Thanks to ehMac member "Leigh: for these cool tips.
Just want to note that WEP 'protection' is easily broken these days, so you're way better off with WPA/WPA2, depending on the devices/computers that are served.
Most of us use a wireless router (e.g., Apple Time Capsule, Airport Extreme, Airport Express, d-link, linksys, etc.) in addition to a DSL/Cable modem, and set protection from there.
You should also hide your SSID ("Closed Network") so neighbours/wardrivers can't see the network at all.

Connect via ethernet
type "mymodem" into your browser
when the panel comes up, go to the top nav (that says summary, wireless settings, advance) hit wireless settings
first, rename your wireless network (make it simple all one word with no dashes etc.)
then make sure your authentication for your password is set to WEP-Open
Put a new password (again make it all numbers like a phone number without any dashes etc.)
disconnect your Ethernet cable and try going to the new network, typing in the new password.
Try this (from Apple)
Advanced tip about deleting locked files
If there are several locked files in the Trash, you can unlock them all at the same time at the command line. Follow these steps:
Open Terminal. It's located in /Applications/Utilities.
Type: chflags -R nouchg
Note: Type one space (not pictured) after nouchg in the line above, so that it ends in "nouchg ". Do not press Return yet.
Double-click the Trash icon in the Dock to reveal the contents of the Trash. If necessary, arrange the Finder window so that a portion of the Terminal window is still visible.
Press the Command-A key combination to select all files in the Trash.
Drag the files from the Trash to the Terminal window.
Note: This automatically enters the pathname for each file. This eliminates the need to individually empty multiple Trash directories, particularly when multiple disks or volumes are present.
Press Return. No special text message will be shown indicating that the command was successful.
Empty the Trash.
Unfortunately this doesn't work on my Mac Mini without the Apple keyboard. If i use Command+Option (Windows Key+ALT on my windows keyboard) withe the Eject icon in Menu Bar - this doesn't work, no response.
I'm quoting the first post in this thread here; plus I have updated the Pro Tips link below.
