First of all, you should check whether your internet access is not too slow itself. Compare the indicated speed of your internet contract with the result of an internet speed test. If your contract is older, compare your contract with newly available contracts on the website of your internet service provider. Maybe you can find a faster and cheaper contract.
You can use a speed test e.g. at www.speedtest.net, if you have an Ethernet cable available, use it to connect the router to your computer. In the case of using Wifi, please place your computer as close as possible to the router to minimize possible interference.
What can you do if the result of the speed test deviates significantly from the specified speed of your contract?
