I have a HR44 and HR21. The 44 is in my house and the 21 is in my detached garage and workshop about 100 yards from my house, so I have a second dish on the garage. I understand the 17 uses WIFI to connect to the clients. Correct???? In my case WIFI will not reach into my 40x 60 metal garage. Any idea how ATT will handle this situation? I would just as soon keep the HR21.
