Hi jlritten,
Since they are on diff subnets, your network devices won't be able to communicate.
To resolve this issue, your main router needs to be untouched in terms of router settings, the second router needs to have DHCP disabled and assign a Static IP within Router's A's DHCP range. More info. on how to do this by following John Will's guide here - Post# 5.
