Service performance declines gradually.
Service performance declines gradually.
Hello, I recently acquired a deco M4 router and have faced several issues over the past few months. The network has experienced intermittent red lights, random disconnections, and slow performance across all devices. On both Ethernet and Wi-Fi connections, users encounter frequent internet outages and significant delays when navigating websites or searching for content. Sometimes the system freezes for up to 30 seconds before resuming, followed by a sudden surge of activity. We’ve even had to turn off devices at night just to watch TV. Despite trying various troubleshooting steps—resetting the router, adjusting settings in the app, optimizing network performance, and enabling Quality of Service—I haven’t seen any improvement. I also removed about half of my devices that were functioning well. It’s been a frustrating three years dealing with these problems. Do you have any suggestions or solutions that might help?
I mentioned changing routers a couple of months ago, yet at the end it's been happening for three years now. Has this issue stayed the same across all my routers? What type of connection are you using—cable, DSL, or fiber? Are the modems supplied by the company, or do you have the chance to use your own? If they're spread across several devices, am I certain it's not the modem itself? Is this a recurring problem or just occurs when loading heavy data? It might point to overheating. Over the years, I've installed fans and heatsinks on both my modems and routers because I noticed performance drops during long downloads. Keeping them cool prevents slowdowns. Have you asked your service provider to investigate this? Regarding signal quality, I know it from my cable modem's interface.
As OhioYJ mentioned, did this problem occur before you installed the deco M4? If you switched your router and still face the same issue, consider these two possibilities: 1. Your ISP modem is the cause 2. A device or cable on your network is responsible (such as a TV, Wi-Fi repeater, powerline adapter, or faulty network cable). Since it’s simpler to check your own setup, start fresh. Connect only from the ISP modem to your M4 router using a new cable. Set up a new Wi-Fi name and connect just one device. Perform speed tests, verify everything works, then gradually add more devices (wired or wireless) back until the issue reappears.
I had another consideration... recently I faced a problem that I assumed was my new router. It turned out to be a faulty cable. At first, I didn't realize it since I was replacing a different router while using another cable, which was simpler (sometimes cable management is tricky). I believed the cable was fine and even passed a test after making changes. After swapping the bad cable, my full speed returned.
