I'm having a problem with a computer of an acquaintance of mine.
I'm normally the go to guy for people in my surrounding when it comes to problems but with this one I'm at a loss.
Maybe I'm overlooking a simple solution or maybe someone of you has the holy grail to fix this.
First some specs:
Dell XPS 720 with a broadcom NetXtreme 57xx Gigabit Controller
Windows 10 pro 64bit version 1703
intel core2quad 2.4Ghz
It started 3-4 weeks ago.
Troubles with internet, bad connection. Went on for a couple of days, owner contacted ISP, they replaced some cables and the modem and everything was fine again, for 2 weeks.
After 2 weeks no connection could be made again. Internet connection shows it's connected to an unknown network with no connection.
This is where I come in.
Not an unusual problem, seen it before and normally not a problem to fix. Most of the times even a simple full reboot helps.
This time, it is not. I tried a couple of things at the owners home, and then took it to my home to try to see if there is still something wrong in his network (Although other devices are working properly)
The things I tried (In no particular order)
Driver update/deleting driver and reinstalling
Removing the security suite (avast premier, but with the looks of avg and in name of avg as a manufacturer. Never have seen it this way, but seeing avg and avast are one since a while I assumed this wasn't strange)
Reset windows firewall
Let windows try to solve the problem
Let windows reset all network settings
Setting a manual IP address
Tweaking AIO repair network
-netsh winsock reset catalog
-ipconfig /renew This gives the following error . An error occurred while renewing interface ethernet : An attempt was made to access a socket in a way forbidden by its access permissions.
System restore to a point it was still working
Scanned with adwcleaner. Set the settings to reset winsock, tcp/ip, firewall. It removed some solvusoft elements.
Installed a wireless adapter since I assumed the integrated network card could be defective. Same results, It connects to my router but no internet access and an unknown network.
Safe mode with network, same result
Tried a live disc to verify the network card did work (It does)
I think that's the list.
I can't think of anything else at this moment besides a full reinstall. And seeing as this is a software problem, I not willing to take the easy way out! It should be fixable!
Any input is greatly appreciated!
