slow network with debian 10

[jringoot]

Hello,

I have an issue with new laptops from dell "Latitude 5500" and debian 10
with this network card,
ethtool -i eno2
driver: e1000e
version: 3.2.6-k
firmware-version: 0.5-4
expansion-rom-version:
bus-info: 0000:00:1f.6
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no

I seem to be able to reach only 5-10 kb/sec

I have 4 new to install (I also had a couple 5300 and 5400 latitudes those work excellent with debian 10.2)
I notice I had the same issue with the debian bootstick version of clonezilla and not with the ubuntu version of clonezilla bootstick, I had this slowness on 3 of those new laptops 4th one I installed now with ubuntu to test

and finally I tried an ubuntu install 19.10 and there I have normal speeds: 20 - 30 Mb/sec, so more than thousand times faster.

The NIC and the driver on both systems appears the same.

Any suggestions welcome,

Thanks,

Joost

Have you tried a newer kernel version? See my [FAQ] for details.

I will try a kernel update, thanks

that's it, installed 4.19.0-7-amd64 from proposed-updates and network speed is normal

Thanks
