    My z570 worked fine on my home wifi, but refuses to connect on public wifi or other office wifi.
    It works with a usb vodafone 3g dongle but won't connect to my "3 mifi" wifi (absolutely brilliant piece of kit).
    I have moved house so am in between broadband setups and out of vodafone coverage and have had to revert to my reliable old toshiba to write this do email and any browsing.
    It always connects succesfully but with no internet access,
    I have been through properties and tried without Norton and previously bit defender but no luck. pledase help :confused:
    Sony z570n win 7 64 upgrade.

    Sounds like you have manual ip addresses set. Have you checked all your network settings to make sure it's configured for dhcp, etc.?

    If you are connected, but can't connect to other machines, it's possibly a DHCP problem.

    Open a command prompt, and check the output from "ipconfig /all".
    The Wireless LAN adapter should be listed with all of:
    Ipv4 Address (that's not in the 169.254 range)
    Subnet Mask
    Default Gateway
    DNS Servers (at least one entry, possibly more)

    Also check that DHCP Enabled and Autoconfiguration Enabled both reports Yes, and that DHCP Server shows an IP address.

    If all or most of the above is missing, you probably can't talk to the DHCP server. Usually this is because of MAC address filtering on the WiFi access point, where you'll get a connect, but it won't let you talk to any other machines than the access point itself (which it will let you connect to; this is a failsafe so you can configure it and add the machine you connect from to the MAC filter list).
    It can also be because of improperly configured firewalls that don't allow 53/udp traffic, or a DHCP server that has been configured to only give certain hosts full information.
    Or even not having a DHCP server, in which case you have to enter static values.
