Check the following:
• Make sure your router or access point is turned on, and
is correctly connected to your computer or network
device.
• Turn off the router or access point, wait about 10
seconds, and turn it on again.
• Move your product closer to your router or access point,
and remove any obstacles between them. Also move
your product away from devices such as wireless
phones or microwaves.
• Confirm that the SSID shown on the network
connection report matches the label on your router or
access point. Also make sure your SSID uses only
ASCII characters and symbols, or your product cannot
display the SSID correctly.
• If you are trying to connect using the WPS push button
method, make sure your router or access point supports
it.
• If you are using a network password, check the label on
your router or access point to confirm that you are using
the correct password, or check with your network
administrator or router/access point documentation.
• If you are connecting to a smart device that generates
an SSID, check the device documentation for the SSID
and password you should use.
• If your wireless connection suddenly disconnects, and
another smart device was added to the network using a
WPS push button method or your network was set up
using a non-WPS push button method, try downloading
and installing your product software again.
