Vista Networking Woes

    Well I too am having major problems with wireless networking with Vista. I
    had an old xp laptop with a Netgear (b) adapter and it worked fine. Now I
    have a new Toshiba Satellite with Vista Premium, and I've spent literally
    Two Days trying to get it to work! I have a Netgear b wireless router, with
    2 XP desktop pc's hardwired in and my laptop wirelessly (internally).

    I see there are several wireless networks in my area. Most are secured but
    there is one that is close by that is unsecure. I have, after a lot of
    problems, been able to connect to that one. But if I try to connect to my
    network, it usually doesn't work but if it does, it says Local Only (no
    Internet). Or it will say Connected with Limited accessibility.

    THe problems I have experienced are numerous. I do know that once I was
    'connected' to my network (tho limited access and no internet). Just to try
    it, I Disconnected from the network. A few seconds later I went to Connect
    To and it said there were no wireless networks in my area! I have around 8
    wireless networks in this area. So how can one explain something as simple
    as this -- several wireless networks one time, then none a few seconds
    later?? I did click on the refresh button several times, but it still said
    no wireless networks around. Besides that, several times I Restarted my pc
    with no change in connectivity (i.e. none), then one time i rebooted and it
    amazingly automatically connected to the interenet (via the other person's
    network) on startup. However previous times I had Limited access with that
    person's network.

    I've read a lot here in the newsgroup. I've tried the Broadcast flag toggle
    off/on in the registry. I did make sure workgroup was set to MSHome (like
    my other pc's). I've tried Netmagic. I have power cycled my router (more
    than once). If it wasn't for this desktop pc, I wouldn't even be able to
    access the help in this newsgroup or from MS KB articles.

    Would trying a newer wireless router (Linksys WRT54G) solve this problem?
    Could it be that my old netgear router is part of the problem? I plan to
    try a new router to see if this would solve the problem (I expect the
    Broadcast flag in registry may affect this??) but I have doubts that it is
    the router that is the problem.

    I don't like being attached to someone else's network (tho fortunately I
    don't do a lot of internet connection through that network). I would get on
    mine immediately -- if I could. But for now that is the only internet
    access I have. I feel sorry for people who don't know anything about PCs.
    How would they know how to set up a network?! (e.g. workgroup name changed
    from MSHOME to WORKGROUP, just to name one of the minor things they wouldn't
    know about)

    I hope Vista SP1 comes out real soon with fixes to these wireless network
    problems. Otherwise this new laptop I bought is just an expensive
    paperweight.

    Sigh.

    I read somewhere on the 'net that some Netgear wireless cards are
    problematic with Vista. I think Netgear has a list of their wireless units
    that are compatible with Vista.

    thanks for the feedback. maybe this linksys router will do better. It is
    currently out of stock and I will have to wait a couple of weeks for it to
    come in.

    Kim,

    I've seen this test page. If your router passes all tests except is listed
    as "SYMMETRIC", what does that mean (NAT test)? While this test page is
    interesting, it doesn't offer a lot of insight as to WHAT you should do if
    any of the given tests fail.

    For example: the VAST majority of home based routers will fail your NAT test
    as they don't support tunneling of IPV6 within IPV4 (e.g. Teredo). Nor does
    most of the existing internet infrastructure support end-to-end IPV6... So,
    if you fail that test, then what?

    In other words, how is a user expected to use the information provided by
    this test?

    Also, I note that the WinQual information currently only lists home based
    (and not business class) equipment. Is that an oversight?

    Barb,

    Thank you for the reference. I've read (and re-read again) that article
    (and the information linked there). It's less than forthcoming with detail.
    FYI: there's not a single mention of any application on this article that
    might or might not work correctly.

    "Slow Network Speeds" - but no reason as to why this might be. Vista fully
    supports IPV4 and should automatically disable TCP window scaling if the
    network doesn't support it (or doesn't it?), so how would a router not
    supporting IPV6 impact that?

    The same holds true for "Gradual Loss Of Network Speed"

    Now, "Lack of support for new features" I can understand, but no link is
    provided as to exactly WHAT those new features are that might not work
    correctly.

    The UPNP reference is certainly appropriate, but there's no explanation as
    to what UPNP features Vista requires that XP did not (in other words it says
    that Vista uses this more - but not how).

    Finally, the links provided in the references section are less than helpful
    (linking to a glossy telling me why Vista is better - but not HOW)

    TCP Window Scaling & Auto Tuning - well Vista adjusts, but doesn't
    turn it off. You have to manually turn it off (or on again).

    Open up an elevated command prompt.
    to disable auto-tuning:

    netsh interface tcp set global autotuninglevel=disabled

    turn it back on:

    netsh interface tcp set global autotuninglevel=normal

    view the states of the TCP global paremeters:

    netsh interface tcp show global


    Joe Davies has been writing about TCP Window Scaling and some of his
    articles might be interesting reading for you.
