A year ago I bought this TV and it worked for a week or two and then stopped connecting to the servers. I tried changing the settings to 8.8 8.8 with no luck. Today I managed to get it to work and then out of the blue my TV stopped connecting to my router. I cannot connect wirelessly to my router. I've checked and I'm 100% sure the password is correct I've turned off the router and turned it back on and I'm using it with several other devices to no avail. What can I do
