WiFi chip replacement on Shield TV

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.)
