So I have bought my first Linux computer. No Windows on it at all!

I am trying to use it as a local server. Apache is installed and some folders shared.

It works perfectly fine for somewhere between an hour and four hours but then it just stops responding.

Here is information so far:
*) Resetting the router (and only the router) will correct the problem
*) Resetting the Linux computer (and only this computer) will correct the problem
*) The Linux computer (and all others) can still connect to the internet. Apache still works on the Linux machine (localhost works fine).
*) I can't get to the computer via it's name or it's IP address
*) I've given the computer a fixed IP address but no change
*) There is no anti-virus or firewall on the Linux machine, unless Ubuntu 12.10 comes with one as standard.

This makes me think that the problem is the Linux computer. Resetting it makes it work. The router is fine with any other computers talking to each other - it is just the Linux machine stops responding.

Why would it drop the local network but not the internet connection through the same router?

How can I find out why it has stopped working?

So far, I have managed to fix every problem by searching on the internet but not this one.
