Net Gear DHCP not working

Hi,

We are using a Net Gear DGN2200v4,   DHCP enabled.

 Default ip range is 192.168.0.2 thru 192.168.0.254.

Default IP 192.168.0.1 -(modem address)
Gateway:  255.255.255.0

Currently there is 17 devices on the network.   I can't add more.  According to the IP range, I beleive there is 252 free IP addresses.   5 minutes ago I was unable to connect with my smart phone.  I disconnected a laptop, and then I was able to connect my smartphone, so this confirmed that the router is only allowing 17 devices.  Any ideas?

Here is the user guide, didn't find anything stating device limit, is ipv6 enabled on the router, try disabling it.

Try upgrading firmware, if that doesn't solve the problem, I would suggest contacting support, if the router is provided by ISP contact them first and ask for replacement.

Have you monitored what is going on via the GUI / Dashboard?
Can you see only the 17 devices attached with the laptop being replaced by the phone in the list?

DHCP pool set correctly? Any reservations in there?
When a device is not working is it definitley a DHCP issue rather than a connection issue?

One more thing you can try is to lower wireless settings from 802.11n to 802.11b.

No idea why it would only allow 17 devices when its set like that.. can you repeat your test results with other "18th" devices? (i.e extra laptops / PCs).

Do the 18th devices get connected to Wifi but no DHCP or just not connecte to Wifi?
Can you add more devices connected via ethernet rather than wireless?
