Hi I downloaded the released 20.04 Desktop image. I get the same behaviour. With no additional cards plugged in I do not get a network. When I attach a WiFi USB - I get a wifi network It says the wired card has no cable.
On main system boot Once I plug in a USB WiFI card - the wired network and wireless become available. A bug in NetworkManager? I havr attacted to typescripts one when booted from istall media and other on the installed system ** Attachment added: "I havr attacted to typescripts one when booted from istall media and other on the installed system" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1874437/+attachment/5359213/+files/typescript-pre-and-post-boot -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1874437 Title: Intel 82579LM [8086:1502] Subsystem [1028:0498] Network driver for e1000 card not loaded on boot on beta 20.04 Status in linux package in Ubuntu: Confirmed Bug description: Hi The symptons are: I was running 20.04 Desktop Beta - everything was ok, I have an on board network card 00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (Lewisville) (rev 04) After patching on 20th April - the network dissappeard - not the device mind you.
