Hello,

It's been week I'm trying to make this work again .. because like 6 months to 1 year ago I managed to make it work, don't know what changed since.

So, I have a 2018 UHD Samsung TV (Model UE49NU5105 or UE49NU7105 sth like that).

I have a built pc with a Asus PCE-AC55BT as Wifi + Bluetooth card that I changed lately thinking it could solve that problem (previously I was using wifi with a wifi USB dongle to access the tv but it stopped working at some point)

My problem is that my pc can't detect the TV, when doing Windows + K or being in the device page.

While other laptops in the house manage to see the tv and connect to it.

And everything mentioned is on the same Wi-fi.

I searched a lot online and tried a lot of things but I'm starting to feel defeated.

I checked the advanced parameters of my wi fi yesterday and saw that my pc is mostly using a 5 MHz bandwidth wifi thingy while most other things a 2.4 MHz one, tried to force the PC on the 2.4 MHz to see if it changed anything with no results.

I also tried to change the wifi password encoding since windows said it was outdated, and saw that at that time, before I could change the wifi password on one of the laptop, it could still connect to the tv without being connected to any internet and successfully managed to mirror itself on the TV, so I thought that it could maybe connect itself to the TV by bluetooth .. is that possible ?

+ I tried every other common troubleshooting advices I could find.

Honestly I don't really know what more to do, does someone have an idea ? Or is there maybe a better way to wirelessly connect my PC to my TV (In order to stream sports and films from my PC on the TV mainly)

Thank you.
