Just encountered this issue. If the router is configured to 5GHz bands 149-161, the Wi-Fi intermittently drops off, preventing even normal use of the iPad.
Changing 5GHz band to 36 solves this issue as of now. So far did not encounter this problem on 2.4GHz Wi-Fi.
Reported this to Apple including solution and instructed them to report this to their hardware team.
