Thank you for submitting your recent request to Codemasters Customer Services concerning International Cricket 2010.
We are limited in what we can do to resolve your problem, as you connect to your fellow players when playing the game - not to a dedicated server.
We can, however, make some recommendations
- Ensure that you have the fastest connection available to you and that you have a good ISP that is close to a major internet backbone. ISP rating guides are quite common on the internet and in Magazines, so refer to these for more information.
- Contact your ISP to see if your connection is suitable for gaming and if they have an alternative connection point that they can offer, which is less likely to suffer from congestion.
- If you are using a (A)DSL connection, ask your ISP for the contention ratio that they apply (this will be the maximum number of users that share your bandwidth). A typical ratio is 50:1. Anything more than that may result in problems during peak hours
- Playing at times when fewer other users will be using the internet, if possible, will also reduce congestion problems (particularly if using (A)DSL for the reason above)
- Also ensure that you have the latest firmware installed for any routers/modems etc, particularly for wireless devices.
- Make sure if you are using a router or hardware firewall that all of the ports the game uses are opened/forwarded.
You should also choose the games with the lowest ping where this is displayed.
