samsung galaxy help please???
 

We got a tab2 10.1 a couple of days ago, its great and really happy with the buy.
Only issue is we are having some trouble when using the internet(Wifi). The Tab connects with our Sky router as long as i go into settings and turn off the security. If security is on the Tab prompts you to enter password before connecting, when i do so it says then trys to connect but reads "authenticity error", this doesn't make sense as the laptop connects fine.
Any suggestions?

Sounds like an incorrect password or upper/lower case is being used incorrectly.

Tried all that, somebody suggested these tablets wont work with certain security settings, even with the correct password it will not connect.

In that case, check that you've used the same option of WEP or WPA2 or whatever on the router as on your tablet.
