At my university they have a large lan, and you can connect to it from your room. All that they ask is that you logon properly with your user name etc so that they can monitor whose online and how much they're downloading, not unfair seeings as us students are getting v.fast internet for free.

Now back to the problem, i bought a network card off of them and a lead so that i could set up my girlfriends computer to use the internet, i have installed the very same card on other friends computers and put the settings in and theirs works fine. But with my girlfriends one it works fine on the net for about a day and a half, and then stops. I can't log in to the lan or use the internet, but MSN messenger still works. The subnet mask seems to change to a wrong setting, 255.0.0.0. The only fix i have found is to go into winipcfg and do a release and renew, then it works again for a couple of days, then stops.

Anyone got any ideas
