Connected but no internet

I have a 7th generation iPad I have recently bought. (iPad 7th gen doesn't show in iPad topics so I chose 6th) and the problem is that it shows the WiFi network as connected but nothing works? I figured this isn't a problem with the router since it doesn't connect to any other network nor hotspot. I've tried correcting date and time, resetting network settings, resetting all settings and even reinstalling iOS software via iTunes from my computer. This problem is really starting to bug me and is the reason why I've lost all my data. There isn't an apple store in my area but I really doubt it's a hardware issue because it was working fine until recently. this issue is bugging me out. All my other devices connect to the wifi just fine including my iPhones.

All my Android devices work fine on it and this issue has made me lose so much data in an attempt to fix it.
