I have been using Parallels with W10 on my mac for quite a while. for some reason, in the last two weeks, the network adaptor can no longer see the available networks, and the only way i was able to connect was to manually configure the IP address to match the router. when i move to another network, there is no connection (even though i remove the ip configuration). it appears that DHCP has stopped working or something is preventing the wireless networks from being seen.
