What is airplane mode - Dell XPS XPS10-2727BLK 10.1-inch Tablet, 32 GB

Airplane mode for 5 mins and then turn off airplane mode and try to resync

It could be that you turned *airplane mode* on by mistake. Airplane mode has to be turned off in order for wi-fi to work.

From the home wage swipe down with finger from the top of your kindle then select "wireless." You will see airplane mode on/off on the right. Select the option you want.

if its an iPad/iPhone go to your settings App and on top of the settings list touch the button to slide

That will help you turn off AirPlane Mode

If you want the WiFi to work, then yes, Airplane Mode should be off when not flying.

Settings > Airplane Mode

go into settings and uncheck the box

One option is to check your "audio profile" settings. Let it not be that you've in error activated "Airplane mode" "Meeting mode" or the likes. Another way round is to swipe from the top of your display screen down and check the icons to see if Airplane mode is activated/selected. Your tab will definitely be different from mine, no doubt. But if you look closely at the pictures attached... you will observe that my data connection is ON while airplane mode is deactivated or OFF. In order to show you, i then activated the Airplane mode and instantly, my data connection was automatically switched to OFF Hope this helps; otherwise, you need to provide additional info as regards your device please. Oops, sorry. Pictures were taken ages to upload to fixya servers and as such discontinued/cancelled by me.

Airplane mode turns off 3G and wireless etc. Good for when you are on an airplane or when you are out of range and wish to save battery.
Eg. get on a airplane activate airplane mode, switch off device, plane takes off, then when the seatbelt sign comes off turn device on, and play angry birds or watch a movie without any risk of interfering with plane.
Airdrop is a public folder, that allows you to share images, vids and links via wireless. Similar to Bump, it is less dorkier than having 2 phones have to "kiss". lockable to no airdrop contacts or everyone. See http://howto.cnet.com/8301-11310_39-57602505-285/getting-to-know-airdrop-on-ios-7/

My kids are always turning on "airplane mode" which shuts down the WiFi. Be sure the tablet isn't in airplane mode (you'll see an airplane icon) in the settings. (It's also an option at shut-down.) Being in airplane mode would prevent the Nabi from "seeing" the WiFi devices.
