I have the iPod Touch 2G with 2.1.1 installed. I noticed this problem about 5 days ago and I do not know what has caused it or how to correct it, so thanks for any help that I get. I can best describe it as a temporary failure of WiFi. I experience the following problems: 1) After using AIM for a couple of minutes, I stop receiving instant messages despite the fact that my friends are still sending me instant messages. I am still able to send them and everything works fine for a few minutes in to the conversations. But after the client has been open for a few minutes, I run into these problems. If I close the AIM app and reopen it, I get all the messages that I failed to receive due to lag, and it I receive new messages for another 2 or so minutes before it stops receiving them again. 2) After selecting a YouTube video, it will load approximately 30%-50% of the video at an acceptable speed, then stop loading all together. This happens no matter how many times I view a video, and it happens with all videos. 3) Applications will stop downloading before they are finish and prompt me with an error that the iTunes store is unavailable. After retrying the download a few times, it works. I do not think I have made any changes to my iPod or to my router, so I have no idea what is causing this, but it is very frustrating. I would appreciate help. Thanks in advance!
