HI, I purchased a refurbished computer from Amazon. : Dell Vostro 3800 Desktop Computer, Intel Quad Core i7-4770 up to 3.9GHz, 16G DDR3, 512G SSD, DVDRW, WiFi, Bluetooth, HDMI, VGA, Keyboard, Mouse, Win10 Pro 64


After I connected the computer to our network, our internet became unstable: some time all computers loose internet connection, and come back later.

I think there might be ip conflict, or conflict from bluetooth. However I’m not too sure.

Please let me know how to know what cause the issue, and how to fix it



Thank you.
