Why does Wi-Fi appear duplicated after creating a new user in Windows 10?

Question

I asked this question and when I tried the solution, everything was fine, until I noticed that one of the bugs appeared again.

Basically, my Dell Inspiron 14R came from a repair with a new SSD with ,a fresh installation of Windwos 10 Home Single Language. It had one account, named 'user'. I tried to change it with Control Panel and then running Control UserPassword2. The profile changed (probably at the first try), but the user folder did not.

I noticed two bugs during this process and what I think is more relevant is that my home Wi-Fi network was duplicated, appearing as in this example: NETWORK and NETWORK 2. My Wi-Fi wasn't working since last year and now it came back, but with this problem.

I followed the solution, deleting 'user' and creating a new administrator using net. Then, I created a basic account for me. I deleted some shortcuts and uninstalled Node.js. I also associated this new account with a Microsoft one.

And then, I noticed my Wi-Fi duplicated again. I had associated and disassociated the previous 'user' account to my Microsoft account before all this story. I don't know whether there's some correlation. I think this is the only thing that is duplicated. I ran a full antivirus scan at different steps, no threats detected.

Both times, I solved the issue removing both networks. It's all OK for now. I tried restarting router to see if the bug shows up again, but it's all fine.

How to explain all this? Is this bug enough to worry about? Some time ago, Dell support told me that they aren't updating drivers for Windows 10 for my notebook.
