How to change your ip address with a laptop?

Question

I have a wireless laptop im connected with DHCP. How do I change my IP Address? And if I do, will I still be able to connect to the internet from the same wireless connection Im using right now?

Sorry If this doesnt make sense, I dont really know much about this(: thank you

Answer 1

To change your IP address you would have to turn off DHCP and then put in your network settings manually. If you are running your own wireless access point then this shouldn't be a problem, but if you are connecting to a public access point, or one you don't control then you really should leave it on DHCP. As long as the settings you put in are correct then you should still be able to connect to the Internet.

Answer 2

If you are connect via DHCP then you cannot change your IP, because your router tells your computer what its IP is.

You may, if you wish, set a Static IP (manual) however you will have to research more about your router to make sure you will stay connected. Many routers reject static IP address, unless told otherwise, so make sure you modify the proper settings on your router if you wish to have a static IP.

Answer 3

If you are on a network using DHCP, you do not need to assign an IP address. connect to the wireless connection and then right click the wireless signal in the system tray and click repair. This will release your ip and renew it. Once it renew the dhcp server will assign you an Ip address which in turn, allow you to hop on the internet.

Answer 4

You can switch it to manual, but why? It's a little complicated and don't want u to **** something up. Control panel - network connections - right click on local area connection - properties. Click on Internet protocol - properties. Manually insert your desired settings. NOTE - you may input what you think are acceptable settings but may not be. Don't mess with it any more than you have to.

Answer 5

some routers will put you on an IP that is, more or less, unchangeable.  otherwise, open up a notepad document and put in this:

@echo off

ipconfig /flushdns

ipconfig /release

ipconfig /renew

proxycfg -d

proxycfg -u

@echo on

save it as a .bin file, and then double-click it.  it will reset some of your settings and request a new IP address.  depending on your setup, you might get a new one every time, or sometimes, or never.

Answer 6

I agree with the other contributors that this is not to be done lightly, if one wishes to maintain connectivity.  And do tell, WHY do you want to do this?!?

That said, please take note that when Will J said: "Many routers reject static IP address, unless told otherwise"

that's absolutely false.

Routers have no knowledge of where a host derives its IP address.  If you statically assign an IP that's part of the valid DHCP block for that segment, it will work (assuming, of course, that you retain all other working parameters such as gateway, DNS, etc).  

If a router is configured to only allow routing of packets sourced from a certain address block, say the one allocated by the DHCP server, then it will route the packet regardless of how that IP was allocated.  It cannot reject the packet because that host configured its IP statically.

A valid risk in such static assignments is that you can cause an IP address conflict if the DHCP server itself tries to lease out that same address.  However, a well-behaved DHCP server (or on-segment DHCP relay) will do a gratuitous ARP to check if any host is using that address before it makes its DHCPOFFER and "stand down" (rather than cause an actual problem by adopting a duplicate).  It will then log a warning and/or issue an error dialog.

As far as your wireless still working after you change IP, yes it will as long as you're still associated to the same AP.  (Wireless is layer 2 whereas IP is layer 3 ... if you don't get the "layer" thing, just ignore this statement.)

Let me know if you want any of the foregoing explained further.
