It appears that on one of our computers something is wrong with the ethernet chips of the motherboard, but I'm not sure. It has a SiS 730S chipset.

For the last couple of days, without any reason it just stops working and then randomly starts working after a few restarts of the computer or reinitialization of the network interface (eth0) and the route setting.

What makes me think it is a hardware problem is that nothing was changed at all. It just started happening by itself. What do you think?

I guess it might not be such a big deal overall.. I'm building a new computer anyway so my current one (with working ethernet) will go to my sisters, I'm just curious.

Thanks
