Hello Catherine,
Welcome to our community and thank you for your post. We were able to locate your account and do see that you had a case escalated to our advanced support department on 11/29, but have not been called. We've escalated this to their manager to see why you were not called.
In the meantime, however, I'd like to assist you in investigating and resolving your speed concerns. I was able to do a full run of diagnostics on your system and see that your dish's signal is great, the modem is communicating well with our network and the remote speed test run from our servers to your modem came back with a 16Mbps download speed.
I'd like to see if you are aware of any Peer to Peer file sharing, cloud services like iCloud or DropBox on your devices? If there are, we recommend taking a look and seeing if these are not set to manual download/upload settings. It is very possible something like this could be hogging up your bandwidth at home, especially with as many devices that are connected to your network. Are you only experiencing slow speeds on a single device, or across all of them? If it is a single device, have you checked that device to see if it has a VPN (virtual private network) setup on it? That can definitely cause slow speeds. Looking forward to digging in and finding the answers with you.
Thanks
Amanda
