[SOLVED] Slow times on wired connection

Hello,
I'm having problems with my wired internet connection.

The actual bandwidth is fine (around 400 Mbps up and 400 Mbps down.) However, whenever I browse anything or use ping, the response takes a long time.
As a result, I can't connect to things like Discord or even the Arch repository.

Output of ping youtube.com

ping youtube.com                                                                                                             
PING youtube.com (2800:3f0:4001:808::200e) 56 data bytes
64 bytes from 2800:3f0:4001:808::200e: icmp_seq=1 ttl=117 time=7.34 ms
64 bytes from 2800:3f0:4001:808::200e: icmp_seq=2 ttl=117 time=7.40 ms
64 bytes from 2800:3f0:4001:808::200e: icmp_seq=3 ttl=117 time=7.51 ms

64 bytes from 2800:3f0:4001:808::200e: icmp_seq=5 ttl=117 time=7.40 ms
^C
--- youtube.com ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 13028ms
rtt min/avg/max/mdev = 7.340/7.458/7.638/0.105 ms

It always takes more than 5 seconds before and after the first line of ping is outputted.
That makes me think it might be a DNS problem, but nothing I've read seems to work.

Ouput of lspci -v

I have tried Google's and CloudFlare's DNS and noticed no difference.

I have tested the wired connection on another device and it works fine.

I don't know if this can be related but I also can't access my routers page from this computer. On my laptop I can though.

I'd be grateful if you guys could help me troubleshoot this.

To be honest I don't know much about all this. I set that up for a Windows VM.

Re: [SOLVED] Slow times on wired connection

I set that up for a Windows VM.

Get rid of that, see whether that fixes your problem.

You're timing out reaching the google and cloudflare servers, it's a routing or connection problem, not a DNS one.

I removed all the packages related to my vm setup and the problem was solved.
Thank you for the help.

But you don't need any of that if you just want to run a windows guest in virtualbox.
