Hi,
Since the devices are purchased through Dell I have to open a case with them which I have. They inturn opened a case with Aruba.
Now that was 4 days ago and I have gotten no further with them, basically the assistance has been minimal, no trouble shooting steps have been offered at all, simply some questions asked.
We have investigated further and now seem to be able to reproduce the problem.
Firstly the iPhones use and Enterprise SSID, and connect on the 2.4Ghz band and obtain IP addresses from the AP's.
Laptops use the same Enterprise SSID but connect on the 5Ghz band and obtain IP addresses from the AP's.
To reproduce the problem we turn on a particular HP printer that uses a different SSID , WPA2 Personal SSID.
It connects on the 2.4Ghz band and Obtains its IP address from our Company DHCP server, so its a different subnet to the iPhones and laptops. When we do this the iPhones will almost immediately disconnect from the WIFI network.
Also the 2.4Ghz Utilization percentage will increase to > 60%
If we turn the Printer off again the iPhones recover.
If I change the Personal SSID to obtain IP addresses from the AP's then the problem does not occur.
Any clue why this would be the case?
The Printer is part of a Scientific instrument LAB which has 3 other computers attached to instruments that also use the Personal SSID.
The reason they are on a different SSID is so they can obtain IP's on the same Subnet as the rest of the company.
The only reason for that is so Remote office users can Remotely connect to the Labs Instruments via the computers.
I cannot figure out how to enable the remote connection if the Lab Computers are not on the same subnet as the rest of the company.
Remote connection can be via VNC, MSRA RDP etc.
Any help appreciated.
