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.
