Diagnosing Internet Issues - Shaw Blue Curve
Hello everyone. I’m using the Shaw 600 Internet package in Western Canada, but I’ve been experiencing significantly slower download speeds lately. Even a short 5-minute video now needs several pauses to load. The advertised speed is 600 Mbps, yet under typical conditions it feels like only about 1% to 10% of that. This has affected my gaming experience and prevented me from watching videos. I’ve reached out to Shaw’s technical support and ISP, but they can’t pinpoint the issue beyond confirming the signal strength in my building is strong. Their setup uses coaxial cables from the wall, so I was told to try a different one—though I changed nothing. A full factory reset of the modem didn’t help. They suggested checking for nearby coaxial splitters, but in an apartment, those components are hard to access. My power distribution box is sealed, and I can only adjust it by flipping breakers. When testing speeds with a wired PC or Wi-Fi device, downloads have dropped to as low as 2 Mbps, though they hover around 20–30 Mbps otherwise. Applying stress, like during a game update, still yields similar results. Interestingly, Task Manager shows much higher speeds (80–120 Mbps), but that seems inconsistent with actual performance. I’m wondering if anyone else has encountered this problem and might have tips to restore normal speeds. Modem model: Technicolor CGM4140COM ISP: Shaw Communications Subscription: Blue Curve 600 Mbps
It's just three months old, and the only option is to send it by mail since it seems too risky to visit a store and replace it amidst the pandemic.
They actually sent me a modem a while back, and surprisingly it wasn’t the problem. As soon as we connected the new modem, Shaw guided us through the setup process, but the issue kept happening. They scheduled a technician to visit, and the day before the appointment, our internet suddenly improved to normal speeds. I’m not sure what caused the week-long disruption, but it worked perfectly once the tech arrived.
It's been functioning well for over five years. Possible cause could be RF interference from the coax. This occurs when TV OTA signals, cellular signals, and other transmissions interfere with the cable system. Likely a faulty connector or damaged coax cable in the setup. Shaw identified the issue and resolved it. That’s my theory.
