Question Packet loss only one one device using specific programs

[Rhys556]

Hello,

I've been trying to solve this one for a while with no luck or improvement to be seen.
I am currently experiencing packet loss on a singular device within my network, This is only experienced when using the battle.net application or any games that utilize it.

The device in question is a desktop that is wired using Cat6E through a switch but I have removed the switch and the issue persists. The switch is now back in place.

The PC currently has the following components:
Ryzen 7 7800X3D
Gigabyte RTX3080Ti
Gigabyte B650 AORUS ELITE AX V2

However this issue was also present prior to upgrading to the X3D at which point it was:
ASUS PRIME B550-PLUS
Ryzen 7 3700x
Gigabyte RTX3080Ti

The connection in use is currently a 900/90 FTTC connection however again this was present on the old 350/50 FTTC connection
(Currently using the ISP router which was upgraded with the package upgrade)

Connected to this network:
2 PC's ( one of which is the effected device) both connected through separate TL-SG105E switches
2 Laptops - Wirelessly
A myriad of other wireless devices-

No other device has any issues and the impacted device only has an issue when using the battle.net software.

Using pingplotter I can see that it is reporting the loss at 192.168.0.1
However ping -t 8.8.8.8 and ping -t 192.168.0.1 were running alongside this and I saw request timeouts to 8.8.8.8 and consistent 1ms replies from 192.168.0.1

You bypassed the switch - correct? That would be an expected troubleshooting effort.

What about swapping in another known working (no packet losses) Ethernet cable?

With and without the switch.
