I had set up rv042g to Smart Link Backup mode. but sometimes wan1 link is "flashing". E.g. it has short time link downs which may last for a loooong period. And every time wan1 is up, router switches back immediately. this leads to fully unworking internet connection.
The question is: can i set up the time that router guaranteed will be switched to reserved link. for example it will be switched at least for one hour after wan1 is down?
Here is part of my log to illustrate the problem:

Dear Roman,
Thank you for reaching Small Business Support Community.
I understand your concern and unfortunately I see no way to configure the failover the way you wish. Just in case you can contact the Small Business Support Center for further assistance;
https://www.cisco.com/en/US/support/tsd_cisco_small_business_support_center_contacts.html
Please let me know if there is anything I may assist you with in the meantime.
Kind regards,

Why don't you desginate your WAN 2 as the primary WAN and if it fails it can use that connection that keeps dropping all the time?
But more realistically, if your WAN 1 is dropping, it may be best to call the provider. That seems to be an unacceptable behavior.

Many thanks for your for your attention. This dropping-all-the-time behaviuor occurs not so often. It can be somehow connected with LTP settings of internet provider or something else. I cant just switch router to secondary wan because about 80 devices wil try to connect to wan1 for 1 minute and after that will switch to secondary wan. It needs much time to change their settings.
I understand that this drops looks like unacceptable behavior but i thought i could be protected of it by the means of Cisco router. And now i see that even Cisco router can do nothing. I should by mikrotik instead.

Thanks for your reply! If you see no way to help me. May be you can just describe by what algorithm the failover occurs. By what timings and what settings take effect on it. Does this behaviuor changes at different version of firmware? May be i can control failover by the means of SMNP? Is there any helpful advice i can get from technical support or it will be helpful "as usual" ?
