    The wi-fi issue isn't the same for everyone, so one fix for someone may not be the same fix for everyone else.  The wi-fi dongle is like an external wireless card that plugs into your USB drive.  Just like an external hard drive that plugs in to your USB.  I recently spent $50 on one of these USB wi-fi dongles, and I still have the same network drops as before. 

    But I've heard stories about a dongle resolving other people's issues.  Trial and error I guess.  It didn't work for me, so I'm going to return it and keep investigating.

    This is the key point in this list.   Some people seem to have "The Apple WiFi problem".  But, so many others do not.  They have some other problem with their network, but, because it involves WiFi, and they've found these threads, they just believe that there is only one problem.

     

    What is important to understand, is that Apple's WiFi appears to be counting on utilizing every bit of the features of 802.11g/n as best they can.  There are apparently some routers which are incompatible with this expectation, or Apple deals with their 'non-support' in unexpected failure.  But at any rate, everyone needs to make sure that their routers have the latest firmware from the manufacturers' website.  These devices are almost always shipped months and months before they appear on the store shelves, and then months can elapse before you buy them, and all that time, new devices are getting software fixes which you need to download and apply.

     

    Without doing that, your expectations may not be met.  If you don't have the technical skills to check the firmware on your router, then hire someone to do it, or buy/rent a router from your ISP and get them to manage it for you.

    Wifi symbol is black, so apparently it's "on", but pages won't load, videos freeze in youtube, etc.  Then I do get the "you are not connected to the internet" message.  The only solution is to manually click to turn wifi off, then turn wifi on.... wait..... then select our network from the list.  Sometimes this doesn't even work, and I have to do a restart.  This is ridiculous!!

    I have no computer technical smarts what-so-ever, but it doesn't take a rocket scientist to figure out it is a Lion issue!  My old dinosaur PC worked on our old router without dropping, and all our other devices never, ever, ever drop.  Only the Mac.  Hmmmm.....

    If the bars are black, than your WiFi is working fine.  What is not working, is something between your computer and your ISP.  If you have someone with technical skills around you, who can help trouble shoot this, at your house, that would be the best bet.  Look on the comments here about "ping" and using that with the IP address 8.8.8.8 (the public google DNS server).   If you can get "ping -n 8.8.8.8" to work when your "WiFi is not working", then you have a DNS problem.  You need to check with your ISP about that, and also look in the networking system preferences.  Select WiFi Adapater, then click the Advanced button.  On the DNS tab, there should be NOTHING there when your WiFi is disconnected.  When it is connected, your ISP should provide working DNS servers whose IP addresses will appear in that list.  You can try adding 8.8.8.8 to that list, and move it to the "top" of the list to see if that changes your situation for the better.  If it doesn't help, then delete it from that list.

     

    There are lots of people who have had this kind of behavior, and many of them fixed it by doing something with their equipment or ISP, because that path to the internet had a problem.

    I have a new mac mini with mountain lion and because I have several Macs, did not really pay attention to the wifi issue until I was spending more time using the mini. The wifi connection was constantly dropping. I have a cable modem router as well as a Cisco aironet access point. All of my Macs are connected to the Cisco access point but only the mini has mountain lion. After switching the mini to the ssid on the cable modem router, I have not experience the disconnection issues. I have not had time to look at the aironet access point settings but one size does not fit all in this case.

    Yep, I wish the original issue was clearly defined as "WIFI system crashing" not "WIFI dropout".

     

    The original problem is a genuine bug, starting with Lion that wasn't fixed, in my incarnation of it, until Mountain Lion.

    Where the WIFI system crashes entirely - everything to do with WIFI dies. No network, no AppleTV, no internet... nothing.

     

    Anyone with "connection dropout" issues where a connection is "constantly dropping" have some other trifling issue.

    Hi momof3bnd I had the problem for a year, but as far as I'm concerned, it was fixed in Mountain Lion. Have you tried it yet?

    Hi furrytoes - Nope, haven't tried Mountain Lion yet. 

    Gonna try the various suggestions above, like what gphonei wrote above, and see if my husband can help me figure this out.  Might take a few days - will let you all know what happens.  Fingers crossed!  Thanks to all!

    Mountain Lion is cool and all...but don't spend the money just because you think it will fix your WiFi issue.  I upgraded to Mountain Lion, and STILL have the same WiFi issues as before.   It's not a hardware issue because I bypassed my internal wireless card by installing a USB dongle, and still had the issue with the dongle.  I spoke with the dongle manufacturer about it since all they deal with is WiFi, and they suggested that it could be a router issue or ISP related.   Funny thing is, right next to my iMac is an HP laptop connected to the same wifi connection, and it doesn't have the drop outs.   So it has something to do with OS X....just not sure WHAT part of OS X yet.

    Do you have the most recent firmware installed in the Cisco router?  This seems like an issue with the functions in the router since you could switch AP wireless endpoints and see the behavior improve.  A lot of people seem to report that upgrading firmware was a solution for them.   What security mode does each of your APs use?  Is there a difference in supported modes, b/g/n and what you use?

    What indication of "WiFi issues" do you get?  Are you just getting a message in your web browser that says "You are not connected to the Internet", or what?  When the disconnected state is occuring, do you see "black bars" on your Airport indicator on the top right side of your screen, or do you see "gray bars" which indicate the WiFi connection is not up?

     

    If you see black bars, then you are experiencing something at the higher levels of networking.  If you open System Preferences->Networking, and then select you wireless adapter, and select "Advanced" and then go to the "DNS" tab, when you are connected or disconnected, do you see different DNS servers listed?  If the list is not "empty" when you are disconnected, then you probably need to remove the rogue entries in that list.

    To update my issues, things were running ok for the last couple of months and the issue started to return.  I just ended up hardwiring and giving up.

     

    To answer the quesion phonei has been asking, when I have/had drops the WiFi indictor would always switch from black to grey.  When drops happen every 2 minutes, which can happen, it turns grey every time.

     

    I have managed to get it working for fairly long periods of time running through fixes in this thread.   The problem is it will just randomly return.

     

    Mentioned before, but it's a late model 2011 iMac running 10.7.5 at this point.  Problems started when I first updated to Lion from Snow Leopard.

    This kind of random behavior, is often attributable to interference coming from another device.  Are you using 2.4ghz?  If so, a baby monitor, or wireless phone, or VCR Rabbit type device.  I bought one of the X10.com advertised wireless video sender/receiver pairs, and it just killed my 2.4ghz network in the house.  If it's random, then perhaps a neighbor is turning something like this on, and it's affecting your wireless signal.  If you are on 2.4ghz, what channel are you using?  Did you try 1, 6 and 11 each in turn for a long enough period of time to note whether one channel was more likely to fail?  Also, if you can find some wireless network analysis tools (mountain lion has some in it), that might let you see whether or not there is enough other WiFi traffic, that it's just so many people around you that the signals are being interferred with.

    The problem is there are no new devices in the house, no new wireless networks in the area, and nothing else that has changed in the time I have had these problems.  I have switched channels, and that was one of the fixes that helped for short time periods.  Eventually, the issue would return though.

     

    I have been with this thread since the early days, so trust me channel switching was one of the first things I tried. I also tried an Aiport Extreme during all of this to test what would happen, and it had the same issues eventually as well.  

     

    During this time there has not been a single other issue with any wirless devices in the house.  There are phones, laptops, tablets that use the network with no issue.

    You might have missed my earlier report, but I'll summarize it here.

    My MacPro and Macbook would lose Internet connection 1-2 time each day ("... You are not connected to the Internet..."). The MacBook uses WiFi to my Cisco router, but the MacPro is Ethernet hardwired to the router. Made no difference ,,, both would lose connectivity. And like you, my Windows machine as well as FOSCAM cameras, 2 iPhones, an iPad, a Roku, Apple TV, a BlueRay player ... all were OK.

    Well the problem got fixed 2 months ago, although by accident. My cable MODEM was behaving poorly and Brighthouse exchanged it out for a newer model. My Internet access speed went up by 5X to where it should have been.

    I haven’t had the problem since. So why does changing the MODEM fix the problem?

    It is some form of timeout action. It may be those apps which periodically communicates over the Internet to gather data; mail queries are a good example. I suspect that if the Internet connection is even slightly degraded and these apps get “upset” waiting for a reply, they notify some extension of the OSX that, in turn, pulls the Internet plug.

    You might do some diagnostics on your throughput with your ISP or try logging on via another WiFi network where people are not experiencing these drop-outs.

    Regards

    Okay, I'm not asking if you did your homework or anything like that.  I'm just trying to figure out which things you have tried and what the results were.  It still sounds to me like somewhere around you there is a 2.4ghz interferring signal.  When you tried the Airport Extreme, did you try 5ghz?  If you did check with 5ghz what was the results of that?
