I just recently purchased an Alienware 17 and have had issues with lag when playing BF3. Every so often my character will run in place briefly or won't respond to a button press causing me to have to hit the button a few times. However, it works fine when wired. I have tried it playing at my home and at a friends house and have had the same issue with lag. I ran a speed test and was getting 20mbps download and 5mbps upload with a ping of about 88 on average. Any ideas on what could be causing something like this?
