We have data hosted on a PC which is accessed by 5 different PC's - 2 are wired into the network and connect fine, 2 only work with a wifi connection (Can't connect through ethernet) and 1 can only connect by both but drops the ethernet connection randomly. The latter needs to be a wired connection as its out of the WiFi range.

Internet is accessible on all machines through both WiFi and Ethernet, all running windows 10, all network drivers are up to date, network sharing settings are open and I've even tried disabling the firewalls but to no avail.
