Model : TL-ER5120

Hardware Version : v2

Firmware Version : TL-ER5120_V2_140212

ISP : Comcast Xfinity

this router has been working with zero problems until about three weeks ago
it is connected to comcast cable via WAN1 port
comcast reports no issues on their end
internet drops multiple times per day; usually comes back by itself within five minutes, but other times it does not
will reconnect if the router is rebooted
wifi remains live throughout
latest firmware installed
what is happening???

Wifi? But the 5120 has no wifi function. What is the topology of your network? And is there any error message in the log of the 5120?

Agreed, 5120 has no wifi, I should have more accurately stated that the LAN side is still fully operational (I have several WAPs hooked up).

I am using 2 WAN ports in a failover configuration, cable on WAN1, DSL on WAN2. 1 LAN port connects to a TL-SG1024 switch and the switch is connected to a few WAPs and a some other devices.

A few minutes after the connection drops, the log says:

WAN1:DHCP releasing IP address xxx.xxx.xxx.xxx succeeded.
 WAN1:DHCP send DHCP-DISCOVERY timeout.
 WAN1:DHCP getting IP succeeded, and IP addr:192.168.100.10, mask:255.255.255.0, gateway:192.168.100.1. ***IP address doesnt make sense; connection still down
 WAN1:DHCP getting IP succeeded, and IP addr:xxx.xxx.xxx.xxx, mask:xxx.xxx.xxx.xxx, gateway:xxx.xxx.xxx.xxx. ***IP address seems right; connection back up

Hi people, sorry for my english, i write from Argentina.

I have a problem with a TL-ER5120 V2. It has 2 Internet connection, and almost every morning the internet doesn't work. If a do a ping to the router, it reply ok. But internet doesn't work and I can't connect to the admin panel of the router through the browser. If I reboot the router, the problem is solved.

I need to find a final solution for the problem. The firmware is up to date.

Thanks,

Fernando.
