Constant popup "join Wifi-network"

I suddenly am interrupted every five minutes by a popup that says on the window frame "join (name of wifi network here)".


In the window is the message


"<HTML><HEAD><TITLE>Success</TITLE></HEAD><BODY>Success</BODY></HTML>"


What is wrong with my wifi network that I get this?


How can I make it go away?


Thanks!

MacBook Pro with Retina display, OS X Mavericks (10.9.4), 512 Gb SSD, 16 Gb RAM,

In the bottom of the frame I can see this: apple.com/library/test/success.html

Same thing. All sorts of weird wifi issues actually for last couple days, but not sure if they were coincidental with odd issues with my ISP too. But as for this wifi network popup thing, it definitely appears like one of these security or EFI updates has made things screwy for us 10.9.5 users. Hopefully Apple already knows and is working on a fix. 😠😟 I wonder if they released these updates knowing this would happen....

HI All,

Apple uses a method of pinging back a 'hidden' web page when ever you attempt to use wifi. This is used to check for login screens on wifi portals, but it appears to be broken at the moment.


The server is passing back badly formatted HTML that is then displayed on the screen modally (in front of everything and in focus) which interrupts what ever you are doing if connected to wifi.


At the moment the ONLY work around appears to be not to use wifi (this is obviously unacceptable)

Same problem here on a Macbook Pro running Mavericks 10.9.5 connected to Apple Airport WiFi on 5Gz channel. Odd is however that we have two MacBooks running the same OS version, connected to the same router. One is getting the screen every five minutes and the other is not.

However if I try to check the network prefs on the machine that doesn't have the problem, it has difficulty loading the tabs (TCP, DNS etc.) on the "advanced" dialogue.

I have tried restarting the computer, router and the wireless network hub. Still got the pop up. It is affecting my iMac (10.9.5) but not my iPhone 5s (8.3) or my iPad mini (8.3). I also see it isn't local to Apple products, Android seem to be having problems too.


Not that it has solved anything, but I have simply put the offending window into the corner out of the way, the computer seems to be working fine, internet works, email works and so on. Running a virus scan now, but I don't think it will be that.


My guess as some hacker has done something to the web. But then what do I know?

Go into [Hard Drive] -> System -> Library -> CoreServices


Find "Captive Network Assistant" and rename it to "XCaptive Network Assistant".


Voila! No longer a problem.


This is at least a temporary fix to resolve the issue until Apple fixes the problem at their end (who knows how long that is going to take).


In terms of overall impact, it will only affect people on corporate networks or airports that need to input corporate usernames/passwords. If you're just connecting to your wireless at home it won't have any impact.


This is one of the reasons I suggest also not "deleting" the file and instead "renaming" it to get it out of the way, temporarily whilst Apple fix the issue so you can then rename it again after they fix what they need to.


At least it won't get in your way every five minutes whilst trying to surf the net.


Anyway, hopefully that helps everyone.


Regards,
