i-pad drops internet

If the problem does not appear to be location specific then other things to check. If the drops tend to happen in a particular location in the home then maybe the signal is not consistent & that iPad is just a bit more sensitive to the drop in signal strength. At any rate please look below & check a few things out. Hopefully something here helps. If not maybe some other user has seen similar problems & has a solid line on it. I have several iPads in our home and they seem to hold really well. 

Check the Software Version & compare it to another in the house. If the age of the iPads are similar and have the same software version one would think they would behave in a similar manner. If it needs a software update, or it is pending installation then update it and see if it improves. 

Settings > General Info > About (to check the current software version)

Settings > General Info > Software Update (to know it is up to date) [15.4.1 is the most recent 15]

You can check the WIFI settings on hers & compare them to another iPad that is working fine.

If you are not technical then you could take it to an Apple store and have an "expert" check it out. Of course make a reservation to avoid wasting more time.
