Usually it's because you are not making internet connection via wifi.
Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html

I have exactly the same problem.
I have full wifi coverage, can surf the Internet, get Into the app store but when I try to enter store from iTunes just get a pop up saying "cannot enter iTunes", although I can get to the podcast and iTunes u sections.
