I have Aruba IAP 225's in my school, with 200Mbps bandwidth. The speed of my MacBooks is great. My PC's, however, are very slow. They are running a download speed of less than 50Mbps, and upload of less than 20Mbps. I have restarted the DNS server, AP's, and switches. I have also restarted DNS and DHCP services. The AP's have the latest update installed on them. The PC's have the latest updates on their NIC cards. Any ideas what would be causing the slowness on the PC's? Thanks!
