“incorrect password” error on iOS devices on UniFi wifi network

Source: https://gonza.fi/en/unifi-incorrect-password-ios-iphone-ipad

The Unifi line of WiFi access points from Ubiquiti have a strong reputation for being reliable devices. However, many users are reporting “incorrect password” errors when using premium mobile devices from Apple. Fixing this issue is easy using the Unifi controller WiFi settings.

The reason for the error is WiFi management done on iOS devices. The default settings for the Unifi range are not compatible with iOS 11 and 12. The reason for the error is the “DTIM Mode” that has to do with the beacon timing setting due to power saving. The default value for the Unifi WiFi devices is 1, but it is recommended that this be set to 3 or higher by Apple.

The remedy is to done using your Unifi Controller. Open the administration interface, go to setting and select WiFi. Then select the WiFi where iOS devices are experiencing the “incorrect password” error. In this section you can apply the configuration steps with the following steps:

– Open 802.11 Rate and Beacon Controls
– Uncheck DTIM Mode checkbox for Use default values
– Set DTIM Timing to 3 for both 2G and 5G

That is it. This configuration works better with the power saving features of iPhone and iPad devices on a WiFi network powered by Ubiquiti Unifi wireless Access Points.

I am using a 1st generation Ubiquiti Cloud Key to manage the network so:

  1. Settings > WiFi > WiFi Networks
  2. Mouseover the network name and click on Edit on the right side
  3. Go to: 802.11 RATE AND BEACON CONTROLS
  4. Toggle on: Override DTIM Period
  5. Set both 2G and 5G DTIM Timing to 3

4/20 daily COVID19 reading log

I think it’s interesting to see the narrative changing now that we are progressively peaking in various states. It will also be interesting to follow the epidemiology as states reopen in staggered and varied fashion. In the absence of any significant widespread PCR testing or antibody serology testing, it is still throwing darts.

Change is hard, but also good

Some personal news:

I am joining @cityofhope as #CMIO starting today.

Words can’t really describe how will greatly I will miss my @HarborUCLA and @Harborpeds family (but I’ve never been short of them, so I’ll try). Harbor-UCLA Medical Center (nee Harbor General Hospital) has been my professional home for over 25 years and is where I trained to be a #pediatrician, met my wife, became a #clinical informaticist, grew a #PHM program, implemented @Cerner #EHR, and had the wonderful opportunity to work with and learn from hundreds of residents and fellows. Thank you to all of my faculty colleagues for making it a place that I love. Thank you to #CMO @anishpmahajan #CEO Kim McKenzie #PedsChair Lynne Smith for providing me with the opportunity to do what I live to do. Thank you to the #CIOs (Mary Morgan, Sandy Mungovan, Katie Uyemura) and their awesomely talented IT teams for allowing me to incessantly ask/bother them in my quest to improve the #HealthIT user experience. Thank you to all of the amazingly! talented! pediatric and neonatal nurses without whom I never would have made it through residency, let alone 20 years as faculty. And of course, my biggest thanks to everyone with whom I had the genuine pleasure of working with at Harbor-UCLA, in every department, in every location, in every shift. I couldn’t have done it without all of you.

A good friend said to me the other day, it’s not goodbye but see you later.

So, Harbor-UCLA, see you later.

I am excited to turn the page to the next chapter.
