Using two ISP's with RB 750

Hi all,
Please excuse me for the question but I’m completely unaware how to set it up.
This is the case:
I have two ISP’s which I would like to use on one PC(not simultaneously).
One will be the main and I would like RB 750 to switch automatically to the the backup ISP in case the main one loses connectivity.
Is that possible knowing that RB 750 has not 2 WAN ports?

Thanx in advance.

You can configure a second WAN port, there’s nothing limiting the 750 to only one - it’s just the default configuration. After that all the usual solutions apply (floating static routes, netwatch etc.)
