Wireless is not very reliable. Even in my home just simply pinging www.tm.net.my , for wired my ping is consistently 18-21ms. Then once I change to wireless N, the ping fluctuates from 25-90ms. Not noticable for web surfing, but less reliable for online gaming. Sometimes it would lag for no appratent reason, only solution is to reset the whole wireless part of the router, then it'll back to normal.
