You would reboot the pc between router changes which will result in the connected router giving the correct ip lease to the pc.

Nothing strange about you changing the router and having the pc hold on to the old leased ip. You did nothing to tell the pc to renew the lease.

You can, instead of rebooting the pc, go to a command prompt and do a ipconfig /release and then a ipconfig /renew which should result in you getting the new ip from the router.

Answers are only as good as the information you provide.

What do you mean, the IP address of the previous router remains. Remains where? where do you see this IP range.

The IP address range is set in the router and there is no reason why both wireless routers cannot have the same IP address range.

well one router has ip range 192.168.1.1 with dhcp the other 10.147.1.1 with dhcp

Lets say router 0ne is connected i get an ip from the dhcp lets say 192.168.1.3

now i switch to router 2 i connect but when I type ipconfig in de dos prompt the ip address remains 192.168.1.3 instead of a 10.147... address.

That's because you are still connected to router one.

There is no way a computer with an IP address of 192.168.1.3 can communicate with a router with an IP address of 10.147.1.1 Just not possible.

It could be that you have the first router configured as the default connection and no matter what you do with router two,your computer will always connect router one if it is available. Try turning router one off and trying to connect to router two.

"why change router"

Indeed, why would you change routers, other than a laptop/tablet being used at different locations.

"if you think logic the moment you change router it could renew the lease"

The computer would have to be constantly releasing/renewing ipconfig, in order to know that the router has changed. This would not only be a waste of resources, but would be constantly interrupting the connection to the network/internet.

"do i just built a batch file"

Yes, a batch file could do what you need.

Please let us know if you found someone's advice to be helpful.

Running the windows "diagnose connection" button will do the work for you too rather than having to run a command prompt. (for those not familiar with that or batch files)

It'll reset everything too, shouldn't need to reboot. restarts the NIC completely so should renew all IP's
