Meanwhile I bought an used internal wifi module on ebay and replacedcmy damaged one.
Worked perfectly fir a couple of hours and now it's not working anymore...
Any idea of what's happening?

Later on I switched to int-wifi and , you won't believe it, it started back to work.
Few days after it stopped working again and so I switched back to ext-wifi.
That happened a couple of months ago.
Today I tried back to switch to int-wifi and it's working again...
What is happening to my tv?
I'm very curious at this point...
