I've had the ethernet adapter that I linked below for months now and never really cared until recently that I am getting no where near the speeds that I should see with the device. I use it on an older Intel i7 laptop that doesn't have a gigabit ethernet connection. My home internet speed is a 400/20 connection.
When I run speed tests with any of the common speed test websites speedtest.net or fast.com I am seeing download speeds in the range of 60-80 Mbps. I have tried uninstalling the device, swapping between 6 different network adapter drivers, updating various USB related drivers, changing USB ports, and changing ethernet connections (different port on the switch and different cable). The laptop with a native gigabit connection that is connected to the other switch port that I tested the "slow computer" on is seeing 400-500 Mbps normally.
Where things seem odd to me is that I can transfer files between the two laptops on the LAN and see speeds that range between 200-650 Mbps depending on the files and duration of the transfer. System resource utilization (cpu and ram) is quite low <25% on average during the transfers. If I pull data from Gdrive using Rclone with the "slow computer" directly I am seeing approximately 65 Mbps down, yet I can use the fast laptop to download from Gdrive using Rclone where I am saving direct to the slow laptop over the LAN and I am seeing sustained 200+ Mbps.
Not sure if that is all clear - but essentially the adapter seems like it is performing substantially on the LAN but really poor on the WAN. I've tried moving the adapter to a USB2.0 port on the "slow laptop" as well and was seeings similar download speeds to when it was on USB3.0 which makes me question if it isn't an issue with the laptop.
