Hi all,
many of our customers still are having “DHCP-server assigned and deassigned” issue, with result their devices cannot connect to network/internet.
We use rb711/911 as CPE with dhcp server (last release RoS) and other vendor AP like wifi: tp-link, ubiquiti, netgear…
In fact the problem occurs only in wireless network.
I understood the problem appears when:
device must renew the dhcp lease
in the network exist almost a new mobile phone apple or android (samsung)
I think there is a kind of incompatibility with these new devices when they must renew lease, and, I don’t know how, it ends up to create problems for the other devices…
The number of customers asks us support is very high, and I don’t find a solution yet.

Make sure your pool isn’t running out of addresses. Whenever you have a network with lots of transient users (they all have 3 devices with them nowadays, right?) you might need to use a larger network than /24. Try using a /22 network such as 192.168.0.1/22 (netmask for /22 is 255.255.252.0) You could also shorten your lease times to 2 hours or something like that.
