Use WEP. Input a key into key 1. These players have a problem with WPA. Also, set router channel 11 and not auto. And disable your firewall before making those router changes. Once changes are made, enable firewall again. Go connect your BD player. You can also try to turn off your security and get the BD connected first then go back and enable your security again.
I have a BD-C5500 that will not connect to my D-Link wireless router. I have done everything to get it to connect except remove the WPA and security key. It will not connect, but will connect without any problems with a network cable. I would not like to have 65'(20m) of cable running through my house.
Any suggestions would be much appreciated. I am running the lastest firmware 1018.
