Buffering wifi

Try the following. Stop at any step that solves the problem:

1. Toggle Airplane Mode OFF, then ON.
2. Reset your iOS device's Wi-Fi settings: Settings > General > Reset > Reset Network Settings
3. Perform a "Reset All Settings" reset: Settings > General > Reset > Reset All Settings
4. Reset your iOS device to its factory default settings: Settings > General > Reset > Erase All Content and Settings (Note: The following will erase all of your data and media and resets all of the iOS device's settings. You will need to restore it from a previous backup from either iTunes or iCloud.)
5. Make a Genius Bar appointment at your local Apple Store or take it to an Apple Authorized Service Provider.

How about providing us with some additional details so we can assist you with this issue ...

... like:

• What exact model is your iPad and which version of iOS is it running?
• Has this always been an issue or just started happening? If the latter, did you update anything on it?
• Does this issue happen regardless of which Wi-Fi network you connect it to, or to only one specific one?
• What have you tried, so far yourself, to resolve this, other than just posting here?

Didn't ask that one, but ok. I'll wait until you can answer all of my questions as I will need to know that info before I can assist you with a potential solution. If you don't understand them, just let me know.

Ok, what about answers for the other questions I asked? ... and by "suppliers" do you mean whom is providing you with a wireless network?

Please read my questions.
