Strange Problem with rb450g

Hello again .

I have a strange problem . When i paste some data at terminal i get the error " Router has been disconnected"

The paste data is the default script with some modification on ips and names .

Has any “protection” about how much lines i can paste?

I add it below to see it .

Thanks in advance .

	/interface set ether1 name="Port1-Internet";
	/ip dhcp-client add interface=Port1-Internet disabled=no comment="Auto-DHCP Client";
	/interface set ether2 name=Port2-Hotspot;
	/interface set ether3 name=Port3-Hotspot-Slave;
	/interface set ether4 name=Port4-Hotspot-Slave;
	/interface set ether5 name=Port5-Hotspot-Slave;

If you’re changing the IP address, and you are connected to the router through IP then maybe you get disconnected when the IP Address is applied to the interface that you are connected through.
