I can not get my WiFi turn back on it keeps saying out of range

Concerning users with WiFi issues....

Something else that owners of these models may experience, worth adding here.

Quick specs on my issue: Android 4.4.2, KitKat, July 2014 kernel, T5200XXUANG1 build (Australian); I put that in this post in case it ever helps anyone visiting the forums. Again, this is a Samsung Galaxy TabPro 10.1, model SM-T520.

My unit would only barely pick up my home router & Galaxy S5 phone wifi hotspot. It was also not picking up any nearby neighborhood wireless router & there are a ton of them. Since I hadn't removed the back yet & thought perhaps unplugging battery from motherboard may help, opened back & EUREKA! The actual physical wifi card cable was UNPLUGGED! Unclear how that would have happened but now I know why it was in such good shape & the eBay seller was letting it go so cheap.

So, certainly remove the back cover & physically inspect the unit. Amazingly, it's not always the OS, software, or router settings to blame.
