dose anyone has an idea why R510/610 will suddenly stop forward broadcasts (arp) via radio. and after restart broadcast forward again. we have SmartZone with several ap (different zones).ap firmware is 22.214.171.124.624. in some sites, we encounter this issue. suddenly we cant reach some devices and we notice that the arp table didn't include the target IP. when adding a static arp entry to source device it was able to reach the target device. resetting the ap (the one that the target device was connected to) the issue solved foe a while.
