speed change

So I guess it was like Wednesday or Thursday 30th or 31st I think of July 2024. So normally my internet is around 30 MB download with a upload between 5 and 10 MB. So Wednesday or Thursday of July 2024 at the end of the month My download speed was anywhere from a 100 to 120 megabytes per second with an upload of less than one megabyte. It was like this most of the night I couldn't do anything because my upload speed was not fast enough for anything but my download speed was super awesome. Why is it I can get these speeds on a random case but I can't get them constant. No it's not because of working on towers I drove to the two towers I'm nearby and I went to the one furthest away first and nobody was there and then I drove to the other one and nobody was there that's the one I'm pulling off of it's less than two miles away well right out two miles away. Don't know why you can have such a fast download speed Just out of the blue and it no it wasn't because it's congested I've done talk to people online through service. This was up an evening when usually my speed is around 30 anyway but my upload is good enough to do anything. Wondering how all this comes into play of you can have some of the blazing fast that would be blazing fast for me Internet speeds versus you can't do squat diddley. No one seems to have an answer or don't give a crap. Overthrow at random answers just to get you off their phone. I'm now back to slow speeds and my upload speed doesn't seem to be anything at all. I do appreciate T-Mobile because they're the only ones that's actually survived me from going nuts by having internet out this way I could go with the v word but I do not like them do not care for them. And they do not have home internet. I'm just on the edge of the pie but when I can receive anywhere from 100 to 120 constantly for an hour or two that tells me I'm okay of getting those speeds but for some reason I don't.
