Netgear Discovery tool 2.0.7.0 no longer finding my 5 switches.
I have used the utility many times before. Sometimes I have to run it twice to get results. Now it doesn't find anything. I can ping them all by IP, I can get into them via web and they are all...

Another thing you might try is connecting the PC with ethernet instead of WiFi.
The discovery method uses a broadcast protocol, and sometimes the router doesn't forward the broadcast packets across different network segments (e.g., wifi <-> ethernet).
Power-cycling the switches is another thing you might try.

Afraid, this is wrong, appears you still think in the old NSDP ways... (Wiki:
Netgear Switch Discovery Protocol ).
NDT is making use of SSDP, which is based on (Wiki:
Simple Service Discovery Protocol ), multicast addressing to a specifically designated IP multicast address at UDP port number 1900. In IPv4, the multicast address is 239.255.255.250, and SSDP over IPv6 uses the address set ff0x::c for all scope ranges indicated by x.
