I have a peplink balance 30, firmware 5.4.9 build 1732. Attached to the 4 LAN ports are 3 devices, plus another router. The router is actually in another room of the house, connected by an ethernet over powerline adapter, if that matters.
Two wans <–> Peplink balance 30 <—> Ethernet over powerline ----powerline----Ethernet over powerline <----> Another router
The peplink has IP 192.168.3.1 as gateway. The router “Another router” has 192.168.1.1 as its gateway address.
Occasionally, the 3 devices attached to the balance 30 stop using their assigned 192.168.3.x IP address and suddenly acquire a 192.168.1.x address. I guess this is at time of lease renewal because it happens to all of them at the same time.
This results in loss of internet connectivity.
I solve this problem by disconnecting the powerline adapter from the peplink, then release/renew IP of the other devices. They then go back to 192.168.3.x as usual. If I just release/renew without disconnecting the powerline, they just get another 192.168.1.x address. @_@
Anyone have any idea why that router is serving DHCP to these other devices, and how to stop that?
