We are having an issue at our college campus Health Services building, where the doctors and nurses are using an RDP session into a medical server. One doctor for example, when she moves from her office to the exam room, she often loses the connection. This has been an ongoing issue at this building and I am hoping someone might be able to shed some light on potential causes.
There is another issue on campus involving some iPads that are connected via our Secure WiFi and are using our VPN to be behind the firewall, since they are used in the Counseling Center for filling out sensitive forms. The problem here is that the VPN disconnects due to "no network connection" (or something similar to that), and it is not possible to reconnect the WiFi and VPN without exiting the app (KioskPro Lite), which loses all data in the form. We are unsure if this is related to the Health Services issue, but it seems to be consistent in that building, since we have two Counseling Centers and they swapped iPads and the problem persisted in the same one. That building has two AP-325s (one on each floor), and is fairly small.
Things that may be helpful to know:
-We have an Aruba "Master" controller as well as two "Local" controllers
-We use all Cisco gigabit ethernet switches with 10gb fiber uplinks
-We cleaned the fibers relating to the controllers during a break between semesters.
-We have a gigabit connection to the rest of the internet.
-The doctors are using our Secure SSID or the Eduroam SSID (which is functionally identical)
-The building (Health Services) has 7 indoor AP-225's in a single group, all using the same controller (as well as an outdoor AP-175P in the OutdoorAP group).
-We have increased the minimum data rates so that the lower ones (I believe 1 and 2 mbps connections) are no longer available, to reduce sticky clients.
-I put a support call into Aruba TAC about another issue, and we enabled MPDU Aggregation, which was causing our wireless speeds throughout campus to hover around 45-50mbps (after enabling, they went as high as 450-500mbps).
-The Health Services building is wood structure with drywall, has two floors (only above one half), and is not very big (two floors on one side, just one floor on the other).
-There seems to be sufficient coverage in Health Services, as there is an AP directly above the doctor's office, one in the lounge area she walks through, and one in the exam room itself.
-These problems seem isolated to their respective buildings, but have been ongoing for some time now.
Please let me know if further information is needed. I would greatly appreciate any help!
