Cable internet: high data rates on a shared network

With cable internet you often get high download speeds. First look at the load in your network segment, the upload, the router standard and the price after the discount period.

Cable can deliver high download speeds. Because households share network capacity within a segment, it is especially worth looking at experiences at your specific location and at the guaranteed bandwidths.

Its strength is the download

For large downloads, several streams and many devices, cable often offers a lot of performance for the money. If you regularly upload large files or need particularly low latency, compare the upload separately.

Checking at building level

An existing cable connection in the building does not automatically mean that every flat can be connected straight away. Clarify the socket, the in-house network and any additional agreements before signing a contract.

  • Don’t overlook the upload
  • Check the router standard and Wi-Fi features
  • Calculate the price after the discount period
  • Give experiences in your specific building more weight than general reviews

Frequently asked questions

Does cable internet get slower in the evening?

On a cable network, households share the capacity of a segment. If that segment is heavily used, the data rate can drop at peak times. How noticeable this is depends on the specific segment – so experiences from your own building or street tell you more than general provider ratings.

Why is the upload lower than the download on cable?

Cable networks are technically asymmetric: most of the capacity is reserved for downloads. For streaming and normal browsing you will hardly notice. If you regularly upload large files, run cloud backups or spend a lot of time in video calls, compare the upload figure specifically.

Do I need a telephone line for cable internet?

No. Cable internet runs over the TV cable connection and does not need a telephone line. If you want telephony, it is provided as internet telephony over the same connection. You need a working multimedia socket in your flat.
