Yep, another one of those 10 million threads on WiFi...
I have a feeling you are using WEP encryption. You can either stick with this, or if your router allows it, switch to the better, more secure encryption methods WPA or WPA2.
The touch with WEP encryption is a little finicky. To get it to work reliably, I suggest you do the following:
1. set your encryption level to 128 bit.
2. enter your password into the router and write down the resulting hex key
3. on your touch, tap on the blue > next to the network name and then tap on Forget Network
4. tap on Other Network, enter your network name, tap on security settings and make sure you have WEP checked off
5. on the Enter your Password screen, type in your hex key
6. you should be connected to your network. Tap the blue > again to make sure you have an IP address other than 169.x.x.x.
Or, setup WPA or WPA2 encryption (select the PSK, personal, serverless edition on your router) and choose a suitably complex 8 character or more password. You can include capitals, special characters, and numbers. You can then use this password with all of your other wireless devices.
