I have a laptop which resides in the main router (a Telekom Speedport) WiFi subnet 192.168.2.0 and another desktop machine sitting in a different subnet 192.168.90.0, that is created by a switch plugged into the Speedport.
Their respective gateways are 192.168.2.254 and 192.168.90.254, both bear the submask 255.255.255.0, indicating that they do not consider each other local.

Speedport - Wifi (192.168.2.0) - Host 1
|
Switch - Subnet (192.168.90.0) - Host 2
Is it possible to configure the routing on the Windows hosts that they can see each other by hostname or IP and exchange files or is that something I need to change in the Speedport router (or the switch or both) ? I tried setting the submask manually (to 255.255.0.0) for both hosts in their connection managers, but after that no internet connection worked at all.
Where do I need to change the configuration?
1A switch does not create a new subnet. It’s not clear how your network is functioning. Please be more specific. – Appleoddity – 2019-10-31T01:12:22.107
Their respective gateways are 192.168.2.254 and 192.168.90.254 Both these addresses are Speedport's LAN addresses, is it? So Speedport must route traffic from one of local subnets to another - set this. None client settings may help in this case. – Akina – 2019-10-31T05:24:52.203
