Does anyone know how to improve internet service?

I have 1mb of internet and it comes the update of 2.6 And probably will have 1 or 2 weeks with the computer on 24/7 Only downloading the update, and I will not be able to do anything else with the computer or the internet, So if there is any way to improve speed even if it is 5%

To be fair, other than getting your computer to a friends house to download it (fast connection should do it in less than an hour), there isn’t much to be done. I am sorry.

Contact your ISP and ask if they offer higher bandwidth packages.
