Hi,

I have a draytek 3900 with 3 VLANs. This connects to an AP910C access point. I have a few wifi temperature sensors on VLAN3 but they are having the DHCP declined. When i look in the ARP table i can see the mac address for the sensors is connected to a different VLAN which i`m guessing it is why it is failing.

Can i clear the ARP cache table and what will this do? I have tried clearing the individual ip addresses from the table but it doesn`t clear them.

Any ideas?

Thanks

James
