Mac OS X lion 10.7.3 Wi-Fi connection Drop Issue

Question

Hi All,
  I've iMAC OS X Lion 10.7.3 latest version desktop. For couple of months, I'm dealing with dropping wi-fi connection during working. I've look at all the forums and discussions and tried many things to solve the issuse, however, issue still exist.
   Every a few minutes, even during surfing though internet pages, wi-fi connection drops. When you look at the signal level etc.. everything is seems to be fine, but it is not possible to connect internet after close-open wi-fi.
   For a while, connection drop happens again.
   I do not understand why Apple does not give a fix for this while most the customer having such an issue.
  Any one having any idea how to solve this ?
Regards
Gokcer

I have a similar problem.  My Macbook Pro won't keep a constant wi-fi connection, becuase it continues to seek alternative networks even after locking onto a strong signal.  I've reset preferences and started from scratch with all the settings and let the Mac set them by itself, but still it does the seeking.  At home I used to have a direct LAN into my Airport Extreme, but now I use wi-fi on 4G/LTE and I've tried the computer with and without the Airport Extreme, with and without a Cradlepoint, and with various channels and security levels. 
As has been document probably hundreds of times in these forums, Macbook Pros (my model) and some other Macs have had this issue from either 10.7.2 or 10.7.3 (I've got 10.7.4 right now).  I'm glad you found a solution to your problem, but for the hundreds or thousands of us who've had this problem since last August with no solution from Apple, it's quite frustrating.  I know it's not politically correct to blame the computer when it's been given a defective upgrade with Lion, but let's call it what it is.  I'll side with the numbers.  Either a sudden batch of defective routers showed up from Taiwan, and a group of late 2008 and 2009 Macbook Pros bought them all en masse, or it's the software. 
So if you still have problems after you get a clear signal, start sending messages to Apple to get it fixed for all of us.  I bring this up for you as an alternative, as I noticed you were running 10.7.3, and the problems started somewhere around 10.7.2 or 10.7.3.  Something to keep an eye on.
