Please, some information about the wireless adapter in the client (laptop?) you'd like to use for game playing.
And information about the wireless router you're connecting to.
Is QOS in use on the router? Anything else the router is being used for? I assume that this is a shared router between you and your roommate.
You may want to get an external USB wireless adapter to get more speed, if you can get more speed *smile*. But that remains to be seen...depends on the hardware that you currently have and have access to.
