For those who get frequent WiFi connection drop-outs, I picked this bit of useful info from another forum. Note that this may well apply to many other LG models than the C9, as they often use common WiFi internal cards/modules: "Network/Ethernet/Wi-Fi Problem: C9 [or other models] will lose the wireless connection and you have to reconnect daily (but wired is stable); Conditions: TV is connected to a 5GHz router; Cause: (1) the router may be unstable on the 5GHz band [possibly too far from router]; (2) the router has the 5GHz band set on a higher channel - over 100; Resolution: (1) change the TV to the 2.4GHz band (2) set the channel [in the ROUTER advanced WiFi settings]!! for the 5GHz band below 100 (ex. 40-50) - [channel 36 is often OK]."
