My internet worked fine until a few weeks ago. I'm in college and I get ethernet access directly from my wall, which I run to my computer. Out of nowhere it stopped working. I hadn't unplugged anything or done anything new. I restarted, unplugged the ethernet and plugged it back in, and ran the diagnostics. It recognizes the ethernet cord (and gets a green light), but when I run the diagnostics through the network settings, it comes up with a green light for the first three items on the Network Status list, but for internet and server, it comes up red and says failed. I can't access anything online. I know it's not my ethernet cord or provider because if I plug a router into the wall, I can get wireless access, but it's slower and not as good. I want to get it back to the old way.

Can someone please help me figure this out?

    Hiya, and welcome to the discussion board.

    Internet connection problems are always a funny one, as everything might be working fine, a security update comes along and ...
    ... it stops working.
    Two things spring to mind: 1) firewall settings: it is always a good idea to turn OFF the firewall completely ON CONNECTING. After the connection is established and working, switch the firewall ON. It will then "learn" connections, e.g. on starting the browser (safari/firefox etc), a message pops up, "safari wants to connect to port 80 (http)" or similar things "do you want to allow this?"
    and you need to allow this. It takes a while but once done it's fine.
    Have a look at firewall for Tiger:
    http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh1042.html

    2) In system preferencess/ network itself, I would open up the "network", make sure, the password is unlocked, and then "assist me", which might ask you AGAIN for your administrator password. Then follow the instructions http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh1152.html

    I found it particularly useful to delete any (previous) stored networks, as - occasionally - the machine seems to "confuse" which network to connect to.
    It may take two or three attempts of the "assist me" button before you are successful (why, I do not know).

    Any good?
