So i live in an area that doesn't have fiber but has decent 4G/LTE connection. The problem is we have one service with unlimited data between 11pm and 6pm the following day and another service thats pre-paid. I want to connect both dongles to my pi and have the pi connected via ehternet to a router. At a specific time I want one dongle to be disabled and have the other one enabled and vice versa. Is it possible to do this? I know I can route the 4g connection through my wifi router via wan, but can I disable one then enable the other after 6pm and after 11pm?
