The trace route shows it timing out on the 4th hop.
After inputting a static route on the WAN router for it to go to the Cradlepoint E3000 Router (172.16.150.9), the trace route shows it starts at the interface IP (172.16.150.11), then goes to the Cradlepoint E3000 Router's IP, but times out from the 4th hop to the 8th hop, then resumes on the 9th hop.
When removing the static route of 172.16.150.9, there is no timeout, but computers get 1Mbps speeds, which is our WAN circuit speeds.
Also, a speed test ran from the Cradlepoint's NetCloud Manager resulted in over 100Mbps speeds.
Here's a screenshot:
