--Efter at have sat Download / Upload /Ping igang på min Plex Media Server (robin) - kunne jeg i [[splunk>>https://www.mos-eisley.dk/dosearchsite.action?cql=siteSearch+~+%22splunk%22&queryString=splunk]] hurtigt se at 100 mb var max... underligt...

--RTL8101/2/6E bør jo være Gigabit, men det virker mere som et 100 MB netkort og der er mange hits på issues med det...
--
--Linket [[her>>https://askubuntu.com/questions/892003/my-gigabit-network-card-only-getting-100m-is-it-even-actually-1gbps]] antyder dog at det er driveren der rapporterer forkert tilbage
--
--Nå, lidt Google bragte mig til: [[https://www.unixblogger.com/the-pain-of-an-realtek-rtl8111rtl8168-ethernet-card/]] da jeg kiggede mest på driver versionen: r8169
--
--Og jeg gik igang... installerede, byggede og prøvede...
--
--Absolut intet virkede og pludselig var nettet helt væk, den nye driver kunne ikke loades og den gamle kunne jeg ikke få tilbage..
--
--.....
--
--Nå, jeg fandt den gamle driver r8169.ko under /lib/modules/4.15.0-32-generic/kernel/drivers/net/ethernet/realtek/r8169.ko - men kunne ikke indsætte den, da jeg kørte 4.15.0-33-generic
--
--Så en apt-get purge linux-image-4.15.0-33-generic - og genbygning af grub's list
--
--Og jeg var tilbage... til udgangspunktet (sad)
--
--Næste forsøg: [[https://dontpressthat.wordpress.com/realtek-r8101/]]
--
--
--
--Herefter blev det legetid med en **USB Ethernet adapter**, den var uden data eller navn, men lsusb kunne give mig:

--{{code}}
--bnp@robin:~$ lsusb
