    The symptom is like that of Limited or No Connectivity. Without going around the bush, can you provide details of your ipconfig /all?

    Looks like your DNS server ip is not correct. Your ISP should feed the DNS ips automatically and this is not the case. That 192.168.1.1 is your router's ip which is your gateway ip. Unless some settings has been implemented by your ISP you will not be able to get out to the internet.

    Are you doing the ipconfig from when it's all working?

    well this line is from when its conneted, its connected now through luck here :

    Microsoft Windows [Version 6.1.7601]
    Copyright (c) 2009 Microsoft Corporation. All rights reserved.

    C:\Users\user>ipconfig / all

    Error: unrecognized or incomplete command line.

    USAGE:
    ipconfig [/allcompartments] [/? | /all |
    /renew [adapter] | /release [adapter] |
    /renew6 [adapter] | /release6 [adapter] |
    /flushdns | /displaydns | /registerdns |
    /showclassid adapter |
    /setclassid adapter [classid] |
    /showclassid6 adapter |
    /setclassid6 adapter [classid] ]

    where
    adapter Connection name
    (wildcard characters * and ? allowed, see examples)

    Options:
    /? Display this help message
    /all Display full configuration information.
    /release Release the IPv4 address for the specified adapter.
    /release6 Release the IPv6 address for the specified adapter.
    /renew Renew the IPv4 address for the specified adapter.
    /renew6 Renew the IPv6 address for the specified adapter.
    /flushdns Purges the DNS Resolver cache.
    /registerdns Refreshes all DHCP leases and re-registers DNS names
    /displaydns Display the contents of the DNS Resolver Cache.
    /showclassid Displays all the dhcp class IDs allowed for adapter.
    /setclassid Modifies the dhcp class id.
    /showclassid6 Displays all the IPv6 DHCP class IDs allowed for adapter
    .
    /setclassid6 Modifies the IPv6 DHCP class id.


    The default is to display only the IP address, subnet mask and
    default gateway for each adapter bound to TCP/IP.

    For Release and Renew, if no adapter name is specified, then the IP address
    leases for all adapters bound to TCP/IP will be released or renewed.

    For Setclassid and Setclassid6, if no ClassId is specified, then the ClassId is
    removed.

    Examples:
    > ipconfig ... Show information
    > ipconfig /all ... Show detailed information
    > ipconfig /renew ... renew all adapters
    > ipconfig /renew EL* ... renew any connection that has its
    name starting with EL
    > ipconfig /release *Con* ... release all matching connections,
    eg. "Local Area Connection 1" or
    "Local Area Connection 2"
    > ipconfig /allcompartments ... Show information about all
    compartments
    > ipconfig /allcompartments /all ... Show detailed information about all
    compartments

    Just realized you are using this as your wireless connection.

    WNDA3100v2 - RangeMax Dual Band Wireless-N USB Adapter.

    Does the usb dongle come with a configuration software that you use to change settings. you might need to look it up cos your DNS setting might be the cause.

    Whether you are able to connect to the internet is largely depending on the DNS. Check in the Security section that you have selected the type of security that matches your wifi security for the router. Sometimes you think it's correctly set it might not be and drop outs can occur because of this.

    ISP Modem --(DHCP)-- > Router----SSID/Security----> your pc.

    Do you have another machine (laptop) that has built in wifi adapter that you could test the network with?
