1. Test a different modem/router The biggest cause of slowed down internet is a bad modem. Make sure your modem is suited to the internet plan that you are on. 2. Scan for viruses Sometimes viruses can live on your computer and suck resources away from what you are doing thus slowing down your speeds. Make sure that no virus itself is causing you to slow down. 3. Check your filters If you have your internet connected to a phone line that also has a telephone on it then you will need to make sure you have good quality filters installed on your line. These are little plugs that you attach to the phone line and they help filter out the disturbances. If you have ADSL2+ or cable make sure you have the appropriate filter. 4. Shorten and replace cables The length of your cables and their structure can affect speeds. Try replacing old phone cables, sockets and lines and instead use shorter and newer ones. This can often make a big difference. 5. Update firmware and software regularly Your router/modem has it’s own software that you need to update regularly. You can login to your modem by following your brand’s instructions. You also need to consider updating your computer’s desktop version, operating system, etc. as often the wireless settings become less compatible over time. I hope this will help. Cheers!
