UDP Checksum Incorrect

asked 2022-10-06 13:26:05 +0000

Hi, I try to investigate what causes serious hitreg and desync problems in all online games despite low ping. I sniffed out UDP packets while playing and this is what I got.

I found this post https://osqa-ask.wireshark.org/questi... but I am not sure if it's related. Could you verify if everything seems to be normal or if I should contact my ISP?

Yes, that post is telling you one very common cause of IP/TCP/UDP checksum errors. Are those packets being sent by the machine on which you're running Wireshark?

Yes. This is traffic to and from server I played on.

No, that's not what he's asking. He is asking "Are those packets being sent by the machine on which you're running Wireshark?". The direction makes a significant difference.

Yes, those packets are being sent by the machine on which I am running Wireshark.
