iPad mini was working until around 6 PM, where it just stopped connecting to wifi and internet just stopped. Tried all methods that was discussed in the past post, including turning off the router off for 30 seconds and on again and then going to Settings>General>Reset>Reset Network Settings, Forget this Network, hard reset, putting the iPad in airplane mode and out, resetting to Factory Default, etc. The connection is not limited to just my home wifi network, but it would not connect to my local Starbucks, school wifi, or even my friend's house. What would be the best course of action? The iPad mini is out of warranty, and it was purchased immedietley after it came out, and the nearest Apple store is 70 miles up north in Portland, OR. How much would the repair estimate be if the wifi chip needs to be replaced?
