Q: Lion WiFi Connection Problem

I tried it with 'link local only' as there is no 'off' setting, unfortunately it still times out.

Go to terminal, type "networksetup setv6off wi-fi"

That will disable ipv6

BenHart67, greetings.

Has there been any progress on this with Apple? Following this and another thread, I find people trying numerous scary fixes that don't appear to resolve the problem. I keep hoping to find a system update in "Software Update" but so far there's been nothing. Thanks again for working with Apple to identify the problem and find a solution.

I tried most of the suggested workarounds - including deleting my network settings and setting them back up from scratch - but the issue always returned shortly afterwards. What seems to have permanently resolved the problem (for the last 48 hours at least) is replacement of my Time Capsule with a current model Airport Extreme. However I'm not convinced there was anything wrong with the Time Capsule and I'm certain the issue was on my iMac - probably software related, and probably related to the last Lion update.

My main reason for this assumption is the fact that none of my other devices - iPhone, iPad, MacBook Pro - ever experienced this issue while connected to the Time Capsule's wi-fi network. This eliminates all the theories about wireless interference in my view, especially given that I've had the same wireless setup with this iMac for three years with no problems.

I should also note that the main reason I replaced my router was the desire for dual-band functionality so I could have 5GHz speeds for most devices while simultaneously supporting 2GHz for devices that don't support it, like my iPhone and PS3. I also wanted the guest network feature to eliminate hassles when I have gadget loving friends over. And finally, I found myself questioning the value of the Time Capsule's integrated backup hard drive, given its high price and limited/inconvenient upgrade options as my backup storange requirements have grown.

Give this doesn't affect any devices other than the iMac why do some feel this has something to do with iPv6?

Based on the reports here, some people have the problem, others don't.  Some seem to fix the problem by changing characteristics of their network.  This could infer that the problem in Lion/the driver, occurs when something is not going correctly with the operation of the WiFi network.

If your router does not do IPV6 well, that traffic between your Mac and the router, could cause the connection to reset, and thus create problems since recovery of the connection appears to be the problem.

Others have switched to a new channel, used a fixed channel or switched bands from 2.4ghz to 5ghz to make it work again.

Others have switched routers which may have made IPV6 work correctly etc.

So, trying to change/turn on/off all features that might cause your WiFi connection to fail/work irregularly might help.

You can, of course, attach additional storage via the USB port on the back of the Time Capsule.  Also, using a Time Capsule provides you the opportunity to get support from Apple to resolve problems if the time capsule is not working.  If you turn on the system flag to allow Time Machine to use other SAMBA visible storage, then you are basically on your own about resolving problems with backups.  For some, that's not such a big deal.

Last I heard was that W&L (and I'm sure Penn as well) has been working with an Apple engineer to hopefully rectify the problem. Many people in my department are actually sharing the opinion that we won't see a fix until Mountain Lion to drive sales. I won't comment on whether I think that's true or not, but I've been out of touch on the situation since our students are out for summer. The fixes for home use here actually HAVE been working for some of the students emailing me over summer. Those same fixes aren't feasible in enterprise environments, so right now there is no known fix.

Trust me, I've been anxious to get on here the second I get word that the engineers have figured out the issue, but I haven't heard news for a couple of months. Sadly, I bet we'll all just have to cross our fingers and hope Mountain Lion is better...

Kind of like Windows 7 was basically a service pack for Vista, many of us are feeling like Mountain Lion will be the same for 10.7.

Thanks very kindly for that update, BenHart67. I'd more or less come to the same conclusion: that we'd need to await the next big cat's arrival in the menagerie. Luckly, I've been able to rig up a wired connection for my wife's computer using one of those gizmos that carries a signal through the apartment wiring, so the urgency has  eased - but the frustration lives on.

Thanks that did work to turn of ipv6, however the timeouts live on. I think I have tried every computer side solution I have read to no avail. I can't try anything on the router as it is an enterprise situation. I doubt it is the network at fault, however, because my iPad and iPhone connect fine.

I cannot believe apple hasn't tried harder to fix this with over 380k views on this thread. I called support about this and despite having an iPhone iPad and MacBook air they still tried to charge me $45 for a single call despite my AppleCare just ending recently. Their support used to be much better and I will certainly consider other options when new computer time comes around again.

Dont know if this solution is listed somewhere else in this thread. Or if this is the only solution, But here goes.

Delete wifi from network list. Remember to apply changes . Then reboot. ( I did this while connected to lan, not sure if this makes a difference or not) Then in network i added a new wi-fi service. At first my macbook complained a little with various warnings, but after a minute everything started working again. Hurray.

Hope this may be of some use to anyone out there.

I bought a macbook to avoid spending time configuring, like when using windows. But now i find it that i encounter more and more problems, which I have to fix with no support whatsoever from Apple. Only thing they contribute with is stories about faulty HW, which in most cases is obvious not true. Hope they will change their way of dealing with customers SW issues.

Removing/resetting all WiFi settings and setting things back up, has been a solution for some people.  There have been mixed results on how long that fix laster.

This thread is a good plot for a never ending story.

An ever repeating story.  Not sure about the 'good' part.
