    No problem. If you have problem with WiFi you should check also the channels of your WiFi network (especially channel width). Maybe your neighbour use the same channel… All the best!

    For newer Wlan adapers and Wifi-routers, you could best set your Wifi-router to the 5MHz band, instead of 2,5MHz. Also it is better to change the standard 20MHz carrier to the 40MHz carrier signal-width.

    Very usefull tool, this measuretool for signalstrengt!

    God Bless

    ps: I only know the European standards. Wifi has in EU 13 channels and in the USA 14 channels!
