Q: Lion WiFi Connection Problem

Sorry to disagree with that you say. If I'm an Apple customer as long as you are (and I accept to pay a premium to buy their 'superior' products) I don't expect Apple to let down a part of their customers, even if it is a small one, even if your figure of 500 is ridiculously low by just looking at the huge participation to this thread, already close to 250,000 views and tis is not the only thread on the subject.

A reminder from my side: My McBook Pro with Lion wifi is OK, my iPhone with iOS 5 is OK, my iPad with iOS is OK, my iMac (end 2010) with SL was OK BUT with Lion I have the WiFi drops!

Conclusion: there is a compatibility issue between some iMac and the Lion WiFi. I understand that the customer could change the setup of his WiFi network to fix the issue, but this is not the normal pratice as all Apple user are not WiFi network expert, and a change in the setup of a network could geopardize the other devices operation.

When I saw the Q1 results of Apple this morning with a $ 13.06 billion of net profit for a quarter and a cash of $ 100 billion, I expect that a company making so much money out of their customers could devote few hundreds thousand dollars to solve the issue of few thousand of their customers who, for most of them are loyal and supportive of the company. It will be an attitude which will strenghten Apple  image, and as you mention will definitevely prevent some to compare Lion to Vista, which I agree is nonsense.

Agree,,, but what is more sad, is that I have read many posts of people talking to apple support and getting very non-respectfull answers like "we have never hear of that problem"... seriousley.... if they say something like "we know there are some issues with some ruters, we are eorking on that..." I'm sure that most users will be satisfied knowing that their peoblems will be solve....  but this customer service is quite weird, an like i said, non-repectfull....

i found a link with many fixes for this problem.... the last one worked for me (Add a New Network Location) ....

I will continue to help to find a solution. Just give me few more days, I'm trying to connect two routers between them and see if it works. The idea is to avoid lion beeing connected to the wi-max router of the local internet provider, disabling wi-fi and then connecting it through a cable to my new tp-link router and, from the last, connect to the MBP wirelessly. My first attempt was unsuccessfull. today I'll try to change configuration.

I just read, that if you have a lot of wifi devices in your house, or in the surrounding area (and you may not be aware of how many 2.4Ghz devices are in the neighborhood), if you change your router setting to 802.11n only (5Ghz) that will aleviate any dropping. But then you might need an Airport Express to print, if you have a wireles printer, and the Airport Express acts sort of like a bridge, turning your wireless printer to a wired printer. Try changing the setting on your router so it reads 802.11n only (5Ghz).

I've been an Apple customer (three desktops, two laptops, an iPad and three or four iPods) since the mid 1990s and nothing has shaken my brand loyalty like this wifi issue with Lion.

It was annoying enough when the upgrade to Lion (on a 27" iMac that was one month old at the time) introduced the wifi-dropout problem every time my machine woke. But then the usual fix of unplugging/plugging back in my Airport Extreme stopped working completely yesterday ...

It is absurd that this documented problem with Lion has persisted for so long. Over that period, I've wasted hours with reading about and then implementing various tricks to fix the problem. Nothing has been a long-term solution to this long-term inconveneniece-turned-nuissance-turned ceaseless frustration.

Shame on you, Apple. Don't you dare presume that I'll just buy your next device out of habit.

So reset your router... obvioulsy you have messed it up. Just because you loose conection, you dont fix it by unplugging it and plugging it back in, your going to cause a short, or worse mess it up. Shame on you! No wonder why your wifi does not work!

... except that it would fix it (temporarily), and it fixed the problem quicker and more reliably than any other so-called solutions.

At times, I also reset the router.

At other times, I followed the latest solutions that were posted here, on macrumors, or other websites.

I was bummed to discover that this solution didn't work for more than two days, despite its claims.

Here's an interesting scenario I have. I have Lion on one partition and Win 7 Home Premium on the other of my iMac 27". When on the Lion side I have the intermittent wifi drop outs or it shows as being connected but email and internet stops working. I have to disable wifi and reenable it and it works for a while until the problem repeats. I can boot over into the Win 7 side and I have yet to ever lose connection.

guyfromanytown,

I just did the same thing and Windows 7 on my macbook works with my airport card, NO PROBLEMO!!!

I would hope this helps solve that is a software/driver issue with lion.

Tony, that's why I chuckle at some of the naysayers that claim it's an interference problem, a router problem, a signal strength problem or the moon being in the incorrect phase for premium wifi. I'm convinced it's a Lion driver issue.

If the router is defective, replace it. (chances are your router is fine, and the settings have just been changed either by accident or by deleberate action) And if need be reinstall Lion (Apple has made it wicked easy to reinstall Lion). If your router is starting to fail, this would explain why your router needs to be unpluged and plugged in, and I would bring your router into an Apple Store. It is a piece of eletronic equipment; all it takes is some humity or moisture or dust or extreme temperature range or some sort of fall or some sort of surge and it becomes junk). If your not sure if it the router, here is a way to test the router out, Unplug the modem, and the router. plug the modem in, wait fifteen seconds, then plug the router in, once the router is pluged in hold a pen to it at the reset button in the back of it till the amber light blinks rapidly. Do this only once. (dont unplug and plug in your router repeadely - that will only hurt it- and is your first clue that this might possibly be the router.) ok once the amber light blinks rapidly release the pen. Then open your system preferences, click the network tab (button, icon, what ever you want to call it.) Put a check mark in the box that says "Show Wi-fi status in menu bar." Next go to the left column and select your Wi-fi by clicking it. Then hit the minus sign to remove it from that list. Next go to the top of the window and change your location to Automatic, if it is not already selected. Next select the button on the bottom that says Assist Me. Your going to get a screen that says Assistant or Diagnostic. Click Assistant.  In the next screen it asks you if you want to name your location.... you can either leave it alone or change it to Home internet. Choose either I use a cable modem to conect to the internet or choose I use a DSL modem to connect to the internet. The next screen, just hit ok, then the next screen hit done. Close the system preferences window. On the menu to the left of the time at the top of the screen you will see an icon that looks like a tornado choose the network that says Apple.... That would be the router. Now that you are on that network, open up the application Airport Utility. Proceed through the set up. On the first screen, select the option that you want to restore this TimeCapsule/ Airport Extreme (TC/ AE) to its factory settings and then set it up again. Next screen, give the TC/ AE a name and a password, Next screen, use the devices current settings, Next screen, create a network, Next screen change the network name from Apple.... to what ever name you want and create a password, Next screen, connect using Ethernet, Using DHCP. If you are on DSL... this option (not totally positie) might be PPPoE but I am not positive with DSL modem. I have cable so i am looking at my settings. Next click Finish. Leave it for a few seconds to see if the green light become active. If your able to conect to the internet fine, then your problem is solved, if not, see my message above. If you are still not sure visit an apple store, with your router and computer. Make an appointment first. You could also call your Internet provider, and they can reset your modem from their end.

I actually downgraded the driver to snow leopard driver (atheros 3.2) as documented in other places, and it worked for about 6 hours no issues. But the problems slowly crept back in. After a day I was back to every 5 minutes loosing connection. I now have a solid connection after upgrading my router to a Netgear n600, my Imac is isolated on a 5gz channel all by it's lonesome and that seems to work. (at least for me)

Yeah I scratch my head when ever someone says buy a new router and what not, when WIFI standards are implemented in all routers. When I hook up my little USB WIFI dongle(no pun) I have yet to lose connection on any of the 8 networks I connect to on a daily/weekly basis. I'll continue to use the USB WIFI until a fix is out. Windows 7 isn't so bad, all i am gonna need to use it for is for Office programs.

networking is about getting numbers to match numbers. If the settings on your computer dont match the settings on the router exactly you will have trouble. it has nothing to do with a driver problem unless it is a driver problem on the side of the router. 

I didn't actually by the router for this issue, I had resolved this issue with with a Netgear Universal adaper which cost me 26.00. I ended replacing the router because I had known issue with the router keeping a connection itself. The issues were totally seperate, the router would drop connection maybe 3x a week (at horrible times). I have 6 other systems in the house and it was just time for an upgrade. It just so happen when i change the router, something said test the Imac on the 5gz channel and it of course it worked and has been working every since.
