I have a 1st gen Shield TV but the WiFI is toast (and along with it connectivity to the remote and the controller (unless I use a usb cable to connect the controller)
I had a case with Nvidia but it got no where and the issue got worse.
I had used it wired for most of the time I had used it when the issue first started.
So I was wondering how hard would it be to replace the wifi chip? And would a good repair shop be able to to it? (Maybe one of those places that fixes phones.)
