I bought a Windows 10 home edition laptop from my school, and when I reached home I noticed my Primary DNS Suffix was "DELIA.DGOS". Even when I'm at home. Image

So, I tried changing it via the Control Panel, but after a restart, it says the same. I even tried changing the registry key value of: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DNSRegisteredAdapters\WifiCardID\PrimaryDomainName

But after a restart, it changes back. I don't want my laptop name to end with this DNS suffix. How do I change it? Is it hard-coded into the wifi card?

I ran several commands to determine it:

There are several possibilities.

1. Do a TCP / IP Reset: Open cmd.exe with Run as Administrator Then: netsh int ip reset c:\resetlog.txt Then: ipconfig /flushdns Then: restart the computer and test the DNS

2. Try re-installing the wireless card.

Then, 3. If these regular solutions do not work, then try a USB Wireless card as that should work
