We have a client with 90+ locations who has sporadic issues with Apple devices not being able to authenticate against their WLAN. Each location runs the same device, same SSID & Password.
The senario is the device will prompt the user that the WLAN password is incorrect and regardless of what you do with the device it fails to authenticate. The only fix is to make any change relating to wireless on the device; below is a list of things that we find bring it back online.
- Disable/Enable WLAN
Change Mode AP Bridge > Station > AP Bridge
Change modulation type
Change Security Profile items
- Firstly had her try connecting and it was showing incorrect password
Had her restart the iPad and try connecting on her own personal iPhone while the iPad was restarting. Her iPhone has never connected to a Customer-SSID AP before yet kept showing incorrect password (tried twice)
Had her try connecting the iPad after the first restart – was getting the error message “Unable to join the network Customer-SSID”
Forgot the entire Customer-SSID network and restarted again (second time)
Tried connecting to the Customer-SSID network after restart – incorrect password
Forgot all network settings on the iPad and restarted – still getting wrong password
Tried connecting to the shopping centre free WiFi – connected instantly, working fine
Tried reconnecting to the Customer-SSID network – incorrect password
Finally I had the other girl working at the site try her own iPhone too (also never connected to a Customer-SSID AP) and it also gave her incorrect password without fail
These devices were all provisioned with FlashFig and happens randomly to devices it has not occurred on before and also reoccurred on devices multiple times.
