This network is misconfigured. When connecting to the internet using wifi! Seems to be happening across the board with a lot of people out there??

hi guys,

Since Monday/Tuesday of this week, people using our 'Wifi' are literally getting a 'This network is misconfigured' page with a
<!-SPLASH_GRANT_URL_START->Click here to continue<!-SPLASH_GRANT_URL_END->

If we click on 'click here to continue', it goes to the normal webpage. However, we have had complaints from sites remote to us who just use ADSL and not our DNS etc. I've also seen people on the internet complaining about this?

Any ideas?

Thanks
Yashy

Sounds like a DNS problem. Can you be bit more specific about your problem and your layout. It is hard to diagnose with the meagre information you have given us.
Jan SpringerCommented:
If you're using a hotspot environment, also include that information.

Hey guys,

Apologies for not responding sooner. I should have been much more thorough. Reading it again, I wrote it up for you very poorly.

Here is an attachment of what we see when we surf the web when connected to our wifi.

Any ideas what it could be?

Cheers
Yash

what operating system is the auth web server running?  and what app software is doing auth?
YashyAuthor Commented:
We're not running a web server. I'm staring to wonder if there is a compromise on our network?

We have Cisco access points. These access points are connected to a switch which are then connected to our ADSL internet lines. We merely authorise by accessing the wi-fi SID and enter the password and we surf. However this is now coming up for everyone who tries to connect to the internet via our wifi.

Can you access the management interface of any AP?

Is there any log data?

Have you rebooted a single AP to see if it resolves the issue?

Are there any licensing issues to take into consideration?

Are these Merakis?

In the end, I found that somebody had plugged a Meraki into the network! The license had run out and it was causing an entire network problem. Sorry for not responding earlier, it literally took a while to figure out what was going on. Thanks for helping out.
