Samsung galaxy tab 2

[The_Mowgs]

What is the latest stable build for the tab2? My tab is giving me endless problem like wifi disconnecting for no reason, not being able to connect to wifi and speeds between router and tab extremely slow.

I dontt have the tab with me at the moment but I think I have version 4.0.x. I connected via kies but no update available.

Hope someone can help or point me in the right direction.
