Low International speed problem is on Excitel copper connection, I have a 100Mbps plan, I don't know about the Fiber speed test, Excitel shows in the dashboard that you have fiber in your locality but the LCO says you don't have fiber in your locality, I wish I had their fiber because the internet gets disconnected while sudden rain or storm or even rise in temperature. 7 out of 10 times when net stops, first I raise a ticket and when the problem is not get resolved within 1 or 2 hours then I go on the rooftop and restart the ISP switch and the Internet starts working, and happy ending.
