TL-R480T+ "Online detection failed" for ever
Model :
Hardware Version :
Firmware Version :
ISP :
I was trying to ask this to tech support, but they just closed the chat after reading the question - my first experience with TP-Link tech support!
I own this TL-480T+ recently and was trying to use it between two internet connections - WAN1 as primary and WAN2 as backup. WAN1 has a daily data cap, and after that it disconnects from internet - basically ping failure will happen (to 8.8.8.8, which I manually configured). Then it is expected to switch to backup. This works as expected and WAN1 will be marked as "Online detection failed" - which is perfectly true.
The issue is at midnight, once the data cap is reset, ISP connected to WAN1 will be again active. The test IP address 8.8.8.8 will ping again. However, the router won't honer that and stays forever as "Online detection failed". I need to go, disconnect WAN2 cable to force it back to WAN1. This is not what is expected.
Do anyone else have this problem? I do manual online detection, only using ping to 8.8.8.8. DNS lookup based online detection is disabled on purpose. The ISP CPE has captive portal, which spoof any DNS request (while disconnected from internet) and respond back with its own IP - which will trick the router unless I disable it.
I could have lived with this issue if there was a shell based or API based facility to disable/enable selected ports. I should have configured a script post midnight to disable backup WAN for few seconds to wake up primary and then enable backup - however I don't see any way to disable/enable ports except physically disconnecting the cable. Is there any such facility which I am missing?

A solution for wrong "Online Detection" use ?
Hi,
I've got exactly the same issue with my 480t+ !!!
It's because of the include firmware test process which can not use the right value... They will have to use « Port Status » var and not « System Status » var when the user activated the « Online detection » with « Link Backup » .
If you're looking at var in your TP LINK console you will be able to see... when adsl signal input is down for a modem (ex : WAN 1)
:
Status / System Status
WAN 1 / Connection status = Link Up / => With the ping test it should have to be down !!! :confused:
WAN 2 / Connection status = Link Up / => Normal because of the "link backup" option
Transmission / Load Balancing / Online Dectection
WAN 1 / Port Status = Offline / => Normal because of the ping test NOK
WAN 2 / Port Status = Online / => Normal because the second modem is up ;-)
We should be able to read this :
IF WAN 1 / Port Status = Offline => WAN 1 / Connection status = Link Down
NB : Even if the link is physically active, the WAN is unusable because no adsl signal !!! So "Link Down" and full switch to an other WAN with "Link Backup" option otherwise, dns issue few minutes after the adsl loss from modem/router input...
Please, have a try with your hardware ;-)
So, TP LINK developpers.... juste need to change a simple var in the "system status" test... use the "Port Status" if test ping activated
PS : Sorry for my english ;-(

Re:TL-R480T+ "Online detection failed" for ever
Hi,
The only way I had found to make my TL-R480T+ work (a kind of bad link backup) was with this params... thanks a lot Murphy from Tp-Link support : [EMAIL="support.smb@tp-link.com"]support.smb@tp-link.com[/EMAIL]
Network => Screen copy (wan1 & wan2)
No bandwith control
No session limit
Basic Settings => Screen copy
No Link Backup
Online Detection => Screen copy (wan1 & wan2)
Hope it will help you...
NB : WAN2 down / upstream bandwith are setting =100 because I want that WAN1 is priority ;-)
