Lion 10.7.1:


When my MBP boots or wakes up, if its in range of a wireless network, I'll get a pop up browser window asking if I want to join it - even if my browser's not running. Being a pop-up, this isn't a full browser window and so doesn't contain my 1Password extension button, so its pretty annoying.


Is there a way to turn this pop-up window off?

    Has nothing to do with your browser. It's just looking for your network. System Preferences>Network>Advanced>WiFi. Make sure you have the box checked, "Remember networks this computer has joined' and your network's name is at the top of the box.

    Can you post a picture of it?

    it should look something likethis if it's trying to connect to WiFi:


    If you aren't running a browser, there's no way that's a browser window. If it is, then simply go up to the menu bar and under the View Menu choose "Show Toolbar" Check the url to make sure it is a legitimate site you know.


    Once you can see the toolbar, you'll be able to access your 1Password button. You can also open 1Password, filter the listings for your router name, and copy the password to paste into the window. However, if it is a web page, you shouldn't be giving anyone your passwords to your computer or wifi network.

    Okay, assuming it is a safari popup that comes up when you join certain networks, then you should be able to make a screen shot: command-shift-4 by default. Check your system preferences>keyboard>keyboard shortcuts for exact key stroke. If not, if you can take a picture of the monitor it would help.

    To my knowledge there is no mechanism in lion or any other OS X release that uses safari to log in to a wifi network.

    there are third party products that might use safari, but it strikes me as odd, and suspicious. I don't want to cry "virus" or "phishing attempt" yet, but that's my gut reaction.

    Thanks again Michael, but no, it's not a phfishing attempt because its not from one site or even one network or one router. It happens everywhere, all over town.

    I will capture it, but really there's nothing to capture — it's just a safari window without the toolbars.


    However, I think you have hit the nail on the head with this:

    That seems to be exactly what it is.


    I know exactly what you're talking about. You don't use the browser to connect to the wifi network but you use it to authenticate. You see these commonly on public wi-fi services such as at airports or hotels.

    Ah! I just got that window for the first time at a starbucks. I decided to try to find out where it came from. It's not safari, nor the finder. Luckily Little Snitch clued me in: It is most likely the Captive Network Assistant App located in


    So, let's go on a google hunt...

    ah ha! (scroll down a bit) So, that establishes that yes this is the gremlin in question.


    And in our own discussion forums (thank google!) we find the answer: (The last answer tells you to go into activity monitor, find the CNA process and unmercilessly kill it...) Ya! I just hope Safari will step in and allow you access to that same window. That and I hope Apple fixes that bug/halfbaked app with an update to lion.

    I'm kind of tired right now (it's about 2:30AM), but from ewhat I recall (and I haven't had to recall this info for a long time) there's a file accessed in the boot process (like all Unix systems) that tell the system which apps to launch. I'm not sure if the Captive Network Assistant is fired off on boot or not, but if it is I'd would be in there. I remeber that in the /Library/ there is a Startup items folder which has apps fired off from it


    search time!

    I found this. It's all in one place now -- wish I had that years ago! --


    But I looked around and that was fruitless. So, I suggest the following: navigate to the Captive Network Assistant app, move it to someplace safe (in case this breaks your ability to connect), Zip it up to make a copy of the app the OS can't get to directly, then toss the app in the trash and erase it.


    Then head to a local starbucks (or any wifi network that requires you to log in or agree to a TOS) and see if (a) captive netowrk assistant pops up (whichit shouldn't) and that (b) you can connect the old fashioned way: by trying to navigate to or or some other reliable site, and then getting the login/tos acceptance screen in Safari where you cna access 1Password.


    If you suddenly find that you can't connect and no screen comes up in Safari, unzip the CNA and put it back where you found it. Then let me know and I'll look for other work-arounds. (I really hope Apple implements a full Webkit stack that is extensible to 1Password and other password managers -- either that or "rolls" CNA into Safari as a float-over page that can still be seen by 1Password.)

    Thank You, Thank You, Thank You


    I was starting to loose the will to carry on.  It works so well on iOS but not in lion.   I deleted CNA and now I'm able to logon to my networks first time, everytime - No hangs any more.


    I like lion but it still has these niggles.  Come on apple and sort it out!!!
