Right at th outset let me say I have read the sticky above but I don't think it covers what I am trying to do.
I have a network which uses a TP-Link 3420 3G router. I want to add a second router to give me fallback to an alternative ISP (I am installing this in Africa and the ISP service is patchy to say the least). The TP-Link has the facility to switch between two internet feeds, the cellular modem and a wired connection into the WAN port on the router. I want to connect a second TP-Link to the WAN port on the first, my issue concerns DHCP. If I leave DHCP enabled on both the whole thing gets into a terrible tangle (as you might expect). It actually sets the first one to a 192.168.1 subnet instead of 192.168.0 and the only way out appears to be a factory reset. However if I disable DHCP on the second router I can't seem to communicate with it, even if I fix my PC's ip to the same subnet. Can anyone help me please
