I'm sorry about the issue. Was this iPad working fine with your internet modem / router device previously?
What's the brand / model of your internet modem / router device?
Does App Store app work or not?
Does your iPad work with Wi-Fi / wireless at the Apple store or at any other place?
When you connect the iPad to your Wi-Fi / wireless network name, what does it show or say?
Is another wireless device, such as a laptop, or wireless desktop, or another tablet or smartphone, etc. currently working fine with your wireless?
What did you reset?
Please reply at the box below. Thank you.
