If you want to DIY repair of course you can. If you can't find the module, then no but why do this at all?
There are far better solutions with external Roku sticks along with those from Amazon that will give you better WiFi range and a smarter TV than what I've seen on Samsungs.
Also, you may be having OTHER THAN A WIFI MODULE issue. Samsungs are notorious for range issues. You must test this at 20 and less feet to the router.
I own an older Samsung Smart tv model # PN51E6500. I'm having internet connectivity issues, I was told I need to replace the Wi-Fi module and would cost me just over $300.00 (Canadian) to replace it. I watched a YouTube video on replacement and it looks fairly simple to do myself. Few questions, where can II buy the part? I've searched but can't find one. And is it just a matter of unplugging the old module and plugging iin the new one or is there more to it than that? The video made it look simple but the video was not for my specific model. Thanks
