conflict IP address problem

I bring my new laptop to my cousin's house (spec at my sig).

And I got "conflict IP address" problem

I found it on internet but it just worked around in 30 mins, and I saw the happen again

 

If the notebook is getting conflicting IP addresses, is your cousins network setup for DHCP? Or is everything static? If it's DHCP, try this...

Click start, type "cmd" into the search box and hit enter.
now type:

(after entering that, you should see it release all active IP addresses)

(now it will renew all DHCP leases on all adapters)

 

how many DHCP addresses is your cousin's router set up to provide? Perhaps they have restricted it down to too little?

 

or, the machine you are bringing in has a static address that conflicts with your cousins IP addy pool.

many things can cause IP address conflicts. That you have one is not the important thing. The important thing is that you find out the cause.

 

My knowledge is "conflict IP address" is problem about two laptops are the same IP.
I changed my IP on my laptop (I just used 1 IP address) and my cousin used automatic IP address. Then, that did not work. I don't believe from 192.168.1. 2 to 192.168.1. 254 , that's so many IP, but we got the same IP.

However, my cousin has two laptops, and they work well. No any problem about IP. Just me, bring my laptop to his house. And any laptop cannot connect to internet.
When cousin's laptop was disconnected, or turned off by him. That time, I could connect to internet via my laptop.

[Question] Why cousin's laptops (two laptop) don't have any problem. Both of them get an IP address automatically.
My laptop get obtain an IP address automatically (did not work), and change IP did not work, too.

 

192.168.1.254 is usually a DSL gateway's config page. Therefore you can't assign your notebook this IP. If your cousin has DSL with a standard modem, your router will have to be on a different subnet, for instance an IP would be 192.168.2.42. If you have cable .1.254 is usually the config page for the cable modem as well, so you can't use that there either. With cable though your router won't have to be on a different subnet. With cable the addresses you usually can't pick are 192.168.1.1, and 192.168.1.254.
