3 x Aruba 105 APs running 3 SSID, one corporate WPA2-Enterprise and 2 WPA2-Personal one for Mobiles other for Guest.
AP Version: 6.4.2.6-4.1.1.8_50989 (There is a new version available but I don't want to update for the sake of one device incase of other client issues)
We are using Radius Server for Authentication, the magority of other Laptop devices are authenticating well, there is the occassional connection issue but usually they resolve themselves or require minimal intervention. However a HP ProBook 430 G2 Laptop Win7 64 Prof is not wanting to connect/ reconnect to the network. "Windows was unable to connect to this network".
It has previously connected to the corp network, but after returning from the holidays it is playing up and has lost connection and will not reconnect for love nor money despite trying basic troubleshooting, resetting NIC, windows troubleshooter, removing managed network and adding profile manually, updating NIC driver, restarting device, removing the user from the Aruba AD Security Group and re-adding them.
The Aruba AP shows the client in the client table and you can see the correct MAC address for the wireless NIC of the client, but it has no name next to the IP address just '--', or another time there is no IP address either 0.0.0.0. I am trying to clear this entry from the table using the 'disconnect now' button from the Aruba WUI, but it will not remove the entry. (or it will remove it only to reappear shortly after, when I try to reconnect the client, but with the same IP or no IP).
Is there away in the Aruba CLI for me to manually clear/delete this clients MAC and IP from the client table?, just completely flush the AP of this clients information and try and reconnect?
(There is an Alert which appears occasionally also: The AP cannot receive data from this client because the integrity check of the received message (MIC) has failed. Recommend checking the encryptionsetting on the client and on the AP.)
Any questions let me now.
Appreciate any advice.
