Gyuri Thank you for your caring comments :) I was able to install the plugs with the following procedure. This is especially crucial, so it would be best, if you write it to the description of the item.1) You will not be able to install the plug successfully if you have a simultenous 2,4 and 5 GHz band WiFi router.2) Switch off the 5 GHz band, if it is switched on.3) Install the plug as written in the manual.4) You can switch on the 5 GHz band after the successful installation.I did it so, and my plugs are working fine. Already oreded a third one too :)Cheers,Gyuri
