i have one white box version unifi tv box, previously connected to LAN port 4 (normally for iptv port) without any problem. But now the LAN cable is broken above the ceiling, maybe get bitten by rats, so i connect using the wifi 2.4g but cannot view any content, the screen is black, i reconnect using lan cable again it work fine.

any sifu here know whats the cause? or memang cannot stream using wifi?
