Question about billing plan offer.

So i wanted to pay my bill and somehow get credit and cash back on rakuten for doing do, but I think that's asking too much, anyways on to the question. I currently have an internet service plan of up to 200 mbps download speed for 39.99 a month and plus 14 for modem.

But since I have rakuten I decided to browse some deals and the very next tier up is 69.99 for tv(10 channels) and up to 100 maps download speed. I would of gladly taken the deal if it was 200 mbps. But it wasn't, so that kind of did not make sense. So i thought if this deal continued after my current deals price ends which is this October, I probably would take it. But is it really? what I mean is does it start now or next October? Because it never said but it was the first deal listed.

Also. I wanted to know, this is more if a technical question but I would like to use the yellow internet cable they gave me instead of wireless for a faster connection, but i don't seem to have a input for it anywhere? Can someone explain to me?
