    Aplogies to "help needed" - I suspect it was me who originally banned this post as spam when I saw the expression "my wifi network" and misread it as "my wifi router" which is a subject of masses of spam posts. My apologies.

    The Autoconfiguration IPv4 Address. . : 169.254.245.253(Preferred) means that your device is not being assigned a valid IP address via DHCP - addresses starting with 169 are "autoconfigured" by the device when DHCP fails)

    Suggest you:

    1. delete the Wireless LAN adapter Local Area Connection* 4.
    2. Remove IPv6 from the Qualcomm Atheros AR9485WB-EG Wireless Network Adapter

    Restart and check the IPv4 address assigned to the device to see if it is still beginning with 169.

    1. Goto control panel, view by large icons, network and sharing centre, change adapter settings, delete local area conection 4.
    2. Goto control panel, view by large icons, network and sharing centre, change adapter settings, right click on wifi, select properties, clickon networking tab, scroll down to tcp/ipv6 (NOT 4). Uncheck the box at the left of it.
    3. Scroll all the way back out and reboot.

    If stillnot sorted attach a new copy of the ipconfig report.

    It's probably referred to as Local Area Connection* 4.

    That certainly isn't reflected in the text file you attached to your previous post.
    IF it is disabled now then could we please see a config file that reflects that?
    AND
    I'm not sure what this is
    Ethernet adapter Local Area Connection:
    Connection-specific DNS Suffix . :
    Description . . . . . . . . . . . : Remote NDIS based Internet Sharing Device
    But you might want to try disabling it.
    If your primary concern is you wifi connection then narrowing the focus by eliminating extraneous devices like wired Ethernet might at least help to concentrate the diagnostics.
