I'm having some problems with my ADSL router DrayTek Vigor 2600 Plus. After a few days and some people connecting to it, it stops assigning IP addresses to new people that tries to connect.
I was hoping that reducing the DHCP lease time could improve something.

Anyone knows how can I change that in this model?
I was also looking for the user guide on the internet, but couldn't find it anywhere. It would be great if someone points me to the pdf.

srv dhcp leasetime [xxx]

You can see it in draytek site:

Ok, mine was set to 3 days!!! I've changed that to 3600 seconds. Let's see how it does. Thanks. – Nelson Reis Mar 25 '10 at 12:26
