Slow internet speed and downloads since power outage

My download and internet speeds slowed down after a power outage last month. Prior to that, it was great. I have plenty of data left, yet my wifi is very slow. What should I do?

I think where we should start to root cause this is by running a speedtest as it will give us speed from your device as well as speed from the modem. You can follow instructions here: How to run a speed test from my modem?.

If you have a problem with doing all that let me know and we can take a different approach.
