A friend of mine is asking for help on why his wireless connection on his iMac PPC powered desktop is slower compared to two Windows machines 6 ft away that operate on wireless. I don't know how much RAM he has but the only thing I know that might help is if his version of Tiger is older than 10.4.8. If so, I will update him to the latest version. Any suggestions on how make his wireless connection faster would be appreciated. I am going to try some of the solutions posted at: http://www.macfixit.com/article.php?story=2005093011343164 I will let you know if any of these create a solution. Will adding more RAM to a 2.1GHz PowerPC G5 (iMac) that currently has 512MB RAM help with internet speed?
