Sudden Network Issues

minirhyder

Hello!

I upgraded my PC a little over a week ago (new mobo, CPU, GPU, RAM).
Everything was going smoothly until today, when I ran into an issue where my internet doesn't work sporadically. One minute everything is fine, next minute nothing loads, ping is through the roof, major packet loss.

Here's what happens when I ping a site

And here's the tracert

Things I've tried: flushed DNS, updated network drivers, set a static IP.
No effect. I don't have any software running that would cause this.

Please help :x

Could just be an issue with your isp. Have you tried using Google DNS and pinging google.com? Do you use a wired router? Does it have filtering or a firewall?


Google DNS

8.8.8.8
8.8.4.4

Not familiar with that particular traceroute tool you're using. Is that PL column packet loss? If so 79% packet loss from your PC your router is huuuuge.
Frankly any packet loss on the first hop on a time span that short is a bad sign.
It could be the Network Interface Card integrated into your new mobo is shoddy. PCI NICs are super cheap if you don't have one lying around. Like, 11 bucks at NewEgg.

Might also be a bad cable. I had one that was fine until I moved my PC to a different spot on my desk. Changing the angle was the last straw for the connector apparently because it was terrible after that until i replaced it

This is only happening on the desktop, which has a wired connection to the router/modem. I have a bunch of devices (phones, laptops) connected via WiFi and not experiencing this issue at all.

Prior to today, the same setup wasn't causing any issues, so I'm not sure what could have changed other than my hardware. I'm already using Google DNS (when I set up the static IP). Same thing happens when I ping Google.
And yes @Tofystedeth PL is packet loss %

You changed motherboards - that means you changed network cards. After you check cables / swap for known good cable, I'd test with an external wifi adapter just to be sure, update your NIC drivers on the off chance something might change, and then you're really looking at returning your motherboard because the NIC is flaky.

Sucks dude.

Check because it's easy:
*Network cable
*Ports in the back of the router
*Router firmware (version vs most recent)

I'm pretty sure you did part of that already.

Seems like it was indeed a bad NIC. Bought a dedicated one and looks like the problem's solved. Thanks for the help!

Just remember to block off the unused port so a couple years down the line you don't space out while moving your workspace and plug into the wrong one. Not that I've ever done that.
No sir.
Not me.

Well, never mind, internet issues persists.
Replacing the cable now, and then....the router, I guess?

should've started with the cable, broheim! Always check the cables first.

The new NIC was half the price of a new cable, so I went in that direction first. I need a long cable (got a 45m) to span most of my apartment from the living room to the room with my PC.

Have you tried a different port on your router?

Also, it doesn't invalidate the rule. Switch router ports, then take your PC into the living room and see if you have problems with a new cable!

Well, new cable, new NIC...slightly different problems.
Now my ping is high. Between 100-200ms when pinging Google.

Looking at your traceroute, these issues appear to be occurring at the second hop now, is your router a modem/router or is that second hop your modem's public address? It looks like your ISP's node, I would yell at them a bit and see if they can do anything on their end.
