I find the troubleshooting instructions very slim. What can I try beyond what tech helped me to set up and what is not suggested on the GL website?
Did you get your speed issue resolved?
Could you run a speed test from this site http://www.dslreports.com/speedtest and then share the results link?
That's an excellent idea and I'm sure that someone at Greenlight has already been thinking about this type of service. I think they are just trying to keep their operations as simple as possible so that they can focus their resources on growing their customer base without adding too much additional operational overhead.
My guess is that it's more complex than simply offering you an hourly rate for additional installation and setup services. They would also have to have additional staff to provide phone support in case something breaks sometime in the future. From my own personal experience people usually call the person or company that installed a particular item if problems show up later on.
If you tell me some more about your home network and what types of devices you'd like to setup then maybe I can be of some assistance. I offer computer and network consulting services in case you are still looking for some additional IT help.
