Try these steps.
1. Turn off all the devices in the chain in this order: MBPr, any wireless routers on the network, the internet modem.
2. Wait several seconds after turning off the last item then power them back on in reverse order waiting for each device to completely power up before turning on the next device.
Let us know how it works.

Greatly appreciate the help, but that didn't work either. I ended up deleteing my library and re-installing from a Time Machine backup. Now idea how that could've fixed it but it did. At least everything is back to normal now.

That's a bit of a extreme solution but I'm glad you got it sorted out.
