Problem is that the ethernet port is extremely slow. about 100kbyte/s download throughput while on a gigabit connection. Upload seems to work just fine. Also when I pxe boot the system it's also painfully slow. But here comes the funny part. When I attach a usb memory stick the throughput of the networkcontroller is as expected. I've used latest ubuntu 20.04.2 kernel 5.8.0-55 I've used latest ubuntu 20.04.2 kernel 5.10.0-1029-oem Turns out this problem is not showing up when I manually install the 5.8.18 kernel. Also when I create my own iso with the help of Cubic and install the 5.8.18 kernel in it the pxe boot is working as expected with high throughput system: Dell latitude 5420 + 5520 nic: Ethernet Connection (13) I219-LM ubuntu 20.04.2 module: e1000e Please assist.
