Wait for about 30 seconds, plug the modem back in first, and once it is connected, plug your router back in. This can refresh your network and often resolves issues with speed.
• Check for Router Firmware Updates: Outdated firmware can lead to performance issues. Check your router’s manufacturer’s website or app for any updates. If available, install any required firmware updates following the instructions that were provided with your router.
• Router Placement: Place your router in a central location, away from walls, metal objects, and other sources of interference. Elevating the router can improve signal quality. Try to place your router away from dense walls, thick furniture, and appliances which can cause interference.
• WiFi Channel Congestion: Use a WiFi analyzer app to check for channel congestion. Switch to a less crowded channel in your router settings. If you live in an area with many WiFi networks, there may be multiple networks using the same channels. Use a network analyzer app to determine the best channel for your home.
• Check Your Equipment: Ensure your router and modem are up to date. Older equipment may not be able to handle modern internet speeds. Consider upgrading to newer and more capable equipment for better performance.
• Contact Your ISP: If the problem persists, contact your ISP to verify if there are any issues on their end or if you need to upgrade your plan. They can sometimes also offer a better assessment or suggest alternative solutions.
• Limit Device Connections: Too many devices simultaneously using the internet can slow down speeds. Reduce device connections during heavy bandwidth usage. Disconnect devices that do not need to be connected at that time.
• Use Ethernet Connection: For devices that require a stable and fast connection, use an Ethernet cable directly connected to your router instead of WiFi. Wired connections are generally faster and more reliable than WiFi connections.
• Consider WiFi Extenders: If you have a large house, consider using WiFi extenders to improve signal coverage in weaker areas. This will expand the effective range of your WiFi network, and help eliminate dead spots.
• Adjust Quality of Service (QoS): Access your router settings and check for Quality of Service settings, which allow you to prioritize certain devices or types of traffic (such as streaming, gaming, or video calls). Prioritizing devices for a higher level of bandwidth can ensure a better experience for those devices.
