Ethernet NIC renegotiation problem.
Hello,
I would like to fire a bug report on Wheezy but I am not an experienced
linux user, nor do I know any of the procedures.
The problem is related to my NIC card downgrading its connection to
100Mb/s when it is a Gigabit NIC and should be running at 1000Mb/s.
The only solution that works is to reboot the machine
entirely(restarting networking does not work, in fact SSH hangs;
enforcing renegotiation via "ethtool" manually also does not work). If
done so, it renegotiates to proper 1Gb/s mode. After a while it randomly
goes back to 100Mb/s.
Restarting the router does not solve anything(only the machine). The
router is an "ASUS RT-N56U".
