensure that the connection is stable. Try streaming a video to look for dropouts.

Check your broadband line

It may be that a network provider such as Openreach are doing some work in the local area. This may create line and service affecting issues to your broadband lines. If this is a common occurrence, you should look at 4G WiFi as a backup to prevent frequent downtime.
