One of each seems a little excessive for an @ home worker.The advantages are stated above.
What's the advantage?
And is it worth the added expense.
And yes, it is worth the expense for anyone who needs an always-on connection.
Especially even more so given everything else we do is over IP - VoIP calls, music & video streaming, CCTV, etc. No antenna/satellite signal TV viewing here.
Helps keep good neighbourly relations too: both sides to us jump on our guest wifi network when their VM gets congested in the evenings.
I'd describe Virgin Media as high bandwidth, high latency and our FTTC as low bandwidth, low latency. Best of both worlds. Our VM goes down whenever it rains heavily and we are fine given the other line.
