am on cheapest rate plan. Pretty sure its G3 Satellite. Will have to see If I can find my notes. The frequency helped a lot. Also go to tools internet options, connections, LAN settings, uncheck boxes in automatic and check in lower proxy settings.
You will also need to have someone good tune the dish with proper meter & get hooked on proper satellite. Even with this was still very slow until reset everything.
First try to shut off any virus software to see if it gets better. reset as above in IE tools then disconnect power cord to Modem, shut down system and wait at least a few minutes.
restart & retest. What type of connection quality are you getting?
