intel i219-LM in CentOS 7, the network speed is low

Post by lonfee » 2022/08/08 04:58:29

I have a dell optiplex 7000 mmf pc. when i install centos 7 to this pc, the network speed is olny 100kb/s(test by download a file), and network packet loss is serious.
but when i install windows to this pc, the network speed is 30MB/s(download same file with centos), and the network is stable.

Why is that?

Best regards, many thanks for your help

Please show output of lspci -nn | grep net

I have on HP Z2 G8 (Xeon W-1350P) a different(?) I219-LM that the e1000e of CentOS 7 does not support at all:

Code: Select all

lspci -nn | grep net
00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection (14) I219-LM [8086:15f9] (rev 11)

And the output from uname -a
The future appears to be RHEL or Debian. I think I'm going Debian.
Info for USB installs on http://wiki.centos.org/HowTos/InstallFromUSBkey
CentOS 5 and 6 are deadest, do not use them.
