Unhappy Sirius Port Numbers

Im having trouble streaming sirius over the net with my router. I get a rebuffer approximatly every 90 seconds or so. Ive traced the problem to my firewall (i think) and I believe I need to open up the ports to stream properely. I called sirius but the lady i talked to didnt even know what a port number was. Any help is very much appreciated.

If you are using the default firewall/router settings, then you shouldn't have to open any ports and it may sound more like it's a network congestion/ latency problem (since you were able to make a connection and listen for a while).

I use a Linksys with encryption and MAC filtering and didn't have to open any ports.

If you are restricting outound traffic on your router, then you may need to open some ports. I don't know what they are though. But I'm sure someone here knows.

Good luck.

Mark.

thanks for the info Mark. Im pretty sure its not network congestion because if I bypass my router (ie. plug internet directly to computer from modem) the problem goes away. Im using a Belkin router, anyone have any thoughts?

If your router has a stateful firewall, then the problem might in fact be the firewall. Part of the way Sirius secures their stream is that port numbers change periodically. If your firewall has timed out the session before Sirius changes ports, then you may lose the stream. When you lose the stream, you will have to reinitialize the outbound request with authentication to reestablish the session and reopen temporary ports in your firewall. Sorry if this is confusing, but firewalls should handle this in the background. Two suggestions: (1) see if there is updated software for your firewall. If so, download and install it. (2) if your firewall has some kind of session timeout setting, make it longer. Longer sessions will make your firewall slightly less secure, but will probably increase the reliability of the Sirius streams.

Rock on!
