Great connection, frequent disconnects

Hi all,

I am troubleshooting an xbox live connection issue I'm seeing while playing certain games.  I started with a wireless network setup, but am reproducing the problem readily now with the xbox connected directly to the modem, so I'm confident this does not concern the router or router settings.

I have a Toshiba PCX2600 cable modem, connected with a medium-sized cable (10-15ft I would guess).  When the router was connected, I was getting speedtest results on my laptop of ~15Mbps down / ~1.5Mbps up.

Currently, I am only experiencing the issue playing Halo Reach, specifically when trying to play custom games with other players.  I can play matchmaking with minimal issues, only actually dropping every now and then, but when I try to join a custom game party, I seem to only ever last 1 or 2 games before dropping.  Often I am dropped while transitioning between the lobby and game-start the very first game after joining a custom game party (please note I am not referring to an actual Xbox Live 'party').  The in-game network checks show green (optimal) across the board.

Other game modes, other games, other forms of network connection (laptop, phone, etc.) do not seem to have similar problems.

What Country/State/Province do you live in?   USA / VA
Modem brand & model number:   Toshiba PCX2600
Router brand & model number:  Xbox connected directly to modem
Network Connection Type:   Wired
Things you have tried: 
Is UPnP Enabled?  N/A
Is NAT Type Open?  N/A
Any Error Codes you encounter:  no
What type of internet do you have?  Cable 
Who is your ISP(Internet Service Provider)?  Cox
When you run "Test Xbox LIVE connection" what is the exact message shown on screen?  Connected

I have Halo Reach installed on the hard drive, and am running from that, so I assume that rules out the possibility of the problem being the game media (I have deleted and re-installed it, experiencing the connection problems both before and after).  Is that assumption correct?  The next thing I want to try is a newer Xbox (I have one of the launch models).  I will request a friend's help in this, but wanted to post here in the meantime.  Any ideas?

Thanks,

-Beav

That brand of modem is outdated by four years (atleast it is through TWC). I used to have the same one though Time Warner Cable until February of this year. They replaced it for free with a smaller newer modem. I would check with your cable provider and see if they have a new modem available for trade in especially if you have had yours for more than a few years.

 

It definitely sounds like an issue with your modem. Everything else you have listed seems to be in order.

If the disconnect takes down your entire network, then it sounds like your modem is faulty based on your statement above.  I'm not sure why you see it mostly with Reach unless the amount of traffic is overwhelming the modem to the point of it hanging.  I'm not sure how easy it is to replace your cable modem as your ISP authenticates with the modem's MAC address if I remember correctly but it seems the likely source of your problems.

Some updated information...

I tested with a friend's Reach disc, but the error still occurred.  I tested with a friend's Xbox 360 (a newer one w HDMI port), but the error still occurred.  All the while, I was playing with my Xbox directly connected to the cable modem.  Each test, I got disconnected from Xbox live after about 5 games.  When the disconnections happened, my entire internet connection would go down, meaning I'd have to reboot the cable modem.

As I mentioned in the OP, the in-game network checks in Halo Reach all indicate optimal status (green), including the NAT indicator which reads 'Open'.

Sorry, I don't mean to second-guess your answers, but everything I have read indicates that NAT settings only apply to router usage.  If I am not using a router, isn't that the equivalent of an open NAT?  I don't understand how the host NAT settings (which I confirmed to be Open by the way) could affect me in this case.

Anyway, basically the only thing I can think of to try that I haven't already, is using a different cable modem.  I am reluctant to buy one however because the problems seem limited to Halo Reach custom games.

Yes, it all has to do with how the packets of information is routed into the person hosting.  Distance also plays a part.  There are many things to consider but I know Reach has some networking reports you may check in one of the menu options.

Thanks for the replies.  What I don't understand is, why they can go about hosting custom games with the general public (meaning lots of non-friends joining) with no problem, but I specifically cannot connect to them every time.  To me, that seems to indicate the problem is likely on my side, but of course I base that on absolutely nothing :).  When I am not using a router, can their NAT settings affect my ability to connect?

Thank you Knowitall, I kept trying to respond but could not get the reply box to appear in firefox so I switched to IE after seeing your reply.  I too agree that the host or other members of the custom game could have a NAT that is not open or could have a very poor connection causing the issue.

I'm by no means a network or connection expert but I see no one has answered you yet.

I can tell you that it doesn't appear that it is a problem with your U/L and D/L speed as those are adequate.  

I have seen and heard about this issue pertaining specifically to the "Custom Game" modes and affecting quite a few people which makes me wonder if it has to do more with inadequate internet speeds or NAT issues with the individual hosting the custom game.

What do you think, could this have anything to do with the issue?
