Thread: 2 internet connections - 2 routers - and sharing folders

Hi all, my network has changed a bit, and now have 2 routers (one has a 7.5mbps internet connection using ADSL, the other connects using a 1mbps PPPOE interface). Both routers are wireless. What settings do I need to configure so that these 2 internet connections do not conflict or randomly crossover from one computer to another? I have a file server, CCTV DVR and printer that I want all computers on my network to still be able to access. As there's only 1 PC on the ADSL router, should this computer and/or router be manually configured? If so, what settings do I need? This computer will be the only one using the ADSL connection, and it will be using it wirelessly. Please see my network diagram below for more info. Any advice much appreciated

I cannot see the Diagram.
