Alright, somehow I ended up with two internet providers at the same time in my home.
This means two cables, of course.

Evrery time I have to switch between the two cables, I have to mess with the TCP/IP settings in my connection's properties.
The one requires me to enter pre-defined data manually, while the other obtains the data automatically.

Is there an easy and a fast way to switch between the two cables without having to manually do all the TCP/IP adjustments every time I try to use the alternative cable?

Thanks!

Buy a pair of routers, configure one for each ISP, have the routers use DHCP to give your computer an IP address etc.

without buying routers you can enter the static ip information into the Alternate tab in your tcp/ip settings. Primary tab would be set to auto assigned. If when you hook up to the static ip cable and dhcp doesn't answer you should default to the alternate settings.

Thanks wanderer,
I thought of adding the static IP info in the Alternate tab but the ISP with the automatic settings will cut me off if I attach any IP to their connection.
It's written in my contract.
I don't know if they can detect the static IP in the Alternate tab but I have to be cautious.


Is there a program or a script that can quickly fill in all the static IP data in the TCP/IP settings window?

You can script it with netsh.

Vladimir88 I believe you are misunderstanding both the contract and what the alternate ip tab does.

The contract is talking about putting a server like a web or game server on. Putting a static ip instead of dhcp on the main tab simply means you would not get connected to the internet thru them.

Since they are providing dhcp and your primary tab is configured to recieve dhcp you would never get to the alternate configuration when connecting to them.

When you then connect to the static ip connection, dhcp will not work and then and only then will the alternate tab ip address come into play.

Technically speaking, there is still a danger. If the ISP's DHCP server doesn't respond in time, his machine would still use the alternate static IP connection. Now, granted, it would most likely be the case that the alternate static IP config would not match their network, and it wouldn't hurt anything. However, if that is the wording of the contract, technically speaking, he has violated it.

The ISP first of all must not be very good if their only prevention of IP address conflicts due to some idiot assigning a static IP within the DHCP scope of the ISP is putting it in a contract. What about a potential hacker getting into their system?

Regardless, there's no point going down this path because no which what he does, he's gonna have to either type some commands or batch/script something anyway. He might as well script changing from a static to a dynamic instead of a ipconfig /release and /renew, although that could be accomplished by issuing a repair command of his NIC.

But honestly, the best solution is multiple routers. He shouldn't be connected directly to the internet anyway for security reasons.

Thanks guys.

Now, both ISPs are trying to preven ID theft on their networks by using VPNs.
When I connect to the ISP with the automatic TCP/IP configuration (DHCP? or whatever it is called) its VPN shows that it is connected BUT the network icon in the system try shows a triangle with an exclamation mark.
I talked to the guy from the ISP and he said that it was perfectly normal and not to worry about it - this was caused because there are no real IPs on their network and the icon is showing that triangle to indicate that it can't find an IP or somethig.
In brief - he told me that the exclamation mark must be there and that it is the way it should be.

Problem is that when I configure my connection to use the other Provider's static information in the Alternate tab and when I connect using the cable of the ISP that uses the automatic configuration, the exclamation mark triangle suddenly disappears. Apparently the connection detects the static IP information in the Alternate settings.
This is what I am afraid of - they could decide that I am assigning a static IP and cancel the contract within 24 hours (this is what it says).

Another method would be two NIC's. One configured for each provider and given a "name" to match so you don't get confused.

When you want to switch from one to another, disable the one that you're using and enable the other. Want to switch back.....disable the one you're on, enable the other.....

Good one CurtR. Though that would be the perfect time for hardware profiles with each booting up to its nic and isp config.

I wrote a program for this. You define as few or as many "profiles" for as few or as many phyiscal interfaces on your PC. Select the one you want from a drop down box, and it's done.

Wanna buy it?

What is a NIC?
Yes, I'm lame. :)


SmittyZ3M, thanks man, I will try not to buy anything until I clearly understand what is the best free option (if there is one, of course).

Aaaah, I got it.
I already have two NICs installed but the one is being used by Internet Connection Sharing.
Don't have an extra PCI slot to install a third one. :(

Sure, if you consider a direct wiring to the internet "fine". I sure as heck don't for security reasons. And don't be surprised if ICS breaks semi-often.

I don't have any servers running on my machine, not afraid of hacking attacks or something.
Security is my last concern.
I just need my internet(s) running OK.

"Security is my last concern."

Do you like your computers to remain functioning?

Do you order anything online with a credit card?

Do you care if your computers take part as tools for a hacker to attack someone else?

Do you ever type in sensitive information in any of your computer, such as user names and passwords, bank account information, etc.?

If your computers were breached and did take part in spamming or DDoS attacks, would you mind if your ISPs knocked you offline?

If you said yes to any of the above, you should be taking security far more seriously than you are.

I agree with the above.
But at this stage I am just trying to make my internet work properly and only after I do that I will take the measures needed to protect my PC from hacking.
No body can hack me online if I don't have my internet working, can they?

Yeah. i will concentrate on making these two connections work without too much setup each time I'm switching between them.

I'm not saying that security is not a concern for me. I'm saying that it is my latest concern at this stage.

I get that, but you're wasting your time. If you're concerned about your security, you wouldn't be fooling with the method you're trying. Your solution you're working to put in now would be torn down since you'd be using routers and leveraging DHCP in the routers, not DHCP from your LAN connected NIC. You'd have to change everything.

Why work to get this working when you can't use any of it to get the solution in place that actually provides the security you need?

On top of that, the weaknesses in security are exploitable the moment you connect your stuff up. So this is kinda like saying, "look, I'm just trying to learn how to cross the street right now, I'll worry about looking both ways before I do later."

Do as you will otherwise, and good luck.
