Everyone with a Fritz box with built-in antennas has eg Fritzbox 7390 knows the problem of Wi-Fi range. Often it's enough just 10-15 mtr depending on development. around which Fritzbox. This problem can now be solved with the help of such 2 og cable.
On the page below the conversion is characterized precisely for the Fritz box 7390. Please note, however, that if necessary, the warranty claim against AVM invalidate. (Because Amazon does not allow direct link to the conversion instructions You must iun this Google search for it for example, enter to:.. "Conversion instructions for connecting an external wireless antenna Fritzbox" then find an entry for "DSL-Ratgeber.net" There. the conversion is described very precisely. After this tutorial I'm also proceed. There are of course also possible to have the conversion carried out by an expert for beginners.
In my case I have the jacks mounted directly on the housing of the Fritz box, so I can directly attach there the two external antennas. A previous test was this result that the range compared to the built-in antennas only significantly increased when the two antennas are close to the Fritz box at a certain angle to each other. It is important when Umbauch also that with the Fritz box 7390 BOTH antenna connections must be rebuilt because the Fritzbox sends both 2.4 GHz and 5 GHz.
PSC = 1
In my case, the reconstruction has led to a significant range. Although some tests have shown that you should slightly tilt the external antennas in a house with several floors (45 °), resulting in that the radiation work better vertically to better achieve even lower floors.
Who something is technically gifted, can perform the conversion easily.
