You must not be connected to wifi.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are drooping internet connection)
• Launch Settings app
• Tap on Wi-Fi
• Tap on the blue arrow of the Wi-Fi network that you connect to from the list
• In the window that opens, tap on the Renew Lease button

Unable to Connect After iOS Update - saw this solution on another post.
Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.
Wi-Fi or Bluetooth settings grayed out or dim
If any of the above solutions work, please post back what solved your problem. It will help others with the same problem.
Sorry maybe I wasn't very clear.
I don't have a problem with internet connection or wi-fi.
I can access facebook okay but am unable to upload photos. This seems to have happened since I downloaded page manager for facebook. I have uninstalled it & restarted ipad but problem is still there.
I did not have this problem before.
With i messages, I can't send or receive. This feature used to work but recently stopped. I have checked settings and they appear to be okay.
You were clear.
Have you tried turning Messages off and resetting your iPad, then turn Messages on again. Settings>Messages>Off. Reset your iPad.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
Go back to Settings>Messages>On. See if that helps.
Yes I have checked that also.
Firstly I had no problem sending or receiving messages before, this is just recently. I have internet/wi-fi okay. The people I am speaking with are all signed in to messages.
I have checked my setting in messages, time, turned messages off & on, turned ipad off & on, reset ipad. I have looked at apple troubleshooing but can't find a solution.
The second problem I have is since I downloaded page manager for facebook I can no longer upload photos from my ipad to my status.
I have uninstalled and restarted ipad but problem still exists.
Would appreciate anybother suggestions.
