Hi,
I have 2 Linksys WRT1900ACS routers (installed on opposite sides of office space) and OpenWrt Chaos Calmer 15.05.1.
WAN connected to corporate LAN on fixed IP.
2 WiFi networks on each router (in 2 zones), LAN for employees and GuestLAN for everyone else.
Very standard configuration for DHCP
Router #1 - WiFi A 2.4 GHz, WiFi A 5.0 GHz (192.168.11.x), GuestLan A 2.4 GHz (192.168.12.x)
Router #2 - WiFi B 2.4 GHz, WiFi B 5.0 GHz (192.168.13.x), GuestLan B 2.4 GHz (192.168.14.x)
GuestLAN have restrictions, like ping, blocked SSH, SMB, etc to LAN & WAN.
Now the problem. DHCP server seem to hangs time to time. Overview shows few active DHCP leases (far below limits), activity indicator blinking, yet no actual traffic go through WiFi. Attempt to connect new DHCP client results in bogus (non-existent) IP address.
DHCP lease time is 12 hours.
What could be the problem ?
This particular router is very popular, so possibly I'm not alone with this issue
