Does Cable Effect Internet Speed?

[tendererdegree]

So we don't have cable now and my dad wants to get it.

 

Since my modem and the cable box both run on coax cables, does my isp allocate a certain amount of bandwidth to the cable and internet on the same line?

 

im just worried that if we get tv that our max internet speed that we got before will never be reached again.

Like, Digital Cable TV service and Cable Internet Service?  No, it's fine.

They travel on the same line but at different frequencies and don't impact each other.

Coax has a very wide frequency range capable to carrying all those signal without interfering or causing one to be limited in anyway.

No, the cable television signals won't degrade your internet speed. As long as you pay for the same speed as what you have now, you'll get that speed.

They use different frequencies to deliver TV and Data. If you look at your modems status page, you would see X amount of Down Stream channels and X amount upstream channels. The picture below shows how its supposed to work. Theoretically Docsis 3.1 can give speeds up to 10Gbps down and 2 Gbps up. So you see there is lots of room.
