Dear Naija,

There are 'real' dual wan or quad wan routers that enable you to connect spectranet, swift 4g, ipnx mobitel etc to a single router for a single network for load balancing on a large network or small network. It has a failover over system. if any of the network fails, the internet access continue on the active link, when the failed link is restored, it automatically joins the system. This guarantee a very high availability. The firewall and bandwidth management is also good.

For more information contact me on 08033737534 or 07082375805
