Network disconnection problem.
I have a laptop with Mandrake 10.1 Community on it. It has realtek 8139 lan built-in. Mandrake auto-detected this (it's eth0), and installed the correct driver.
Whenever I boot, it bring ups eth0, and for the first 10-20 megs (it varies, but it seems to be in that range) of transfer everything is fine. Then it stops. There is no official disconnection notice, but whatever I am transferring halts, as does all other network activity. From then on, I cannot reconnect at all. I can try the mandrake tools, or I can run "ifup eth0", or "dhclient", and it certainly seems to try to get a new ip, but it fails with no specific error message.
There doesn't seem to be anything in syslog at the point that the network halts, but I will root around a bit more.
Any way I can troubleshoot this better? Thanks.
