Mhm, if this a serious issue? If so it might be the IP you are using. IP’s have different connection depending where you live. If this is not a IP issue maybe restart your router. Hopefully it gets better though.
My internet is "unlimited" but that just means that after we use like 50 gigs they slow us down, so whenever there's a bunch of other people using the internet, it slows us down to basically dial up speeds....
