    Some P2P connections such as torrent applications may also use IPv6. I don't know the details, but uTorrent (my torrent app) has recognized I have IPv6 capabilities. I can only speculate as to the app actually using IPv6, if it recognizes the protocol. But then I'm sure the app would still work just fine without the use of IPv6. Question though, are you certain Homegroup will not work as it should without IPv6?

    Thanks for both pieces of info. That helps.
    > Are you running Windows 32 or 64-bit?
    > Looks like you have an Intel Wireless Lan card installed

    Take another look through Programs and Features. Anything about Intel Wireless in there? There may not be. But double check

    Yes. I don't use Homegroup myself but have seen that mentioned in various MS documentaton since W7 came out. Here's one Homegroup and ipv6 Troubleshooting

    OK. As you probably guessed, the P&F entry in your last post is for the graphics card. Since not in P&F, we'll uninstall using DevMgr (tip: always best to check P&F first. Uninstall the device from PF if an uninstaller for the device is provided there)

    I'm seeing 2 Wireless LAN drivers for your model. (Go to Sony support and lookup your model and OS - so you double check my work :) )

    In DevMgr, right click the Intel Wireless Lan device->Uninstall. If it asks or gives you a check box to remove driver files, do so. Then install the latest Intel Wireless Driver update from Sony site. (I'm seeing 6/30/2010 v13.1.1.1 as the most recent of the two)

    AND it's probably good to do a reboot after uninstall but before re-install

    @cliffordcooley

    p.s. If I remember correctly (I'm pretty sure but I wouldn't bet the mortgage on it :) ) MS does, at least, provide a warning if someone is using Homegroup (or tries to use it) and ipv6 disabled.

    Is this

    the intel wireless lan device to UNinstall?

    Yes, that's the one to right click->Uninstall.. Do a reboot before you re-install

    So far so good. Now just to find where on the Sony site to get the correct one.

    Go to Sony support, click on Drivers and Downloads. Enter your model # then select your OS. Scroll down to the Wireless LAN section.

    Installation is in progress :)

    Ok, you previously said you saw two. So did I. Should I now install the other one?

    Oh. no. Only install the most recent driver version. (Vendors may provide multiple version if someone wants to fall back to an earlier version)

    While you're at it, I see under Wireless category is an update for the Sony wifi utitlity. Download and install. (you don't need manually uninstall this one first.)

    P.s. if you're wondering why not uninstall the utility first as we did for the driver? I suppose no good reason other then personal habit.

    I'm more trusting of utility apps then drivers to re-install themselves correctly. It wouldn't be wrong if someone chose to uninstall the app first before app re-install.

    Just the critical update on this one. btw Click on where it says Wireless Component Update and it'll give you directions on how to install

    and I'm running for awhile... so will look back in either later tonight or tomorrow :)

    Would that not be an update to the other one, requiring the other to be installed first?

    I'll wait for a reply. I'm on the wireless right now. Removed the DSL. :)

    Good question. My instruction is based on some combination of what I've observed in the past plus some gut feeling

    From a broader perspective
    The word "update" seems to be used loosely by vendors. You usually have to read the software description to understand context and whether "update" is an "add-on" vs. a full replacement for something that exists.
    Both the driver and wifi utility use the word "update"

    > The driver description indicated it was a full replacement (rather then an add-on)
    > On the other hand, the wifi utility description indicates it's really an add-on.

    So, why not be concerned about the utility base (in this case)?
    1. The wifi utility base file on the support site is dated 2008. So it's almost certain that learnin must have either the same, if not a more recent, base already installed
    2. Application add-on updates are pretty good about checking whether or not it can be applied to the base version it finds. It should give a message if the update can't be applied because either the base is wrong not be needed if its already been applied to the base

    So, learnin', I suggest you only install the utility update. If it indicates anything other then succesfull, then let me know

    Ok, as I previously stated, I've been on wifi ONLY for over 24 hours & no connection problems.
    I will bookmark that page I saw it on & if I have problems I'll do such unless you think I should do so anyhow.
