Situation driving me mad really!! We do have Aruba IAPs in our office and Macbook DNS (I guess) issue. So client connects to the Guest wifi, enters name and email address, receives an IP address and DNS setting all good as should be. Internet access for a minute then suddenly no DNS responses seen in the PCAP file. So it doesn't matter if l am using internal or external (22.214.171.124) DNS server it is on random basis stops working (means client send a query, can see in PCAP but no response back). Then it is starts working for a minute and again no DNS resolution for 2-5 minutes. All this time device is connected to the IAP no problems there. Don't know what to think? Below the PCAp snapshot with only one successful request:
Any similar issue?
