How to set different IP Address for each Wireless Network?

I want to set static IP Address for port forwarding, but I connect to different network each time. For example:
At home -> I want to set it as 192.168.1.251
But at campus, I want to leave it as is, because I don't have access to the router anyway. And if I leave the setting for my home IP Address, it won't work because it has different settings etc.

So how can I do this? Does it require different program or something? Help really appreciated. Thanks.

 

I think what your looking for is settings on your router, not your computer. The router is what assigns your IP address.

Most routers give you access to see any computers which have obtained an IP address through it. It records the MAC address of each computer (which doesn't change). You can assign a permanent IP address to a specific MAC address via your routers control panel.

 

Um, I know how to set static IP Address from my computer, but the problem is even if I change the wireless network which my computer connects to, the Ip settings remains the same. I don't want that. I want the IP setting specific to one wireless network, if I connect to other wireless network, I don't want the same setting.

I am using Belkin wireless N router, is there a way to just sign an IP Address for my computer from the router so I don't have to setting my computer?

 

The PC/Laptop what ever receives the IP address from the router or access point. In normal use its a DHCP server that hands out IP's randomly from a large pool of addresses.

However you can turn off DHCP and manually assign IP's in some cases. I am not sure about how yours works but with my buffalo router I was able to assign static IP's to my stuff with DHCP still on and they were assigned based on the MAC address of the equipment. I had to do this for my Wii system to play online.

 

Assuming that the wireless network at campus uses routers that have DHCP enabled, you could achieve your goal by enabling dynamic DHCP on your notebook and turning it off on your home router; you would then provide your system with a static IP configuration to be used in the event that it cannot obtain a dynamic IP address from a DHCP server (i.e., your home router). The obvious disadvantage to that scheme is that you would have to provide a static IP configuration for every other computer that connects to your home router.

If this isn't an option, the Belkin user manual for the "N" (as opposed to the "N+") router suggests that setting the lease time for dynamic IPs to "forever" will effectively keep the same IP address assigned to each computer - you could give this a try; however, I've found that with my older Belkin G+ MIMO router the IP addresses do change even though the lease time is "forever," mainly, I think, because the assignments get reset if the router has a hiccup or needs to be powered down.

A third alternative would be to set up two little batch files that would run ipconfig in a console window to set the IP address the way you want it for each different situation - that way, your extra work would be limited to running whichever batch file was appropriate for the network you were trying to connect to.

Finally, you could replace the Belkin router with another (better) router. As ViciousXUSMC states, his Buffalo router permits the assignment of static IPs in conjunction with dynamic DHCP, so that would be one alternative to take a serious look at. Also, Belkin routers are notorious for not being good routers, as I've learned the hard way (a search on "belkin" in this forum should bring up plenty of complaints).

 

I love this buffalo router its the most friendly and most powerful model I have ever got to work with and it was dirt cheap when I got it. Utterly destroys the quality of my former Dlink and Linksys. I only use the stock firmware with it too, most people bump it up a notch and use DDWRT or Tomato. I would recommend it but apparently Bufflo have some kind of lawsuit against them and they discontinued the model I have, so now since it IS such a good model the few remaining to buy have doubled in price.

Its still worth the higher price too sadly enough, so maybe if you want to shop around. This should be the same one I have: http://www.buffalo-technology.com/p...erformance-broadband-router-and-access-point/

 

Use "alternate configuration" on your nic adapter window.

 

Depending on the router you could use reserved IP address. This will assign a specific IP address based on the MAC address. This way you can run DHCP and get the same IP address every time. I use if for all of my servers, works great.

 

Is "reserved IP address" an XP thing? I don't have that in vista.

 

Its your router/ap not your computer that does it.

 

Well, averything must be done at the nic level, because Karen doesn't have control on the campus router, does she?

 

I just posted this, I think it might interest you.

Is defintely a gem, thanks. I will try it later today when I can make my laptop crash

I'll give you my feedback later, I'm actually going for a trip so it wll be the right time to try it myself.

 

Unfortunately, if the OP is using the standard Belkin N-router, it doesn't look like she can reserve an IP address for a particular MAC.

EDIT: Just came across a post in the Windows forum about a freeware app that allows a user to define several networking profiles and to then switch between profiles. The app is Net Profiles from Milner Solutions. Kudos to pascallee for finding the app and posting it on NBR.

 

My bad for trusting the seller and buying a Belkin router. Should've asked it here first. It's a new and I can't afford to buy a another one. The third time I bought a wrong router. First I bought a weird router from an unknown brand, second I bought a Linksys router but it is for ADSL while I'm using cable, third is this Belkin router.

I'm trying out the Net Profiles program now, the profile has to be activated manually but its good enough, at least I don't have to go to properties bla bla bla and set everything all over again. (Seems like this feature is to be worked on in Vista ) Thanks everyone.

Doesn't find this anywhere.

 

Do you have vista?

I'm using Vista Business.

Bad news: After I shutdown my computer and start it up again, Net Profiles messed up my settings and make my computer unable to connect to the internet. I think (I'm not sure since I don't really understand networking and stuff) the problem is that Default Gateway is always set as empty by Net Profiles even though I've set it in the Net Profiles. I then proceed to set everything manually from the IP configuration, even reconnecting to the Wireless Network, but doesn't work. Finally I disable Net Profiles wholly and restarted my computer and all went back to normal, but I'm afraid to use the program again now.

 

Did you run Net profiles as admin? If you just double clicked on it and run it as the current user, it will start but won't make the necessary change of IP. To run it as admin either right click on it's shortcut or exe and select "run as administrator" or right click on the shortcut/exe>properties>compatibility and selet the checkbox "run this program as administrator" (this will set the program once and for all to be run with admin rights), you'll have to allow UAC in both case when the message pop up.

 

I'm using the Start Net Profiles automatically or something like that, so it'll run automatically with my Windows. Is it not allowed to?

 

Try to disable the "start automatically with windows" and launch the program the way I telling you, it shoud work fine.

 

Thanks. I'll definitely try it out the next time I restart my computer.

 

Most of the time is just better to let windows to deal with getting connected to a network as you move aorund.
