When using wireless LAN connection, video
from the Network Contents server* is not
played back or video frames are dropped
during playback.
hHigher transfer rate router such as 802.11n
(2.4 GHz or 5 GHz) or 802.11ac wireless
router may solve the problem. If you use
802.11n (2.4 GHz or 5 GHz) or 802.11ac
wireless router, it is necessary to set the
encryption type to “AES”.
Simultaneous use with a microwave, cordless
telephone etc. at 2.4 GHz may result in
connection interruptions or other problems.
hOn the “Wireless Settings” screen (>33), the
continuous lighting of at least 4 “Reception”
indicators is the target for a stable connection.
If 3 or fewer indicators are lit or the
connection is being interrupted, change the
position or angle of your wireless router and
see if the connection state improves. If there
is no improvement, connect to a wired
network and perform the “Easy Network
Setting” (>17) again.
