What exactly
did they tell you? Did they offer
any solutions? What exactly did they have you try?
1. Go to
Speedtest.net. Test at the location nearest you and a location very far from you. Post the results from both tests here. Each test completes and gives you a picture link, post that here. The next time you experience a latency problem, immediately perform speed tests to the same locations and post those too.
2. Need to know a lot more about your computer. What OS? Full hardware specs, router/modem specs, games you're having trouble with, ISP company... the more you provide the easier it is to help.
