I deploy multiple IAP 207 with latest firmware as pure AP to replace existing old AP. DHCP was assigned by Firewall. After replace Aruba IAP, 2 strange problem appear
1. User notebook was connected with Aruba AP SSID WIFI running perfectly. After a while(randomly), it will then appear No internet on their notebook. When I perform troubleshooting, from user notebook I cant even ping to Aruba AP IP. Ipconfig show that the assigned DHCP IP still exist and WIFI still conected to Aruba AP SSID. I need to disconnect and re-connect again to make it work.
2. From user notebook, it always cant ping to 22.214.171.124 public IP. It intermitten able to ping but most of the time is timeout. Firewall non blocking, when using old AP. Ping to above public IP was no problem. In Aruba, no specific block rules was created
Below are my IAP configuration file for your reference.

It was connected to 5Ghz band the issue happened
What client OS is this?
The client is using Windows 10 Pro with latest patch installed. Dell XPS notebook with latest drivers install as well.
If I will connect that notebook back to old AP, it work prefectly without problem.
There is already Instant OS 184.108.40.206 out. Please download 220.127.116.11 for the IAP-207 here: http://support.arubanetworks.com/LifetimeWarrantySoftware/tabid/121/DMXModule/661/EntryId/31782/Default.aspx
I already upgrade to latest firmware 18.104.22.168 prior posting. It doesn't solve the issue.
How often does the issue occur and does it resolve itself?
Within a day it happend 3-4 times. Once it appear "disconnected" I cant even ping to Aruba AP IP or any of the IP in LAN. I need to disconnect the WIFI from the SSID and re-connect it back in order to resume the WIFI connectivity.
Now we discovered new problem. Mobile phone that connected to Aruba AP, intermittently WhatsApp cant receive and send message. However, using network diagnostic tools from mobile phone, we can ping to Google, Cisco, whatsapp.com
We need to disconnect the mobile phone from Aruba AP and connect back again then WhatsApp resume working.
