Changing 169 ip address in Vista

February 18, 2008 at 10:46:22
Specs: Vista premium, N/A

So I recently had a BUNCH of problems with my network for the past 2 months. I was constantly on forums [came across this, and liked it most] and it seemed impossible to fix my problem.
After a while of messing around, I finally figured it out.

No computer would connect on my internet, but they would elsewhere...

No one knew how my IP addresses got changed to a 169. nor how to change them. Not even technicians? HA-HA!

I have a windows VISTA, and this problem is really rare, but I just want to post how I did it for others who may have it happened to them too.

Then to the first option NETWORK AND SHARING CENTER.

You will see that your computer is seeing the network, but it will not connect to the internet...
This is your problem.
First, go down to your connection where it says VIEW STATUS.

Then click on DETAILS.
If you are getting a 169, then this is what you need to do...

If you have a Router, hook up your Modem to your Router with a ethernet cable, then hook up your Router to your computer with another ethernet cable.
If you do not have a Router, don't worry, just do the "Change modem IP" only.

You will now have 2 networks, it may say "unidentified network".
Back to "view status" for your Modem connection, click on PROPERTIES.

Go down to your IPv4 and click on it.
Then below is 3 options, click on the 3rd [Properties].
Then to "Use the following IP address"...
Yours may be different than mine because of location, but you can obtain both the IP address and the DNS server from your ISP, sometimes even online if you have another computer that connects to the internet somewhere else.
After you enter all the right information, Click okay.
It will ask you to save, of course, click yes.
Go back to VIEW STATUS and then DETAILS, your modem should be holding the correct IP address and not a 169 anymore.

If you do not use a Router, then you do not need to the next step, or hook up a Router.

NOW to your Router...
Do the same steps as above.
The IP address should match the CORRECT Modem ip address.
If not... go to VIEW STATUS, PROPERTIES, IPv4, PROPERTIES, OBTAIN IP ADDRESS AUTOMATICALLY, then that should fix your problem...

I was easily amused when this took me 5 minutes before my class... when tech support in stores and on the phone couldn't even do this...

azombieee I don't think you are clear on what you were trying to solve nor the methodology to accomplish it.

a 169.254.x.x ip comes from having the nic configured to get a dhcp ip [auto assigned] but wasn't able to get a response from a dhcp server so it defaulted to "auto assigned ip address" setting in the advanced tab of tcp/ip config.

You don't "change the modem ip". You get a ip from the modem [actually if a modem you get it from the ISP's central dhcp server - the modem is just a pass thru device]

Your last paragraph concerning a router... has nothing to do with the modems ip. That is what the wan port on the router gets not the pc. Setting the pc to "OBTAIN IP ADDRESS AUTOMATICALLY" only works if you configured the router to give out dhcp ip.

To solve a 169.x.x.x resultant ip you have to understand how dhcp works and then figure out why the pc wasn't able to contact the dhcp server.

Imagine the power of knowing how to internet search

Zombie, what worked was you changed the NIC to obtain the IP Address automatically (Using DHCP.)

Life's more painless for the brainless.

Ohh alright.
Well I had it doing that first, but it was only reading 169.
I tried everything before. So pretty much, what I did, did actually change it all.
