A family member recently retired a Thinkpad X395 laptop after upgrading to a Framework 13. I am repurposing that device as a music player for a stereo set.
Since its intended use would have it stationery, I’d like to connect it via Ethernet to get the most stable connection. Since the X395 doesn’t have an ethernet port, I purchased a Thinkpad Ethernet Adapter (shown in the pic below) to use its internal Ethernet controller.
When connecting using this Ethernet adapter, everything seems fine at first. Pinging my router gets about 1ms of latency which is expected. However, when I started playing music in Jellyfin Media Player, the ping immediately jumped to 4000+ ms.
The same behavior doesn’t happen when using Wifi.
Yes I know I would be better off buying a USB ethernet adapter and be done with it but I still would like to find out why this is happening.
