I have lately noticed several 4000 Direcway/Hughes net internet systems for sale and If you check with the Tech Department at Hughesnet/Directway you will find that they do not activate any used system older than the 7000 modem. Buyers beware.                                On February 02,2008 I had to add the 6000 modem to the dead modem list. If you buy a used Hughes/Direcway internet system leave the 4000 and the 6000 alone unless of course you just want the dish and electronics. Just remember these older modems are no good so do not let anyone talk you into buying one. If you are interested in getting a used system to save by not having to go into a contract, and save a lot of money over the years. Buy a good used system, and with my self install CD you can install it anywhere you want to. If you already own a Hughes/Direcway internet system, with my information, install CD you can fine tune and even move your system from place to place.
