Android client is deauthenticated when roaming within same subnet. This behaviour is reproducible when Force DHCP enabled.
Issue ER-4992 was fixed in firmware 9.13.3 (MR3 Refresh4) but is back in latest firmware 10.1.1.0 for ZD1200.
When Force DHCP is disabled, no issues with roaming. But this will cause unwanted clients with static IPs connecting to our network.
Background of ER-4992:
Resolved an issue where, if Force DHCP was enabled, clients would be deauthenticated after roaming to another AP if the VLAN after roaming was the same as the previous VLAN. [ER-4992]
