I have a small network of 3 computers cabled to a router and from there to a cable modem and the internet. When the cable service goes down, I’d like to be able to switch the router over to a cell phone configured with a mobile wifi hotspot for WAN access, ideally with a physical switch on the device (for simplicity). The router would be expected to function (i.e. no configuration difference) regardless of which WAN interface was being used. Can anyone recommend a SOHO router with positive reviews that provides this? thanks.
