Upload speed issues

Don't know if it's the area, and after having a tech out it doesn't seem to be a problem with my equipment. My upload speeds have been garbage. I'm suppose to have a consistent 100mb, but constant testing has shown that it's dropping as low as 5mb. This is been happening for a bit now and I'm on the old black modem/router. Is this an area problem in NLV or is it a mee problem. If you want me to test under something specific lemme know and I can send screens.

If I try to check if there's an outage on the outage map specifically on the main website, the map just straight out doesn't load anymore. This problem is straight up invisible until I do something like streaming to a platform like twitch or run speed tests.
