I've tried an installed instance of Kubuntu 14.10 and the live DVD both 64bit and 32bit. Using the 64 bit version the Realtek network chipset doesn't work. It doesn't work in KaOS either. Chipset is: Realtek GbE, RTL 8111/8168/8411 Reproducible: Always Steps to Reproduce: 1. Run live 64bit DVD distro, or install. 2. Try to connect to network 3. Actual Results: Taskbar icon rotates, then fails leaving a ? on the network symbol.
Please report hardware driver issues to the bug tracker of your distribution.
