If I boot from a Ubuntu USB live stick, everything works perfect on our belinea o.book 1301, but if I install Ubuntu from this stick with completely wiping the harddrive I end up with no wifi, touchpad and no USB support. Not even a USB-Stick or Mouse is recognized. and the Network-card neither, so I cannot install new packages at all.
But all these things work in the Live-System from the USB Stick! I tried all Ubuntu 16.04, 17.10 (17.10 is worse: there is no correct display settings either although it is perfect in the live-stick too) and even 18.04 beta.
Why isn`t the USB stick installing the same version on the system?
lspci |grep -i net:
Ethernet controller: Realtek Semiconductors Co., Ltd. RTL8101/2/6E PCI Express Fast/Gbit Ethernet Controller (rev 02) Network controller: Realtek Semiconductors Co., Ltd. RTL8187SE Wireless LAN Controller (rev 02)
Output in the USB-live-system of
modprobe -c|grep rtl818x
alias pci:v000010ECd00008180sv*sd*bc*sc*i* rtl818x_pci alias pci:v000010ECd00008185sv*sd*bc*sc*i* rtl818x_pci ...
In the installed system I get no output so there seems there is no RTL drivers installed.
I found some hints on this page, but that seems really hard to install without internet connection.
On the Realtec drivers page, there is only a driver for the old kernel 4.7. ;(
Note: solving the problem for the laptop of my friend is one thing, but I'd rather find a solution how to solve this for everyone:
How do I copy all drivers from the USB live system on my computer?
