1)改变网络设备MTU(最大传输单元)的值。ip link set dev eth0 mtu 1500 2) 修改网络设备的MAC地址。参数: address LLADDRESS ip link set dev eth0 address 00:01:4f:00:15:f1 3)默认情况下,所有的路由都会被插入到表main(编号254)中。在进行路由查询时,内核只使用路由表main。4...
While computer texts differ in their application of the term, Ubuntu uses the TCP Maximum Transmission Unit (MTU) to refer to the largest size a TCP packet a machine can pass over a TCP/IP networking connection. While calculating this value is relatively simple and defaults work on a majority...

I got some recommendations like changing cables, the MTU size, etc… Playing around with cables did no help, but one comment mentioned the cdc_ncm driver could be the issue, followed by another saying that updating to Linux kernel 5.14 should install the correct r8152 driver… ...
