For all those that have a blank icon in network router and the non working network map feature as it is removed from windows 8/10 (this plug and play driver bug never got corrected from microsoft, imo) here is a reg file that fixes both of the 3 problems.
Just copy those lines in a text file rename to .reg and merge with your registry. dunno if all routers have the problem but i v seen many that has it.
If this is already here in tutorials, dunno i searched but never find it.

Windows Registry Editor Version 5.00

; Corrects blank router icon

; Removes "Network Map" shell extension from 'Network' explorer

; Removes "Network Map" shell extension from 'Devices and Printers' control panel

Hope i will help someone with this
