Hello, all! For the past day, my internet speed has been fluctuating a LOT. I've done speed tests on multiple speed checkers, and for a LONG time, my download speed has been at a consistent 50Mbps. However, now it fluctuates randomly from 50 to 20, occasionally going down to 0.5 Mbps. I'm A+ certified, so I'm fairly sure I'm not just being an idiot, and I've checked my modem settings and no unauthorized devices are on my network. The fluctuation seems very random, and I've done the speed testing on multiple servers. I've released and renewed my DHCP IP address, and I've done the basic unplugging and replugging. My computer, where I performed the speedtest, is connected via Ethernet.
I am a content producer, so this is semi-urgent. Please provide any possible help, and I will supply any other information as needed. Thank you in advance!
PS: This probably is VERY random. I can do three speed tests in one minute, and I can get 50Mbps one go, 20Mbps another, and 0.5 for the last one, all within a minute.
