My Belkin Wireless won't work for my itouch?!?

Okay, so for the past week, my wireless won't work for my ipod touch. But my internet for my computer works. When I tried to connect to another open wireless network (Linksys), it worked perfectly. When I click the ">" next to my wireless network, it only has the IP Address and Subnet Mask. What should I do?!
Also, when I enter all the info for my network under "Static", it works but it's really really slow.
