A sudden extreme slowdown in your internet speed can be attributed to several factors. It's important to first check if the slowdown is affecting all devices or just one; if it's just one, the issue might be with the device itself. If all devices are affected, potential reasons include network congestion, a problem with your ISP, or a router issue. Start by rebooting your router and modem. If that doesn't help, run a speed test and contact your ISP for further assistance. They can confirm if it's a broader service issue or something specific to your connection.
