There are many ways to test your internet speed, however, we recommend using http://wtccommunicationsia.speedtestcustom.com. You will want to plug directly into the modem to do this speed test. You may also want to consider restarting your modem before taking the test. If you have a modem and a router, unplug the router from the modem and using a network cable, plug the computer directly into the modem's network port. It is recommended to do 3 or 4 tests and then average them to get a better idea of speed. It will be more accurate going directly through your modem because it has the least number of hops to go through. The more hops the bigger the chance for slower speeds. Still feel like your speeds are not keeping up? You may want consider upgrading your high speed internet plan.
