Connection type. WiFi is usually slower than a wired connection. Using an Ethernet cable to connect your laptop or desktop can increase your speeds.
WiFi equipment placement. Put your gateway or wireless router in a central location, out in the open. Avoid file cabinets, closets, and spots that may get covered (by coats, laptop bags, or equipment, for instance.)
Device limitations. Maximum WiFi speeds could be limited by factors such as number of devices on your network, your device's age, limitations, and model.
Older versions. For the best results, make sure Internet browsers and operating systems are the most recent versions. Also check that you have an up-to-date modem.
Open programs. Close apps and programs that use a lot of data as well as any downloads in progress that may impact results.
