Increment: the amount a network address goes up by i.e. increment of 0.0.4.0 192.165.0.0 ->192.165.3.255
increments are the amount the network decreases by each time, see week 6 notes
broadcast address= the network address + increment -0.0.0.1

to connect routers with DCE you need to use static, name the networks behind the other router, give the other router as the next hop, and then test
if a router won't connect to a subnet on another router after being told where to go with static, delete the static and remake it, you may have messed up the message
if a device doesn't ping outside its subnet without any reason not to, try replacing it entirely with a new device
the most difficult things for me were figuring out how to set up the trans-router pings, and when one device was unable to ping anything outside of accounting for some reason. The former I was able to resolve with time, YouTube videos, and patience. The later I was able to resolve by completely replacing the device in question. Some things I'll take with me from this lesson are to write down everything, find a better way to keep track of subnet masks, and to ping literally everything possible.
