Hello,

I have not been able to connect my wireless tv to home network.

When I check the LAN wireless security on the config page it says it is disabled.

Have added the tv mac address to the wireless client filter (as that is what has to happen to to allow access to the wireless network for all other devices) and confirmed multiple times that mac address on filter and provided by tv are the same.

Have had to 60 inch version of bravia tv previously connected to wireless network without issue (although I did not set that one up, which may be the current issue) :D

Thanks in advance.
