Background: We are using Aruba wireless controllers/APs (sadly, no airwave). All buildings are using the same VLAN ID for the wireless subnet, but each building has their own subnet for wireless. All APs are configured in the same AP-group. We have an open wireless network and not using any NAT (public IPs are being given out). IPv4 only. A lot of our Mac users, though not all, when trying to connect to wireless, they are able to connect to the AP, but are receiving a "No IP Address" message, and therefore cannot access the Internet. Once they leave this building and go to any other building on campus, they do not have an issue whatsoever. We have tried to manually configure the IP address, but still the device is unable to access the Internet (cannot even ping the GW). After removing the Wi-Fi option in Network Preferences and then re-adding, the device is able to get an IP from DHCP server, but is still unable to pass any traffic. We have tried rebooting the laptop, completely removing wireless network and reconnecting, and have tried booting in safe mode. Nothing seems to be working. If we connect using an ethernet cable in the same building that we're having wifi trouble in, it works with no problem. Config for the wireless subnet in the affected building is the exact same as config in all other buildings (except the subnet, of course). All buildings are using the same DHCP server. This seems to only be happening with Macs, not any Windows machines that I am aware of, nor do we have any problems with other Apple devices. And like I said, some Macs are having the issue, others are not. We only started seeing these problems within the last 2-3 weeks. The only difference we made in the affected building is giving it a larger subnet over the summer. We are working with our Aruba SE who is reaching out to TAC for us, but wanted to reach out to you guys for any other possible insight or ideas. Thanks in advance!
