Internet isn't limited, but it's not working.

One day I was just deleting unused files. I dont know if I deleted something importan.The next day internet were limited. I can provide this info:
-it says 'limited' under connected wi fi.
-troubleshoot problems results (There might be a problem with the driver for the wi fi adapter (ethernet adapter too)) It can't fix it automaticaly.
-when I enter ipconfig in cmd it just says Win IP config and that is it, no information at all...
-cant connect to my router by typing default gateway in browser.

Given only this detail

I'd get ready for an OS install. I can only guess this is a Windows OS but can't tell which. Most had a System Restore to go back to where it worked.

Next time you know to not delete those files.

It is Windows 10. So you say it's imposible to fix?

In your case, maybe.

Roll back

Can I roll back if I haven't set any backup drivers?

What are backup drivers?

I wonder if you meant "Can I roll back if I have no backups?"

Because we are never sure of the results on System Restore and more, the moderator line here is "We only lose what we don't backup."

I've used System Restore since 2000 (XP days) and never have encountered "backup drivers." Drivers for Windows are usually for hardware. Tell more.

Maybe this help???

I found setting called 'Reset this PC' If pc isn't running well I can reset, also keep or delete files and then reinstalls windows. This could help???

I use system restore first.

But as you suspect, backup of our stuff is a priority since we can't be sure if Microsoft's "keep files" will actually work. But hey, there are folk that will risk it all. I don't.

If you do a reset, you install the drivers needed if they are needed. Unlike Apple and their gear, PCs are different with very few alike. I can't guess what will and will not work after the reset.

PC reset worked out!!

It fixed all the issues. Some programs and apps werevunintaled but I can instal them again anytime. Before reseting I wanted to clear recycle bin. There I found folder named '$RPHS9A8' it was admin protected.

Alright, thanks for help folks,

Lenovo best.

PS. I take it's only this PC on this WiFi.

You're posting but what if the WiFi system (hot spot) is out and you are posting from a wired connection. It could be something else. Details matter and while I respect that folk want privacy when troubleshooting, the more detail the better.

Alright, the issue is only in that windows 10 lenovo laptop. 2 phones, tv and pc are connected throught wi fi and cable. They are all working good.
