I have been using the app Who's on my wifi.exe for many years on my PC with good success. I installed a new router (2.4G and 5G) and now a number of my cell phones are not being detected, even though they are on the network. Same result with another app (Wireless Network watcher). How do I get this to work properly? (I have switched between 2.4G and 5G, but still no luck.)
