Multiple network cards and access their networks

I have two network connections, Static IP Wired and DHCP Wireless. Wired is used for local LAN, it has an address range of 192.168.100.0/24 and a default gateway of 192.168.100.100. My IP is 192.168.100.200 The gateway leads to another network with address range of 10.1.1.0/24, which hosts some services used across the LAN. Under normal circumstances this connection doesn't have internet access.

Wireless connection has internet access, an adress range of 192.168.0.0/24 and a default gateway of 192.168.0.1.

I can have both connections turned on, but if I do, I cannot access services hosted on LAN. If I turn off Wireless connection, then Wired takes over and I can access LAN-hosted services, but consequently not the internet.

How do I configure Arch so that I can have both Wired and Wireless connections active with unrestricted access to both resources on the internet and in local LAN? I use NetworkManager but if NM doesn't allow such feat then I can set up any other network service supported in Arch.

Set static route to 10.1.1.0/24 via 192.168.100.100.

Abaddon is correct.  see man ip-route
