We have a problem with a couple of customers who have a high throughput of transient WLAN users - it is important that the service is available, but what is happening is that they run out of DHCP leases. I believe it is possible to change the lease time using the telnet interface, but I am not sure of the format in terms of what units the value is in - seconds, minutes, days? Ideally we would like to be able to flush the DHCP table on a schedule - recycling the power appears to leave the table untouched.The only way I have found to do this is to disable the DHCP server, restart, then re-enable the DHCP server and restart which is entirely manual and time consuming. Any suggestions would be welcome.
