I have 4 Instant AP 105 units up and running. The up and downloads on them are a fraction of the capacity compared to the same laptops being plugged into the network.
I am seeing speeds around 3mbs on wireless vs 100+mbs when wired. These are speeds copying from a fileserver that is on the local office network. Some clients are coming up with weak signal, but show good speed, including the laptop I am using, which is about 8' from a ceiling mounted unit.
Security is WPA-2 Enterprise and is auth Radius against a Win2008R2 server
2.5 and 5 Radios are set to adaptive assignment.
Aruba hardware is new to me, so I am not sure where to start troubleshooting the units. I did read through the forums and saw a few things to try like setting the channels manually incause of interferrence, which could be the case on 2 of the APs but not the other 2.
