The inventor of this technique is due actually a Nobel Prize! The installation is really easy, and the functionality is excellent. No more wireless, only D-LAN! After we went to our house already for about a year on the D-LAN starter without integrated power socket in the Internet, as our previous wireless was firstly lame and secondly disembarked often times is (the computer is in the rec room in the basement, and that is from super reinforced concrete, a white tank), we now have this set us bought since our daughter finally have their "own" Internet in your attic wollte.Vorab is again stressed that separate circuits within the house no problem represent, however, it is not possible, for example of the neighboring house of the data via the mains "tap"; at the house connection is the end! In addition, you should always encrypted with D-LAN to the Internet (see below). What to say: devolo software from the installation CD on one (!!), the computer install (which is required for encryption), plug the adapter into the sockets and connect via LAN cables with the computers and the router ,, the adapter numbers (glue on the back of each adapter, write down before plugging into the sockets!) enter in the devolo Informer, the adapters using the software encryption zuweisen- best automatic Option, on the computers once the let go through Network Configuration Wizard to abzustimmen- the devices to each other ready! Now that can secure as encrypted, and especially stable surfing the WWW begin! - Whoever thinks this installation description, it was indeed still komliziert, just believe me: It reads a lot more complicated than it is! The computer software titles, or "says" a when installing always, what to do or what he wants. Incidentally, these adapters are also compatible with Windows 7; which can be found in almost any product description, it is then but it also on the packaging. If only everything on the computer as simple and ingenious at the same time, then you could save a lot of time and nerves ... Wholeheartedly 5 stars because I can not forgive, it could also be 10!
