How about some more info? is it a syslink router, or Linksys? I have never seen a T-mobile syslink router (nor can I find any info on it) and what model number & revision is it? What model receiver are you trying to use, what is the currently running software version? If it's a ViP series receiver, are you trying to use the Ethernet, or telephone port? The more specific you are about your problem the more likely it is that someone will be able to help you. (Note: Do NOT post identifiable info such as Smart card/Receiver/Serial #s, as they won't be of any use to us)
