I had to revert too.
Wireless worked after install, used it to update all my probrams in the mac store. even installed Abobe and all of its updates. shut down for the night,then no wireless at all.
I click on the "turn on wireless" nothing.
Went to the apple store and became their gunipig for 3 hours, finally they decided what i needed was a fresh install. Which they did, i got home all was good of hours. Again installed all my stuff and shut down for the night.
next morning no wireless again. This stinks. I am new to apple and feel like this is just typical of a Windows problem.
For all who have problems: it would be interresting to see if the problem persists when you change to another wifi network. For myself: I experience problems on one of my home networks (i have two), the one that has a Airport Express connected to it. On my other network with Cisco gear and at my office network with Juniper gear I have no problems whatsoever.
It might help Apple to troubleshoot (I'm sure they are reading this thread) if you can answer these two questions:
- when experiencing problems, what make/model of wifi router are you connected to?
- if you switch to other wifi networks with another make/model wifi router/access-point (please also specify), does the problem persists?
I want a refund.
I have a 27" imac under SL I had no wi-fi issues, under Lion, at first drop outs every 5 or 10 minutes, I tired numerous solutions offered and no result now I am flat out keep a connection open for 30 seconds.
Wi-Fi is an essential part of an OS these days. No internet on my imac it may as well be a shinny paperweight.
I was a convert and said I would never go back to Windows but no wifi is inexcusable it up such an important aspect of an OS they call this an upgrade. I thought apple was not following windows in more glitz more glamour less stable with every new OS, to release this product without adequate just shows apple is going the way of windows.
I will be demanding a disk for the OS patch to fix this because there is no way I could download on my wi-fi connection.
Keep posting if you have this problem.

Your want a refund and demand a disc to update because you won't be able to... Even though your able to use another computer? :)
I think everyone who isn't happy should downgrade to sl till 10.7.1 comes out which will b soon.. Or deal with not being able to use facey for a few days. Sheesh. Smell the roses everyone.
And before I get messages back about its affecting business etc. It affects me too. But be proactive about it and either downgrade. Or wait. :)
Just to get to the bottom of this, I set up Wireshark to monitor what was happening on my wifi connection. While not a pro at this, the messages clearly indicate something odd about the DHCP handshaking right at the start of the connection protocols. I sent the Wireshark file to AE via bugreporter. Then to amuse myself I used Time Machine to go back to an earlier build before DP4 where I don't remember having problems. Sure enough 11A419 (DP2 perhaps) has absolutely no problems on the same machine that the DP4 and GM builds cannot hold a wifi connection on. Not only is it the same MacBook 4,1, but it also has the same software installed exactly excluding the OS. So what does it prove? DP2 works and GM doesn't. Something Apple coders did between the two has caused this problem for some of us. I am typing this mesage from this machine and the wifi has been fst and solid for 30 minutes.
Now I think it is a case of letting Apple find the damned bug in the code and issuing a patch.
Yes - a very frustrating wifi problem. Bought our first Apple product for the wife - the new Macbook Air 3 days ago. Our first experience was owning an Ipad (we won it in lucky draw..) which convinves us to try the macbook. After the long wait for a refreshed MBA - very deflated with the wi fi problem.
A mistake perhaps to have not purchased a normal laptop instead. Wifi keep disconnecting every few minutes - it worked fine with my other Window based laptop and Ipad. Have spend a few hours browsing internet for solution and called the Apple support. No joy yet.
Especially frustrating that there seems to be no official fix - only the routine 'go through all the steps' with the apple helpdesk which is obviously not working.
Does apple refund policy cover the above? my wife certainly wants to return the MBA (i am using my window based work laptop at home). A non working wi fi sounds like a pretty defective product to me.......
Back on my Mac, disabling wireless N network as suggested on my router was not a good idea, connection kept falling over every 5 seconds. Enbabled wirless N again and my connection is more stable in that it falls over every couple minutes but still falls which it never did under SL.
Whilst I doubt I will never get the upgrade on a disc but I would hate to rely upon my net connection for the upgrade.
Apple are you going to aknowledge the problem.
One plus with Wifi Problems :-( . I'm buyed a iMac 27" this past saturday. With Snow Leopard all works like a charm, with lion... the Mac seems to be "charmed"....
Now I'm at work, but many people seems to report some problems with DHCP, at home, i have DHCP but with Mac Fixed Address. May be this configuration part of the problem? I'm try to test the same without that. By otherwise, i hope that apple publish a patch for this problem. May be 10.7.2?

After a whole day dailing with the problem, now I can say that I have finally fixed the problem, how?
As sugested in one of the first posts, I turned on my iMac in Safe Mode (turning on the computer with the Shift key pressed until you see the wheel, this suposedly clean thingd on your computer, why not, it makes sense and it should be true. Then I restarted again the computer but the problem was still there. Then I did a couple of things, first I moved the wifi to the top of the services, and removed all the networks that I have been connected in the past leaving only my home wifi. When I restarted the computer, my iMac finally started with the wi-fi working.
I hope this helps,
The July 24 post from julianfromardmore describes the process that an Apple Support tech went through with me and it did the trick!!
Like many who have posted here, my problems began after an install of Lion. This fix was just applied and tested so I haven't had much experience yet to say if it will last but it sounds like it will. I will repost the bad news if it comes around to that.
One other thing: in my case, I was using a private network from an Airport Extreme base station as of the time I installed Lion. I can't help but wonder if that was part of the problem. However, since so many seem to have had this issue after installing Lion, I am thinking the private network status was not part of the problem; just something that was fouled up in connection with the Lion install.
Ok - scratch that.
After returning to my Mac just a little later, the same problem reappeared. The Wi-Fi connnectin IS fine but for some reason my computer just doesn't make the connection after it has been in sleep mode for some time. If I manually rejoin my network, the connection works & is steady. But the computer just won't find the Wi-Fi initially.
