Welcome ,I will give a full and clear answer to your question, please make sure to reply to any questions I have. They may be essential to my reply.
I see the problem . ,
We need to learn what settings your need , and what settings you dont need .
On your router may be printed the detail you need .
It may be small type , so look closely .
SSID , if your routers name or WIFI name . The name of the LAN network it creates .
this is the network you want to pick when joining a network .
Password XXXXX key is the password XXXXX will be needed to join the above SSID .
MAC ID , has nothing to do with your needs .
SN or serial number , has nothing do to with your needs .
IPAD forget networks , wifiSometimes you need to renew the DHCP on the ipad .. Go to Settings / Wi-Fi Networks and tap blue arrow next to your home network. Select "Renew Lease" In the DHCP tab.
Forgetting the network can also help. Go to Settings / Wi-Fi Networks and tap the blue arrow next to your home network. This time tap "Forget this Network" and wait for your iPad to reconnect or add the SSID of your wifi routers name back in via Settings Wifi then enter the new password.I hope this helps .Thanks.
