Hi,
I have probably found a bug in netscan 64. Please have a look on theses screenshots:
On one of the screenshots the range is 192.168,0,1 to 192.168.1.256 he find not 192.168.1.1
If I set the range to 192.168,1,1 to 192.168.1.256 he find the 192.168.1.1 (the router).
The config is ... 192.168.1.1 is the router 192.168.1.3 (and 13) is an access point with 2 IP numbers the rest are network computers.
Netscan does not find a d-link access point who is in the list of available w-lan devices of windows 8.1 this accespoint has probably a ip number in the segment "0" (windows browsers can not access devices in an other segment, but Windows shows w-lan devices in other segments as available).
best regards
