Periodic loss of connection: iPad DHCP client may be wiggy
Symptom: signal not weak, but iPad periodically becomes "not connected"
Workaround: go to settings, find the network, and connect to it.
Note: password is not being forgotten in this case.
I think my iPad is having problems when it's DHCP lease expires. It does not appear to be renewing its lease gracefully. Instead it winds up disconnected.
The DHCP lease expiration is a theory, but it seems to fit. I noticed that disconnections happen about once per day, which corresponds to the 24 hour client lease time as set on my router.
Checking the router's lease table, I also saw that several devices were renewing at about the same time, which perhaps also contributes to the problem. Potentially, there could be a brief conflict when this happens When there is an IP conflict, most other devices will just request a new lease. But I figured I could prevent this by manually renewing the iPads lease so that it would have a new renew cycle.
This morning, I happened to be using it when it was due to renew it's lease. I was browsing the web, and sure enough there was a momentary "connecting" popup, but I did not get dropped..
I am going to try a static IP next.
