Computer keeps dropping Internet connection

I bought a used computer and since I have attached it to my network I have had nothing but problems. First it seems as thought it was acting as a DHCP server somehow as some devices when connecting to my network would pick up the IP address of this new computer as the default gateway. I went into device manager deleted the network adapter and let it reinstall (not sure if that is correct)

Now it is constantly losing Internet connection and getting it back. It is hard wired, running Windows 10.

Here is what ipconfig says:




Not sure what to do next, but it cuts in and out every 2 minutes or so now.

If I understood this right... You didn't perform fresh Windows install?

When getting used computer, the first thing should be to wipe the drive clean and perform clean install of Windows.

If you really don't want to clean install (booting with Windows obtained from Microsoft... , while installing, delete all partitions and create new one), then at least reset Windows. Here are tutorial made by Brink: reset-windows-10

I bought this computer from a friend with a bunch of settings and setup exactly how I want, but if there is no where to look for a setting that can be causing this than I will tackle this project.

If this computer is part of some special project, then telling us what it is would greatly help

Follow Samuria's advice and it will show most of it

OK, I will get that all done.

I use the computer to do crypto-currency mining. In this case Burstcoin which mines off storage space. Shouldn't have an impact on the network settings.

It is just about halfway through plotting more hard drive space so I won't be able to restart for 9 hours. I will post all the logs after that.

Thanks!

Here are the logs:

FRST.txt Addition.txt

if it was acting as DHCP server something is running on the system removing the adapter won't stop it let's see what's going on



Please download and save FRST 64bit or FRST 32 bit to your Desktop.


http://download.bleepingcomputer.com/farbar/FRST.exe

http://download.bleepingcomputer.com/farbar/FRST64.exe

Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
Make sure that Addition option is checked.
Press Scan button.
It will produce a log called FRST.txt in the same directory the tool is run from.
Please copy and paste log back .
The first time the tool is run it generates another log (Addition.txt - also located in the same directory as FRST.exe/FRST64.exe).

Bumping now that I have posted the required docs

Sorry about that @superwindow. Setting up mining computer scared me off Don't have any kind of experience what have to run and what not.

That ccboot.exe from (Youngzsoft) is kind of proxy software, and if not properly configured could cause some mess. But have no idea, if you have to run it or not...

otherwise, I would disable WiFi adapter and IPv6

Good luck

Nope, I don't need to run it at all. I will uninstall and disable the items suggested.
