I have 2 laptops both running Win 10 ver 1803, both connected to the same WiFi network, and belong to the same Workgroup. I'd like to be able to open either computer and see the other computer listed under Network, so that I can sync my data files. I have tried with Microsoft Defender on and off, tried every setting adjustment suggested by any online forum I can find, tried adjusting the Hosts file, tried syncing via portable hotspot, but I just cannot get the 2 computers to see each other. The only way I've found to sync the files (privately with out using an online storage service) is to use a third party software and a USB memory stick. Is it possible my router or service provider is somehow interfering? Just looking for easy way to sync 2 computers??????
