I have a Netgear Nighthawk AC1900 Smart Wifi Router (R7000) routing traffic for a approx. 30 Ubiquiti AP-LR access points. It is working really good at the fixed Class C configuration but would like to increase DHCP capability to a class B. I currently have 200 IPs available to clients through dhcp but 500 (+a few) would be ideal. Can this be accomplished with the latest DD-wrt firmware? And, if so, how do I configure? GUI? Command line?, etc.
Thanks in advance,
Voyeur
Never tried it, but we added a patch before that should allow this, currently you cannot configure this via gui, but if you confirm it is working I'll update the webif field in order to be able to set the value.
Thus try the following, login via ssh and run command:
nvram set dhcp_num=500
nvram commit
reboot
if you look at /tmp/dnsmasq.conf it should have the appropriate entries now.
What about subnet mask? That is really where the issue is, will the above command reset the mask to the proper value?
A class B is 65,536 IPs. You just need a couple of class C's. Try netmask 255.255.254.0. That will give you 2 class C's - 512 IPs.
