Cann't play WoW with high latency?
Forgot about IP hunting.... and no more back door to set your system registry please ...

Just follow below procedure
1. Call 100, tell the helpdesk said your network so slow, extreme high latency, you cann't do video streaming, you're NOT using P2P software and YOU CANN'T PLAY ONLINE GAME AT ALL !!! Request them to reset your port, and you had try all their standard operating procedure [i.e. flush your IE, direct connection, you had throw away your DSL spliter, turn off firewall, do antivirus scan.... all these crab blablabla].
2. The next day mid night, call 100 again, tell them it's midnight now, the traffic should be very smooth, but your latency still sky high, request them to send technician to check your network.
3. When the technician visit you, please don't tell them your network super lag or high latency ... B'COS THEY DON'T UNDERSTAND WHAT YOU MEAN, THEY MAY THINK YOU'RE TALKING ABOUT YOUR NETWORK BANDWIDTH OR SOMETHING ELSE, JUST TELL THEM NETWORK SLOW lol, ask them is there any 'Special port' available [they don't call it TM Direct port, they name it special port internally, only God knows why].
4. After that you know what you should do LOL ....

Plus : Don't waist your time to report to ACA, cus ACA staffs using that port to play WoW too, they understand your problem and feeling.
