Hi,<br>My friend is running 10.3.9 and twice now her wireless connection has gone down. The first time I tried most things, including plugging it directly into the router but it couldn't get an IP address from it. Also tried manual IP address instead of DHCP.<br><br>In the end, I trashed the pref file and all worked fine.<br>This time, however, I don't have the machine in front of me, and I can't work out which file to trash (it's phone support). Also, this shouldn't really be happening often, right? <br>So, can anyone running 10.3.9 check for me to see where exactly the network pref file is and what it is called? <br>BTW, she just installed the latest security update.<br><br>
