DG wroteDon't worry, you're not alone in this.
My line can be running fine in the morning and early afternoon (2 to 3 CRC errors per hour) when suddenly, as soon as it gets dark outside (around 4:30 / 5:00 pm), I start getting around 30 to 50 CRC errors per hour. This usually lasts till around 9:00 / 10:00 pm.
I don't know if the errors are due to problems/noise on the line due to people using lights and electric appliances (heaters, etc...) at night or if it's due to some kind of packet collision on Ogero's side because more people are home and online at night.
To be fair I'm quite confused as well. On some rare occasions (like once or twice a month), the connection would be fine even at night then boom once the electricity switches SNR goes SHIT.
