I tried an ethernet cable (I don't know what type or cat) from my laptop to the router. Earlier I did a Google speed test and got 60mbps. I did one about 2 hours ago and it went at 4mbps. Upload speed is going around the 40mbps advertised speed. I notice the download and upload speeds do fluctuate. The speed isn't constant like my previous plan which I think was FTTC 100mbps plan.
