We are implementing a new redesigned Aruba network and are also experiencing this issue. We have older AP61 but are running 6.1.3.3 Aruba OS.
If our wireless clients connect to a outside "Linksys" AP they get full network bandwidth but if they connect to our SSIDs they get average of 1 Mb down / 9 Mb up.
We have multiple ISPs:
1) 9 Mb down / 9 Mb up
2) 20 Mb down / 6 Mb up
2) 200 Mb down / 200 Mb up
The clients get the same speed on any of the SSIDs and at this point we only have (1) AP connected.
Any help would be greatly appreciated ....
