I'm not sure what the lease time is set to, How would I check this? (The router's web interface has no option to change it)
Devices are able to connect to the router, they just expereince a disconnect every 20 minutes or so due to the NAK and then reconnect in less then a sec.

What is the configured lease time for IP's that the router hands out?  Just a
thought, but it sounds like it might be set very low.  The NAK might be because
your device is requesting a lease time that the router determines is
unacceptable.
