OMEN - 15-ek0556nd
Microsoft Windows 10 (64-bit)

Hi I bought this notebok Omen 15 2020 ek0556nd for a few days and I am having a lot of problems, it started making blue screens and even sudden restarts while I am browsing or other, also I also take this opportunity to say that the wifi card seems to have problems because I have a very slow wifi connection with 5ghz, while with the old laptop I had never had similar problems.
Please someone expert tell me what I can do, I would like to understand if there is any hardware defect or just software and fix it, I bought this notebook on ebay, but I am covered by the warranty for 6 months or 1 year.

Close Command Prompt, reboot the system and then try to connect to the Internet.


Forget the wireless connection

If you’re having a “Windows 10 can’t connect to this network” error, you might want to “forget” your wireless connection in order to fix this problem. To forget the wireless network on Windows 10, do the following:

Open Settings App and go to Network & Internet.
Go to the Wi-Fi section and click Manage Wi-Fi settings.
Scroll down to the Manage known networks, select your Wireless network, and click Forget.
After you’ve done that, connect to the same wireless network again.

If the issue still persists after trying out the steps try running a system diagnostics on your PC and check if the hardware components on your PC are functioning correctly.
