RV042 Failover does not work properly in certain WAN1 signal condition

    Our RV042 has cable modem in WAN1 and ADSL in WAN2; it is set in smart link backup mode.

In certain cases of WAN1 signal loss, RV042 seems not to detect this condition. Consequently it does not switch automatically to WAN2.

One way to get it to switch is to disconnect WAN1 modem power (manually in situ), then WAN2 assumes as active link.

We conclude that, in the mentioned cases, although WAN1 signal is not good enough to provide internet service, RV042 makes a wrong decision and determines WAN1 is ok.

Is there a way to have a correct switchover for these cases?
May be with a firmware fix, or an internal user programming/setting, or different router model- or a combination of these elements, or any other solution you can provide us.

Hi Eduardo,

In the cases where you mentioned WAN1 has a signal loss, this means that there can be no internet connectivity correct? If so, you can set the router to ping a remote host and to remove the failed connection when WAN1 has failed under Network Service Detection in the Dual WAN section.

Hi Jagor,

Many thanks for your answer, it focus us in the solution.

It also helped us Doc Id 108603 that brings rich details about settings.

We're about to change settings and will see if problem is solved

As was mentioned in the earlier post I would make sure that the Network Service Detection is enabled under the System Management Tab and also choose the Remove the Connection option. The latest firmware for this router is 1.3.12.19tm.

THANKS

Hi Riroe,

Many thanks for your help.

This additional information confirms our procedure.

Also it warns us to update firmware to last version.

Eduardo,


It sounded like you have the device setup properly, however under the system management tab, it has the ways it will detect if there is a disconnect.


If you have wan 1 and wan 2 set checked beside the default gateway it will ping the gateway and if it gets a reply from the modem, it will stay connected. 


You might not have internet connectivity, but the router thinks you do cause it can ping the modem.  If you uncheck this and set it to remote host.  Then


set wan 1 to www.google.com and wan 2 to www.yahoo.com.  This way it has to get all the way out to the internet to resolve internet names.  If it can't,


it starts the failover process.
