In my home network, I have wireless router and DHCP server running on it. When I try to connect with my laptop to my home network, I get following IP address:

169.254.76.100
255.255.0.0

That is odd, because my DHCP address scope is starting from 192.168.1.100 to 192.168.1.199. When I restart my wireless network card, same problem.

When I run ipconfig in Command Prompt,I get following results.

NOTE: Without any problem I can connect to network in friends house!

That is a self-assigned/APIPA address. Your machine is unable to get an address likely either through a cabling/switch issue or your DHCP server really isn't answering requests.

  • Is the only thing you are changing the laptops themselves? Are you using the same cable, the same switch port, etc? Do you have any MAC filters/locks anywhere?

  • Sorry, I just noticed you are using a wireless connection. Are you you sure you are really connected and do you have any MAC filters set up on your AP?

  • I don't have any mac filters? I tried with my mobile phone, and third computer, and no problem at all, but when I try with my laptop, I can't connect !

  1. Reboot the router and PC, no connection, proceed to 2
  2. Assign your adapter a static IP address in the same range, so something like this:

    192.168.1.50
    255.255.255.0
    192.168.1.1
    

    No connection, reset to dhcp and proceed to 3

  3. Update the router firmware using a network cable from router to PC. No connection, proceed to 4
  4. Disable firewalls on PC. No connection, proceed to 5
  5. Update wireless card driver.

What is the security for the wireless? I have seen issues with WPA2 and XP PCs, just a thought.
