It seems like these two entities have a major built in conflict. While I ran across many problems people had with the PS3 and comcast's HSI I never came across one like mine. When I plug the ethernet cable directly to the PS3 from the cable modem, I get nothing, not even an IP address. Meanwhile when I plug it into my laptop I get service no problem. Today I got a router and finally got that working after fighting with Comcast's activation (which was already done when I installed the service a couple of days ago but thats neither here nor there). With both wireless and wired connections to the PS3 the connection test gets an IP address then immediately fails the internet connection test. However, I can zoom along the internet just fine on the PS3's browser but I cannot for the life of me sign into the PSN! This is a very weird problem and if anyone can help I would very much appreciate it. :)

I need router brand a serial number.
 
I use Comcast through wireless on my PS3, and besides losing the connection, getting signed out of PSN, and throttling upload speeds it works great!
 
Zero problems with Comcast cable high speed here in Vermont, also have played online via comcast from Massholechussetts without issue.

I shut the cable modem off, disconnect line from computer, turn modem on, wait for lights to stabilize, plug into PS3, turn on PS3, play online.

I still hate the bastards, however.

This is known as the power down, power up fix. Often a network reset will not get detected by your modem or router and so it starts having connection issues. Simply reseting your modem and router will allow it to connect with whatever changes may have occurred, problem fixed. It can also sometimes be a case where your router itself has had a hiccup after running for a while or something and by resetting it you restabilize your own network.

Anyway, at the end of the day, if you have a normally fine network giving you connection issues the most likely fix will be to power down everything, then power them back up in this order: modem (let it fully connect) > router (let it fully connect) > interface device (PS3, PC, etc).

We are talking less than two minutes to fix and most people start calling their ISP upset.

This has actually gotten so bad that my brother's cable company has ads on TV telling people to try this before making any calls.
 
What I find interesting is that he can connect and surf the web, just not connect to the PSN. How would that be possible?

Different ports. Just because port 80 is open for http doesn't mean the ports are open for the PSN.

I'm not sure how accurate they are, but here is a list of ports the PS3 uses for various tasks.

Actually, that is why I want to see his router brand and model, because certain routers are picky about things like ports and various other settings.

I had the same issue with my Linksys router until I set up port-forwarding and made a few other changes.
 
I fixed it. My suspension of splitting a cable outlet for one digital box and one cable modem would not work was correct. I connected the modem to an outlet in another room but once I get a roommate I will probably have to split it again so maybe if I get a splitter that's 2 way capable it will work! You would think an installation guy would know this stuff.
