Comcast provided Cradlepoint is a performance bottleneck
We were provided a Cradlepoint wireless backup device as part of Connection Pro service by Comcast. It works well except for one major issue. We pay for 600mbps service and we get it when we are directly connected to the cable modem. But when connected through the Cradlepoint, we get about 100Mbps. 1/6th the speed we are paying for.
When I Googled a bit I found some other people were seeing the same issue. Cradlepoint also has a page that describes the issue here:
On that page, they say the cause is this:
"Certain features need to disable the router's hardware acceleration in order to work. When this happens, it results in decreased throughput performance."
Since Comcast does not allow customers access to the Cradlepoint configuration, we are at the mercy of Comcast techs to tell us what is going on here and if there is anyway this problem can be fixed.
If anybody has been able to figure this out, please share your solution.

Hello and Happy Tuesday, @portlander33 Thank you for reaching out to Comcast Business Support community, here.
Connection Pro kicks in with 4G LTE connectivity if you lose power or service, as a backup Internet connection. It helps keep your Internet up and running, but only as a backup. It is not designed to match your In office Internet Speed.
4G offers maximum real-world download speeds up to around 100Mbps.
I hope this helps.

"I hope this helps."
It does not. You misunderstood the original post. Connection Pro (Cradlepoint) limits the speed to about 100Mbps, even when it is not using the cellular network, but is using the cable modem for Internet connection. My Comcast cable modem is actively providing 600Mbps service to us. But Connection Pro can only use 1/6th of it.
If I disconnect the cable modem, Connection Pro kicks into cellular mode. In this mode, I only get about 2Mbps. This is fine. I have no issue with the backup cellular service being super slow. I have an issue with being limited to 100Mbps business service at all times, when I paying for 600Mbps.
Please see the link to Cradlepoint's site I provided in the original post. It clearly describes the problem I am seeing. I would look into this myself a little more, but I cannot. Comcast locks the configuration for the Cradlepoint device and customers cannot change or even view any settings.
