Ethernet Doesn't have Valid IP / Can't connect to Default Gateway

[Frankieanime158]

Hey guys, been having a strange issue. My connection will go limited, and windows troubleshooting will give me these errors in the photo.

Restarting the router seemed to fix it when it happened yesterday. It happened again while waking up my PC today, restarting fixed again, but now it happened for no apparent reason a couple hours later. Here's what I've done.

1. Restarted network adapter

2. Updated BIOS

3. Uninstalled network driver/reinstalled

4. Windows Update

5. Manually input IPV4 settings

6. CMD commands such as flush/renew, and some netsh stuff

However, literally nothing fixes it. I've heard it's a possible hardware problem? Out power randomly went out a week ago and shut my PC off, however this has happened multiple times in the past on other motherboards, but this has never been a problem until this newer X470 board I purchased. I've had it since April, so no issues otherwise.

 

Please help, extremely frustrating :/

I'd try to RMA your motherboard, but first do you have any other computers or laptops you can use to see if there is the same issue?

Probably just need to contact your ISP and get things reset on their end.

Unfortunately I'd have no PC if I did this  And nothing else on the network is affected, just me

Nothing else is affected though, only my PC. Got 2 switches, 1 Xbox one, 2 PCs, and 2 phones all on the wifi that have no issues

No idea then, I had a similar issue where only one laptop was working after a DDOS attack, had to have them reset everything.

Have you tried using different cable to the connect. could be a bad cable or connector.
