A Verizon installer said that to use FIOS TV with 3 TVs, each with its own set top boxes or DVRs, we must lease a Verizon brand (wireless) router to split the cable TV signal. Otherwise the set top boxes or DVRs will not initialize correctly. Is that true, or can something else legitimately split the cable TV signal to feed the various set top boxes or DVRs? E.g., an ordinary splitter, or two-way amplifier and splitter? Also, if we also get FIOS Internet, can we use a non-FIOS brand router to split the Internet (100BaseT ethernet) signal to multiple wired computers, or must we use the FIOS brand router for that too? Thanks.
