I have an asus rt n18u router, can I connect a smart bro lte pocket wifi to it? meaning, at present my internet connection is thru PLDT dsl....questions:

1. Can I have a dual source of my internet access, one thru pldt mydsl and the other thru pocket wifi LTE both connected to my router then to my PCs?

2. Can I have my dsl disconnected altogether and use only the pocket wifi LTE connected to my router then to my PCs?
