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 18.104.22.168.624. 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.
Smartzone carries the firmware upgrade for the APs. So you can't upgrade the APs without first upgrading the Smartzone. You can leave the zones at their level (AP firmware) and upgrade as you need to, as zones have their own firmware settings separate of that of the Smartzone itself.
