Hi. I'm new to this forum, and hoping someone here has thoughts about this issue I'm experiencing. For the past few weeks, users connecting to our Aruba 215 Access Points have been unable to connect to the internet, only to our local network. This is sporadic, happening most of the time, but not always. I've determined that when a machine is unable to connect, it is receiving the incorrect MAC address for our gateway. The last octet is off by a value of one (9a instead of 99). Flushing the ARP cache on the offending PC usually resolves this temporarily, but it eventually happens again. Sometimes I need to 'arp -d' several times before it works, sometimes it doesn't work at all, and sometimes the PC will eventually just reconnect on its own. This does not affect any of our wired workstations, so I'm pretty convinced the APs are at fault here. Any idea what could be causing this?
