I having issues were there is long time to identify network and DHCP assigments. Clients don't release or get new IP settings when disconnect/reconnect, regardless of moving between network or VLANs. previously it was very quick to identify and assign addresses.

Running Omada Controller with ER707-M2 Router and TL-SG3428XPP-M2 switch

    Router is assigned the first address in all subnets i.e. 192.168.0.1 for default LAN

    Switch is assigned the third address in all subnets i.e. 192.168.0.3; 192.168.11.3 and so on.

LAN default Gateway is the switch address 192.168.0.3 (allows the switch to do routing for LAN network) and the switch has a static assigned address and gateway.

Static IP 192.168.0.3; Subnet 255.255.255.0; Gateway 192.168.0.1

One LAN network interface with DHCP server on router(Using assigned static DHCP reservations for all know/fixed devices)

have VLANs with DHCP server on switch (VLAN11, VLAN22, VLAN33, VLAN44) 

VLAN## Setup

Static Address 192.168.##.3/255.255.255.0

DHCP Server 192.168.##.0/24

DNS 1.1.1.1/1.0.0.1

Gateway 192.168.##.3 (Switch Static Address)

Have created static route on Gateway to Switch for VLANS

Destination Subnets -192.168.11.0/24 ;192.168.22.0/24; 192.168.33.0/24; 192.168.44.0/24

Next ho - 192.168.0.3 (Switch static address)

Any help with problem, settings or firewall would be appreciated.
