I recently switched from TWC internet to CenturyLink's 100 mbps fiber service which is new to my area. I also now have their Prism TV service. Since it was installed, the max speed that we have gotten via wifi is 35 mbps and this was when I was sitting directly in front of the router/modem. The equipment that was given to us is the Technicolor C2000T. When I connect directly to the modem, I get 100 mbps. Any ideas what the problem might be? They have already switched out my modem once. I have also checked for firmware updates and changed the channel that it was originally on.
