Networking (LAN/Wireless LAN)
What are channels?
❑ Wireless LAN communication uses divided frequency bands known as channels. Third-party wireless LAN access point
channels may be preset to different channels from Sony devices.
❑ If you are using a wireless LAN access point, see connectivity information contained in the manual that came with your
access point.
Why does the network connection stop when I change the encryption key?
Two computers with the wireless LAN function may lose a peer-to-peer network connection if the encryption key is changed.
You can either change the encryption key back to the original profile or re-enter the key on both computers so the key
matches.
