hi coldcell
welcome to the forum
seems like you have a pretty OKAY PC and your connection seems fine too
well the speed maybe not the Latency
latency is what causes lag, and here are a few things u could do to spot latency issues
i don't know how WoW works, so i don't know if u could do a tracert to their server
but i am sure they have 100's of servers so u wont be able to
try doing a tracert to testmy.net
click on start > Run > type cmd and press OK
a window will open and then type tracert
www.testmy.netonce that has finished u could also try typing ping -t
www.testmy.netlet it got for a few seconds and then press CTRL + C to stop it
copy the results and paste them here also
the issue is not that you don't have enough bandwidth
please post ur results here
