The first communication satellite was called “early bird” and it was lunched in the late 60s. This was a time of mainframes, token rings, and dumb terminals. The hub bent pipe technology has not changed much since then. There is this newer technology called “space-way”. It is a cellular switched on board the satellite technology that is compatible with 4G. It has mostly been used by the DoD for cruise missile systems. How ever now is going to be use for the air traffic control and will begin appearing on airlines as WiFi.
Because of the nature hubs there is a lot of traffic being broadcast. ALG Application Layer Gateway can resolve this problem through a routing table on the router that only lets traffic in for only those Application running on you computer the rest of the traffic is dropped. The Application Layer Gateway is part of the 802.11 n standard found on wireless N routers and will greatly improve a satellite connection.
Next the MTU, Maximum Transmit Unit, in this router must be statically set. The way the OS sets the MTU is through querying the DNS server. The satellite is a high latency connection and very thing is on hold until MTU is set. When the browser is stalled out and spinning it wheels this usually is the cause. If set in the in the router it is less than 1 ms for the OS to retrieve it. You set the number in the router it is between (1 – 1500). I start with 1492 then see if I have connection ping Google.com if I do. Then add 2(1494) and ping again until no connection. Then step down by 2 and that’s the satellite routers MTU.
Next it is good to use some other DNS, because the satellite providers DNS has the “DNS worm” in it. The Linksys Routers have three text fields for three DNS. You want to make sure you fill all three fields, because if you don’t the worm will write self back in and capture the router again. The worm will appear as the satellite providers DNS, a DNS cant write it self back into a blank field and then put it self back on top of the list. Only a worm can do that! I use Open DNS and Google DNS as the last DNS place holder.
If you have satellite most likely you have a rural electrical power company. The line need to be brushed out every few years, before this happen branches touch the line and the light dim. So it is good to have a UPS for the modem and router.
