Wired connection periodically disconnects requires ipconfig /release and /renew to reconnect

I just got back into University and after a day of using the internet I suddenly was unable to visit other webpages even though I was still able to chat. I restarted the computer and the internet could no longer visit webpages at all. I got a DNS error from the browser (chrome) and the troubleshooter.

The connection comes up as "Network 3" even though It was "Network 2" when it worked. I compared ipconfig /all logs and they seemed identical when it was and was not working.

I've found two ways to get internet connection (they no longer work):

• run ipconfig /release and ipconfig /renew several times
• set a random address and have the troubleshooter fix the new found dhcp problem (before it says dns cannot fix). I checked and it said DHCP was enabled.

But either step one or two usually needs to be repeated several times before the network will change back to "network 2" from the defunct "network 3" and after an hour or so I have problems again.

I've tried:

• Uninstalling windows defender and turning off firewall (windows firewall).
• Updating Qualcomm Ethernet driver - it is up to date.
• System Restore (problem resurfaces quickly...it's possible this has something to do with windows update?)
• Flushing dns and setting dns myself (google one and others).
• Booting in safe mode with networking...didn't fix anything
• Reinstalling Ethernet Driver
• Using other ethernet cable, other wall port.

I'm out of ideas.

I'm getting these errors commonly:

The IP address lease 155.97.227.199 for the Network Card with network address 0x902B345033F4 has been denied by the DHCP server 10.0.1.1 (The DHCP Server sent a DHCPNACK message).

Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.

By the way, Operating System: Windows 7 - 64 Bit. Have downloaded latest windows updates.

Update: And my two fixes don't work any more :( .

This is now what happens when I try to Ipconfig /renew:

C:\Users\Nikko\Desktop>ipconfig /renew

Windows IP Configuration

An error occurred while renewing interface Local Area Connection : The name spec
ified in the network control block (NCB) is in use on a remote adapter.
The NCB is the data.

An error occurred while releasing interface Loopback Pseudo-Interface 1 : The sy
stem cannot find the file specified.

Update 2: So my internet is randomly working again today. The IP address I had before was a local one while the university address should start with 155...

I didn't do anything to the settings...it's bizarre that it all of a sudden works.

Thanks!

Sadly enough, I don't think it was a problem on my end and I don't know how it was fixed, it just sort of worked again after around ten days.

Sorry...
