2. Scope ip : 10.60.2.0 : When my laptop, pc connect to the network via cable to SG220, the laptop, pc connected and work good, but time to release ip long tim ( about 1 munites0.

Two scope work good via orther switch .

Which ip address is the gateway for these networks?
For exemple:

for network 10.60.2.0: gateway is 10.60.2.1

Could you provide it?

Thanks in advance.

dear,

This switch layer 2, It's just have IP managerment. IP auto get infor from the network.
When I connect other network ( not 10.60.1.0), It's relaese ip from DHCP server of this network.
But, only the network 10.60.1.0 could not have ip and not effect to any device (laptop, pc) connect via SG220.
Try test with orther network from wifi accesspoint network 192.168.0.0 via SG220 work good .
Something wrong? :(
Thanks
