Good and stable cable router?

Search one (prerequisite

1.guten
2.stable (from the compound and not too big variations in speed)
3. Reliable (no crashes be it in the Wi-Fi or in the LAN)
4. (optional) future proof
5. Relatively new on the market because of point 4
6. Flexible because of extension of the Wlan (mesh, dlan etc from other companies) must be extended with us because of large apartment

These are the basic requirements

Must be cable router because we're at Unitymedia and a 400,000 line down and 20 up
5 cell phones and 1 laptop in the wireless

stood Pc, TV Box and Devolo (because of WLan) in the Lan
What did you experience and what would you recommend if the price does not matter (own experience or known, not the main thing the newest (except you have the experience with it then ok)

First, make sure that the internet connection is stable. If that is not so, then brings the best router nothing.

And if, then I would something like FritzBox 6590 o.Ä. Recommend.

The quasi-standard routers are those of AVM:

to 2) A cable connection always has different speeds because it is a "shared medium", i. A certain number of users in the cable network share a bandwidth. In the prime time, when everyone surfs violently, etc. Kan can speed down drastically.

This is not a mistake, but the basic technical construction in the cable network (with VDSL you have the problem not!).

to 6) To be able to use Mesh, all devices must come from one house, cross-manufacturer does not (yet) work with Mesh.

You meant cable connection is a shared medium. In the contract is min 140,000 that means it must also arrive at least as much Prime TIme and shared medium back or not or not? What do I do when Unitymedia does not fulfill the contract?

So with the Telekom you get the equipment with the contract to match delivered, a large selection is not there. At present one tries to bring only newer devices to the man and argues due to the further development of glass fiber nets already in the direction of server plants for the private home of the users… Well, that is probably somewhat exaggerated for the normal consumer, however, the distributors speak after nothing against the in the first place still distributed WLan devices of the Telekom. That's to say: one wonders already, one meets with doorstep shops on before still only with cable Routers equipped homes of the users and advertises already for substitutions at the devices, around the home in a more modern radio operation, after the standards of the specially renewed routers Devices. So you have to be careful not to do the same thing again, albeit with the promise of a generally better available bandwidth… But do you really need it yourself and to such an extent? I do not think so. Nevertheless, the ports for an almost real wiring of the router disappear more and more and you also connect the TV box (Unitymedia, oä.) In such a way, then the built-switch in the device barely enough to the entire network to transport or handle. Good if you have a computer that relieves the network through its own switches. In principle, the routers of the Telekom at their magenta tariffs are also always WLan-suitable, but at first probably only to be able to help over such problems if necessary in other ways. If necessary, you run a WLan to its cable network, because you realize that the ports on the back of the router are already fully occupied and offer TV box as well as TV itself to enter a WLan operation. Really smart, this does not seem to me though. The page of the Telekom among the telephone and InterNet offers of the series Magenta, presents the various devices however also figuratively and together with all their functions for their customer of tomorrow. It is always worth reading or even printing!

If at least 400 MBit / s arrives at 140 MBit / s, then it is contractually regulated and in order.

Shared medium here means: You can sometimes get 400 MBit / s, but sometimes only 140 MBit / s - there's no permanent speed, it just fluctuates, depending on the use of the cable bundle by all users of the bundle.

what do I do because Unitymedia does not fulfill the contract?

Then you can, for example, Contact the Federal Network Agency.

What does this, somewhat gloomy answer have to do with the question? The FS already has a cable connection…

That has as well as nothing to do with my question in addition I'm Unitymedia that is cable Internet
