    William,

     

    Unless you agree with me, I don't see the point of your post. It doesn't contradict what I've stated. Monitoring these forums to gather information for use by Apple engineers isn't the same as providing formal technical support via the forums.

  • phonjunky Level 1 Level 1 (0 points)

    just like to say that i contacted apple care about this today and a very friendly guy talked me thru some setting changes, cache/cookie deletion, some new DNS numbers and a java download. So far so good!

    He immediately new of the connection dropping issues and problems.

    If you bought an upgrade to osx lion you do not have to pay for this service.

    Don't write the apple support off quite yet!!!!

    I'll try and keep you posted if this hasn't worked.

     

    PS I'm running imac (late 2009) with TC as a bridge to talk talk Router and airport express to stream music

    Unfortunatly to say this but I have the same problem with my wireless connection after bought my new IMac with Lion system on!

    Anyone can help me, please????

    This might help some people:

     

    Lion doesn't yet have support for 802.1X connectivity, so if your network uses that, you will have to live with the constant disconnecting(like I do at my school) until Apple updates Lion with support for 802.1X.

  • OscarVir Level 1 Level 1 (0 points)

    is possible install a third party software for connect to a wireless network without this problem??

    I guess, that will not happen.

     

    802.11x was developed to enhance the security of WEP in wireless networks by adding a authentication server and mechanism.

    The 802.11x protocol refers to a group of evolving wireless local area network (WLAN) standards that are under development as elements of the IEEE 802.11 family of specifications, but that have not yet been formally approved or deployed.

     

    Nevertheless, some vendors support 802.1X in their 802.11 access points allthought wireless LAN implementations of 802.1X fall outside the scope of the 802.11 standard.

     

    The only OS (as far as I know) supporting natively 802.11x is Windows XP since SP1. On that keep in mind that Windows XP has reached end of sale in Oct. 2010 and the support will end in 2014.

     

    I've experienced over the last weeks that in most cases 802.11x was involved in wireless problems, UK based customers had the issues and mostly with BT-Home-Hub's.

     

    And, not surprisingly, the story with BT-Hub's is common since 2007/2008: e.g. -> https://discussions.apple.com/thread/1668490?start=0&tstart=0

    Can you clarify??  Lion has 802.1x support as has OS X for some time (back to like 10.3 I believe).

     

    I assume you're talking about a specific variant of 802.1x?  If Lion didn't support 802.1x and your WiFi network was running it, you wouldn't be able to connect at all and has nothing to do with network drops.  Be a sad type of security that if you didn't have it, it would still let you connect and then eventually kick you off.......

     

    I use 802.1x all of the time at my office..

     

    AND here are some 3rd Party supplicants:

    Just an update:

     

    Changed my wifi back to the 20Hz option and Wifi has been a tad stronger. Today, whilst away from MacBook, I Airplayed from my iPhone 3GS to Apple TV (Wifi ==> Ethernet). Worked fine. Came back to my MacBook, and Wifi had disconnected. Twitter told me the last update was an hour ago - which was the time when I began Airplaying.

     

     

    Apple, this is really disgusting and starting to hold back Lion deployment in Enterprise environments where Wi-Fi is a must, not to mention how much of an inconveinance this little 'Previous Authentication No Longer Valid' error really is.

     

    A few swear words could be used, but I tighten my tongue.

    Can you clarify??  Lion has 802.1x support as has OS X for some time (back to like 10.3 I believe).

    Indeed Mac OS X supports that;

     

    For example, when you   dial a remote-access server and use EAP as part of your PPP connection, the RAS doesn't need to know any of the details about   your authentication system. Only you and the authentication server have to be coordinated. By supporting EAP authentication   a RAS server gets out of the business of acting as middle man, and just packages and repackages EAP packets to hand off to   a RADIUS server that will do the actual authentication.

     

    But, on firsthand that has nothing to do with your local wireless network and the authentication inside that local segment.

     

    If you take a look on the configuration pane (where your screenshoot is from) you may notice that all options are grayed out as long as you are use DHCP to connect your access point (wireless router)

     

    What will bring us back to the "check your network and configuration" things.

    Lion supports 8021X. Try joining an 8021.1X network and it will work fine. If you need to use Login Window and System Profile's, download Lion Server to generate the profiles needed or use IPCU to create them.

    So far this has solved my wifi connection issue: I used iStumbler to see all the wifi channels being used by networks in my neighborhood. Several were channel 6 and 11 and others. I changed it to 4 since noone was using that specific channel. No idea why, but my wifi has stayed connected since lunch time, which is the longest so far.

  • TheAmdMAN Level 1 Level 1 (0 points)

    Just a recommendation fudgebrown but can the whole 2.4Ghz 802.11g/n.  When there's a lot of interference you need to go with 5Ghz or 802.11a/n.  Notice the 802.11n on each but what I'm meaning is specifically disable 2.4 and only use the 5Ghz radio.  The 2.4Ghz band is too full now days especially in areas of high population.

     

    Remember, even at channel 4 you are getting interference from channels 1-3 and 5-8.  The only non-overlapping channels are 1, 6, and 11.  If you're lucky enough to live around a bunch of smart people using 802.11g/n only (which is hardly anyone) then your non-overlapping channels are 1, 5, 9, and 13..

     

    Check it out:

     

    http://en.wikipedia.org/wiki/List_of_WLAN_channels

     

    So again, my recommendation is do not use 2.4Ghz anything whether it's 802.11b/g or n.  Use only 5Ghz, which also gives you the realistic option of 40mhz channels and the full 802.11n speed...

     

    Thanks...

    That's a good advice.

     

    But remember, iPhone 4 does not support 5GHz and you have to use 2.4GHz 802.11n if you want your iPhone in the wireless.

    Nevertheless you can force all other Mac's to use the 5GHz 802.11n.

    Living in an area conducive to lightening I am reluctant to run a wire from my computer to wi fi-last time it cost me the computer when the lightening came down the wire.

    Trust Apple will sort out what is surely a small issue-after all its only the lion that has this infliction-the leopard was good?

    cheers

  • TheAmdMAN Level 1 Level 1 (0 points)

    Good point, forgot to mention that.  Yes at my house the only thing on 2.4Ghz is the iPhone..

     

    Thanks for the comments.
