Subject: invisible network device

Hi,

I have a Terra Mobile 1512 laptop.
Only when an ethernet cable is plugged in during reset (NOT after
resume, e.g. re-opening the lid) then the ethernet device is listed in
the lspci output and usable. In all other cases it is not even listed or
detected. Also pluging it in later won't help.

When it is there, it shows in lspci:

03:00.2 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 06)

Kernel driver in use: r8169

There are no new bios-updates on the terra website last time I checked.
I also did not see any "green"-related switches in there.

My question now is: any ideas how to solve this? Or tips where to ask
these kind of questions?

Always wondered what the latency of your webserver is? Or how much more
latency you get when you go through a proxy server/tor? The numbers
tell the tale and with HTTPing you know them!
