    Wireless NIC Issue: APIPA address w/ DHCP, media disconnect w/ static


    So I am at my wits end with this issue. I have dug through a few similar threads I found on here, followed the advice, but I still have not fixed the issue.

    I have a Lenovo T50 that I have been using for about 3 years without issue. The wireless NIC has never had an issue connecting to my work's AP setup. For one reason or another, I pulled my laptop off the dock one morning, and I have not been able to connect wirelesly ever since.

    So here is my issue: When I tried to use DHCP, it will connect to the AP but my computer will assign me a APIPA address (169.254.x.x). The DHCP Client service is running on my laptop. When I tried to use a static IP, I get the same APIPA address assigned.

    Here is just about everything that I have tried to date:
    - Turning off Kaspersky
    - New wireless NIC
    - Onboard wired NIC: works with static and DHCP
    - USB wired NIC: works with static and DHCP
    - USB wireless NIC: APIPA address with DHCP and static
    - Use my phone as a hotspot and connect wirelesly, same result
    - Deleted all network adapters, restart, and let the computer find them again
    - Delete any ip routes
    - Reset the IP stack with the following commands
    Code:
    ipconfig /flushdns
    netsh int ip reset reset.log 
    netsh winsock reset
    netsh winsock reset catalog
    - Many, many, many reboots

    Nothing has worked so far.

    Here is my ipconfig results:

    And I attached my Xirrus screen shot. I really think this is a Windows client side issue, as I think I have ruled out any issues with the router or network. I am at a loss here folks, so any advice would be helpful. Thanks.

    Welcome to the forum. You say you assign static but get same 169 IP that can't happen if it's static do you see the wireless network OK and do you enter password OK any error message?

    samuria: normally, I would agree with you that assigning a static IP would not yield a 169.254 IP address, but it does. I can see the AP just fine, and connect to it without issue (see the Xirrus screen shot).

    And thanks for the welcome. I lurk on this site quite a bit to find solutions to issues. I finally had one that I couldn't figure our though, and came here for help.
