    Hi All,

    We are facing issue with few clients of specific adapters facing disconnection issue frequently with ! mark.We upgraded the NIC driver version but no luck. We could see 1 thing from pcap that is client sends continuosly requesting for ARP to gateway though it gets response from its gateway. Anybody have faced it or any clue...?

    Please look at the article here:  http://community.arubanetworks.com/t5/Technology-Blog/Removing-the-Bottleneck-in-Wireless/ba-p/77978 for ideas on how to optimize your wifi, because the ! could be a side-effect of that.

     

    EDIT: I would also consider upgrading to the latest 6.3.1.x to see if that fixes your issues.

    Thanks for sharing the link. Unfortunately we could not plan for the upgrade since we have old ap model still live in network. If we upgrade the controller to 6.4 version then they (ap-65) will disjoin. Is there any relevant bug in 6.3 available..? We are also planning for raising TAC with wifi nic card OEM..!!

    You can upgrade to the latest 6.3.1.x.

    We do not have enough detail to know if your issue is caused by a bug or configuration issue. Please open a case so they can look into this.

    We raised TAC and got to know that ap's are dropping the ARP response packets those destined for clients. Escalated to engineering team of aruba to check..
