The only thing that is making me feel better about this issue is that I am not the only one experiencing it. Not that anyone should, but everything that I have been reading here echoes my experience. Before the 10.7.3 update, I tried all the suggested fixes, and none of them worked. Then the update comes along and it IS SUPPOSED TO FIX THIS BUG, and IT DIDN'T! Just to review, I did the following:
Reset the PRAM
Reset the S-DRAM
Reset my router
Reset my modem
Changed some network settings
Created a new location
Updated the software
Repeated a few of these steps several times
NOTHING! I love my iMac, and switched to Apple over a year ago, but I have to say, when Apple software messes up, it really messes up. Hang in there everyone.

I have to say, I am pretty steamed about this. If, as CocoRallado states, an external USB wifi adapter solves the problem, then this is something that Apple should pay for.
Everyone who has AppleCare: call Apple and complain. I plan to do so very loudly tomorrow morning. If they won't fix it, I will forward this email chain to one of those class action attorneys. We will all get external USB wifi adapters for free -- in about three years when it will no longer help us. At least the attorneys will get rich though.
I have had Apple products since 1989. This new iMac is the first one that I've had problems with (including a Moto StarMax!).
This is the easiest and most effective way to fix the problem with Wi-Fi dropping with OS Lion ( mostly ) but with OS Leopard as well. I have tried many solutions posted on this site and also on the Goole, but have all failed.
I decided to buy an external USB Wi-Fi adapter that is Mac compatible, and guess what. Problem solve! I have actually bought two different types of USB wi-fi adapters and the only difference was the size. The first one is made by Iogear GWU625 which is a liite fatter than the othe one made by Zyxel NWD2205. Both of this devices work fine, just have to search for the drivers as the mini cd included is useless on Mac and does not provide you with the right softare. I found out that the Xyxel usb wi-fi adapter is smaller allowing you to use a mouse on a MacBook Pro which ony has two USB ports, and for me makes it easier to use than the standandard mouse pad, the othe wi-fi adapter is a little fatter and won't allow you to use the other USB port unless you use and extension. Both devices work fine, no wi-fi dropping and all this for less than $ 30.00 dollars a piece which is worth. No more headaches or rebooing to get back on the web.

Installed 10.7.3 in hopes it would fix these wireless problems, but tonight, my wireless connection is acting up on my MacBook Pro 13-inch, Mid 2009.
Let me explain a few weird facts to see if it helps any of us figure out what is going on.
I had NO problems on this machine UNTIL a few days ago, when I installed a brand new SSD and did a new install of Lion. Keep in mind, I was running Lion before, on a system that was upgraded from 10.6.x.
My problem is that all traffic stops dead for 5-25 seconds. The wireless stays associated, but all traffic stops. I have a constant ping going to my Apple Airport Extreme, (ping 10.0.1.1). When the problem occurs, if I switch to my command line window, I see that all pings fail during the glitch, then come back after.
NOTHING shows up in the console during the time when the problem occurs.
I've been experimenting with the built in "Wi-Fi Diagnostics" tool in Lion, but it also doesn't seem to pick up any of the problems either.
My best guess, and it is ONLY a guess, is that this is a very low level kernel driver issue with Lion...

Hello everyone, I keep reading that you still have problems with wifi, has anyone tried to fix the settings of the access point?
Try to set a channel of communication, possibly not in use by the AP, you can control the channels used with this free application iStumbler, then set the frequency on 20Mhz with a speed of 108Mbps.
I upgraded to 10.7.3 and have found that with the precautions taken and the PROBLEM SOLVED.
If you have problems write the model of the AP and try to help. Sorry for my English. : D: P

10.7.3 does NOT fix this problem. I had an Apple update today (Feb 3, 2011) but my Macbook Pro still cannot maintain a WiFi connection. I have 3 different WiFi bases set up about 4 feet from my Mac. NON can sustain a connection! Thisi is unacceptable!
Every othe device I have that is non Lion, (iPad, iPhone, Windows 7 or XP) have no problems with the same bases stations.

I think exactly like you, but at the moment if the resolution of the issue is under review by the Apple and the temporary way is to set the AP is compatible with Wifi.
Where do you live?
I'm in Italy.

I am in Australia. I have AP from Netgear Cable modem, Netgear UTM9S with WiFi plus a Fritz Box.
I need to have my Apple laptops work in different locations, such as customer sites, so playing with the AP is not an option.
This is very frustrating.

I have a late 2009 iMac which was running Snow Leopard. The issue is the wifi card and the upgraded software that Lion installs. See the link below. It completely solved my wifi speed and connection issue.

Bewarned. Loading an older driver from Snow Leopard on top of Lion can cause upgrading issues for future software releases. Some users are experiencing this firsthand using the driver install package mentioned above.
Use at your own risk...

Hi, yes your poss right, however for the time being I have the interweb which is important for me. If future updates cause me issues then I can carry out a re-install..
Maybe not the most ideal situation I agree.

No problems until upgrading from 10.7.2 to 10.7.3 yesterday. Now wi fi doesn't connect after wake up. Have to execute wi fi off then wi fi on to fix. AppleCare is pretending that I'm the only one with this bug. Let's all of us BUG them until they acknowledge/fix this. Their response is so far very un-apple like!

82 pages of complaints about this issue should tell Apple that this problem needs to be resolved. It bothers me too when you contact AppleCare and they give this impression that they aren't aware of the problem. Well, the latest update specifically acknowledges it, claims to fix it, and then does not. Not sure what else to do at this point, because I do not feel that, as some of the earlier posts suggest, one should have to buy an adapter or some other auxillary product because there is a bug in the software. That is not right. So, I guess everyone needs to continue to voice their disappointment until it is resolved.

Thanks for bringing this topic ..I have exact same problem with WiFi when my router is just 2 feet away. Reported to Apple Care and bugreport team but no solution. In fact i used LAN connection and turned off wifi but even lan connections drops off while rest of my devices working fine.
I think if Apple asks us to provide logs on basic functionality is preety DUMB by them. They introduced this bug in Lion and seems to be in denial of accepting it.
Another frustrated user

As previously mentioned, if you have a late 2009 iMac you'll poss have issues. Go to the link below and read it. I followed the instruction, understood and downloaded the patch and solved the issue. I now have wifi....
