FAQs & Troubleshooting
The wireless connection is unstable. What can I do?
Please check the following:
Unplug and re-insert the power cable of your Access Point.
Check your Access Point manufacturers web site to see if there is any later Access Point firmware available.
Try using a different SSID name for the Access Point and the machine.
Make sure that no other wireless devices are interfering with your network. If so, temporarily switch those wireless devices off to see if the problem continues.
Bring your Brother machine closer to the Access Point.
