Switching to a Wireless Router -- What Security Measures do I take?

I live in a condo so its possible someone could pick up my signal.

I have a firewall on my PC (zonealarm) but are there any other considerations when switching to a wireless setup?

- Change the default SID name of the router
- Turn off broadcasting of the SID
- Enable encryption (depending on your router)

That should do it for now

I knew there was a few things to do.

Are there any online walkthroughs to explain how to do these?

Enable MAC filtering as well.

Instructions will depend on the interface used by your router (most likely using the browser)

In addition to above,
-change default router admin password (and if possible, username)
-enable WPA encryption for all wireless components

Not sure if the following procedures help with security, but they were suggested to me:
-change from default channel of 1, 6, or 11
-disable DHCP and use static ip addresses
-change default ip address of router (usually 192.168.0.1)
-pick an obscure ip range for network and limit number of hosts on subnet through subnet mask

Just make sure you're using the latest firmware and as others have already mentioned, change the default router/AP password and turn on its encryption feature (WEP or WPA).

Unless you really think you need it for some reason, you should also turn off your router/AP's remote admin feature.

Everything else is sort of optional in that they don't amount to much more than a slight speedbump to anyone who's determined to break into your network.

Changing the SSID and turning off SSID broadcasting is fine, but DHCP can be pretty useful and dealing with MAC filtering is just a pain in the ass.

Set mine up the other day. Got encryption set up, no problem. Tried to disable the SSID broadcasting, but when I do that, I can't figure out how to log on with the laptop, so I turned it back on. Probably not as secure as I should be, but better than nothing.

Once you get the laptop set up, it knows the SID name and you can turn off the SID broadcasting. The encryption is probably the most important part anyway.

The encryption is the main thing to take care of. Set it for the strongest encryption possible. If they can get through that the rest probably won't matter, but changing the SID and not broadcasting it is a good idea as well.
