Q: Wifi Constantly Dropping in Lion

The beta testing is actually extremely intensive, and you are the first person I have known to have a problem.

Anyone with this issue install Mountain Lion?

I have had the problem for months with a 2 year old iMac and I finally downgraded it back to Snow Leopard (which fixed the wifi issues immediately).

Of course, I would love to be using some of the new OS X features if I could just be online reliably too.

Anyone have anything to report?

FishComputer, did you have any problems with the ML install?

You might want to do a search because this is affecting even those that didn't have a problem with lion.

Well they must not be using a 2yr old mac that all ready has been updated to Lion and then Mountain Lion.  Considering all the Problems with Lion and wifi they would have beta tested a little More Intensely in that area because they sure missed it or ignored it again. 

I upgraded to Mountain Lion 16 days ago, same problems with wifi.

After 3 days I filed a bug report and was given instructions to enable debugging and get logs, since enabling debugging it's worked fine and is still working fine (it could be a coincidence but I doubt it because before it wouldn't even last 3 hours or 20 mins when playing media from network.. or 10 seconds if I tried to copy files on wifi).

I've just reinstalled today to fix SSH, so I'll see what happens with wifi this time.

anyone that does have issues: try enabling debugging with this command:

sudo /usr/libexec/airportd debug +alluserland +alldriver +allvendor +LogFile

or you can replace IO80211Family.kext with the one from Snow Leopard.

Having the same problem when coming back to my computer after being away for more than a certain amount of time. Never had this problem before upgrading to mountain lion.

Another wifi drop victim here. thinking about returning my brand new rMBP within the 14 day window with this as the reason. pretty ridiculous that something as simple as WiFi connectivity is plagueing brand new hardware and software. I for the life of me cannot understand how this kind of thing isnt simply fixed in a day at a place like Apple. Still optimistic for a patch and love the machine otherwise, so not quite willing to give up yet....

If a Retina is doing this too then Apple clearly have had no idea about the issue this last year.... Yes some tiny pockets of Apple Care do, but they aren't going to go bleating to Tim Cook about things..... What someone needs to do is email Tim's office and suggest for the good of the company that he reads every last page of this thread.

.... Furthermore, after fixing it, they then should contact every contributor here, especially the ones that say they're done with Apple, and give them a personal update, and an assurance that they will be treated as priority customers until they feel that they can trust in Apple again.

Stuff the talk of radio cross talk or interference here... Even if that is the case then the point is the hardware and software should be coping with that in exactly the same way that anything prior to Lion does. I'm totally fed up with reading the same posting time and time again saying it's probably not Apple's fault.

I continue to read this thread with abject horror. I too was tearing my hair out until I resolved my own issue, so I can't do the escalation here anymore.... Apple won't listen to someone that can't exhibit the fault anymore.

So I hope someone does email Tim.... apparantly it's quite easy as it's tcook at apple dot com

One day I hope to read that there's a fix that gets everyone back working again, and that you don't have to shell out for new hardware in doing so.

That part that will really **** you off,  Try to get Apple to admit it's their software Not a hardware issue.  My 2 macbooks side by side and only on does it.

Well, on a slightly unrelated but unsurprising issue I have yet to get the promised code for the Mountain Lion upgrade for my rMBP, but was desperate to try anything that may fix my WiFi issue. Bought Mountain Lion and upgraded, everything seemed fine for about an hour and lo and behold the issue has returned. Now i feel doubly screwed.

Not really sure what else there is to do.

And on the topic of it being a "hardware" issue and not a software issue, i am slightly confused....

they have selected and installed all the components in these machines. It may be a specific component is the problem, in this case the wifi chipset power, but quite frankly if apple is not responsible for the components they put into their machines that make up the total computer then who is?

fingers crossed but I have another week til i can get a full refund so hoping for a solution until then...

try enabling debugging with this command:

sudo /usr/libexec/airportd debug +alluserland +alldriver +allvendor +LogFile

I'm aware that this shouldn't make a difference, but after I did it worked fine. Before it wouldn't last 3 hours, so far it's been about 8 days.

Apple, ultimately will have to decide how to fix this issue, clearly.  But, if the people plagued by this, can find a work around, that certainly makes it easier to what for that to happen.

You might be able to have some leverage with Apple, if you call them every day and assert that it's not working today, and that you have X days till you can't return it, but that is your plan if a fix can not be provided.

You might need to change wifi to forget this wifi then try setting up the wifi again that it might work!

that's been suggested multiple times and is only a temporary solution (a few days at most)
