I just put together this video that shows you how to reset your network settings on your iPad. This is also applicable for resetting the network settings on your iPhone and iPod Touch.
Resetting the network settings on your iPad or iPhone is a great way to troubleshoot any wifi connectivity problems you may be having. This is certainly not a “fix all” for every wifi connectivity problem you may be having, but it’s a great place to start.
When your iPad, iPhone, or iPod Touch is connecting to multiple wireless access points, sometimes the signals can get mixed, conflict, or otherwise not register like they did before when you were able to connect successfully.
So if you find yourself having trouble connecting to a wifi network that you previously have been able to connect to, then go ahead and try resetting your wireless network settings on your device and see if that doesn’t do the trick.
Let me know in the comments below if you have any questions, and also let us know if this fixed your wifi connectivity problems.
