Q: Wifi Constantly Dropping in Lion

Yes it did sound like a scripted response, seemed to work for me, although it is limiting in the sense that I have to now be on a different profile than Automatic. I'm not sure whether adding additional wifi networks will cause a problem or not. This is better than it not working at all I suppose, but Apple should release a fix for this, it seems long overdue for many other less lucky people.

I'll be very surprised if the issue doesn't come back in a few days.

Well I'm giving it a try.  I'll reboot after I change  the location.

Does anyone have the command line from Snow leopard that people used to fix this same problem as lion.  I can't remember if that's what worked for me.

Just downgrade from ML to snow leopard. **** fustrating to have that wifi issue. Apple, please do something. Thanks.

Have you tried... increasing the time before your screen save starts?.. and on MacBook in the Energy Saver preferences....increasing the time until the MacBook sleeps.. and display sleeps? I saw this while searching for a fix to the "connection timed out' issue with my wifi.

I think mine has disconnected while I'm typing or reading.

my problem was also while typing or reading.. Hope this may help.

I had serious problems with wifi after mountain line upgrade.  I could only connect for a few seconds.  Even ethernet cable did not solve problem.  After many hours, here is what worked.  It turns out that my airport extreme was being overridden by my cable modem/router.  The modem was generating a private ISP and airport extreme was acting as a bridge.  This was no problem at all with previous OS, but mountain line will not allow this.  I called my ISP, Bright House, and from their office they reset my cable modem to bridge mode.  Then, I went into airport utilities, network, and deselected the bridge option and instead seleced DHCP and NAT.  After rebooting the cable modem and airport extreme, everything worked great.  I knew it was an in-house problem because wifi was working great during a recent road trip.  I may not be explaining all of this to the satisfaction of the technical folks, but now I have fast, reliable wifi.

This is a great illustration of how some peoples problems are not "the apple problem"!  Without seeing the exact settings before, and after, it's hard to guess what was going wrong.  It sounds like there may have been two different devices doing DHCP, and your computer may have been handed an invalid address.

If this is happening to others, you might check your router, and see what it sees as it's WAN address vs what IP address your computer is using when WiFi is working, vs when it is not working.  If you see a different "address", or "network" (different first 3 values, XXX, YYY and ZZZ in the XXX.YYY.ZZZ.UUU address), when it is working vs not working, then perhaps you have a duel routing issue, as this appears to be.

I consider it apple's problem when their software forces me to change my hardware settings  just to make this upgraded mac work when everything else including a none up graded mac work fine just fine without any changes.

I just reinstalled ML and we'll see if that works.  My next try will be a usb modem.

We can have all kinds of arguments about whose at fault, and if that's all you are worried about, then you should just get on the phone with Apple and chew them out, instead of being on this user forum, which is not a support path for Apple's products.

In the end, WiFi is just another kind of "wire" to get packets from point A to point B.  If your equipment is not capable of receving the packets, sent by Apple products, or it can't send packets which Apple products can use, reliably, then it might be something you get to deal with, like it or not.

I think there is, in fact, some work Apple needs to do, to either improve error handling, or at least use a "more linient" mechanism to downgrade your connection to use a configuration that will work.

There are lots of people not having problems.  There are lots of people only have problems with particular types of equipment (brand or technology).  If you don't want to know about how to manage the issues to minimize your lost time and money, then go sit in the corner and hold you hands over your ears and chant "la la la la la" louldly.  That will likely not result in any problem being solved, but, if that's what you prefer, then go ahead, be apart of the problem and don't worry about the problem being solved, cause it never will if that's all everyone did.

Apple has no interest in providing support out in the open on this forum, it would be admitting to the world that there is a problem, like there are many other problems with software and hardware of any kind, doing it here will just provide a window into the sausage factory. The least Apple could do is read what people are writing here and provide a fix, it's obvious there is a problem with their software/hardware.

then there's people like me that have the same problem no matter where they go or what hardware they use.

including an AirPort Express.

so my overpriced Apple router is incompatible with my Apple computer? sounds legit.

Okay, I'll say this again.  Some people do, in fact have the "Apple WiFi Problem" where they can not get any kind of WiFi connection to work.  Some people have problems related to their equipment or configuration or broken router firmware, come here, and suddenly believe they have the "Apple WiFi Problem", because well, their WiFi doesn't work.

I'm just trying to suggest that there are perhaps many people who can solve their problem without just standing around and saying "Apple fix my problem", because they don't have the "Apple WiFi Problem".

I'm sorry yours doesn't work anywhere.  Have you tried turning on the WiFi debugging?  If not, you might try that, and then when it fails, go look in the wifi log file to see what "disconnected".  It might make it much more obvious what you need to talk to Apple about fixing.

If you can't do that, then I don't know how to suggest for you to get help by posting here.
