I am able to reconnect to the wireless network in a heartbeat, but sure enough after a few minutes of downloading a file, my connection just disconnects. If anybody has any answers it would be greatly appreciated. Also I am sorry if this is an easy fix and therefore a dumb question, don't mean to waste anybodys time; I have researched this a little bit, but can't seem to find anything.

Is this only happens when you are downloading through tixati or all the time?generally tixati has nothing to do with wireless connectivity issue. As I also use wifi and face no problem. It may happen if your router or your wireless device gets hot. Try connecting through lan and see what happens.If it disconnects then I think your ISP is disconnecting the connection. If nothing happens change your wireless device.
