My parents home network is fast, and one of the higher end offered by our cable company. There are a lot of devices on it. (Phones, Tv's, Cameras, Alexas etc..) When all is good I'll get a good download and upload speed test result. (ex. 350+Mbps download)... However, quite often it'll get really slow to about '25mbps' download speed. When this happens I reboot the router. I find myself doing it a few times a day. Is that normal?
