Hello,
Hardware version is V1, writing it here since I couldnt select anything in the options.
So..
I did a cleanup of my setup, disconnected and then reconnected everything in the process ofc, but after some use I found out that something wrong was happening with my router c2 ac750: it disconnets regularly so i have to do a soft reset each time for it to work, my S7, when conneted to Wi-Fi, says it might be unavailable (it connects to Wi-Fi and everything but I cant use any apps that require internet data), the TV receiver (which is from my internet provider who provides television too) doesnt work since it requires internet but it for some reason doesnt connect. The only way I get to the internet is thorugh my pc. I did a hard reset but it doesnt seem to help in any way. I added a screenshot of the image which appears when I try to connect to the management menu.Is there anything I could do or should I just call my internet provider for help?

P.S. Im writing this post before going to sleep so I will be off for around 10 hours
