Hi, Steven!
No, I couldn't solve this problem. Every time I need LAN I have to reboot my
netbook. Also, I discovered, that if I suspend the operating system (by closing
the netbook), unplug cable and resume, the system is not crashed: it crashes
only if I hot-unplug the cable.
It is definitely a bug and should be fixed... Please provide information
about your hardware - maybe it helps developers to fix the bug.
Run:
lspci | grep -i net
In my case it returns:
01:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8040 PCI-E
Fast Ethernet Controller (rev ff)
Also, determine BIOS version by running:
sudo dmidecode
First lines of the output, in my case, are:
SMBIOS 2.4 present.
17 structures occupying 818 bytes.
Table at 0x000FC520.
Handle 0x0000, DMI type 0, 24 bytes
