Just deployed a TL-ER5120 to load balance two WAN connections on Tuesday.  Encountered this issue since the isntall where the DHCP service stops after about 20-odd hours of router uptime.  It stopped on Wed afternoon, rebooted the ER5120, and stopped again this afternoon.  The only difference is that it does not come up again.  Besides the DHCP service, the unit appears to work correctly.

The DHCP configuration is pretty much default, about 12 address reservation (2 are disabled). The DHCP server is only configured with a starting and ending address range and a lease time of 2880, and the status checkbox ticked.

Nothing in the log.

This is a V3 unit running 3.0.2 Build 20180125 Rel.35267

Hi,

I have recently deployed TP-ER5120 load balancer router in my office and since then once in a day all my notebooks are failed to get IP address from DHCP (configured on TL-ER5120) and it is fixed after 20 to 30 min's on it's own.

Please let me know if anyone has faced this issue or any fix for the same?

Thanks
Saurabh

Hi Saurabh

If you use ER5120 V3 as well, you can try to upgrade the latest firmware.
