So I need help with this problem. I am on BSNL night unlimited(2-8 am free) connection which I connect to using a TP-link TD-w8951nd modem router. My question is - if I turn off my computer, does the internet connection automatically diconnects or not? I use night time for heavy downloading and don't want to be to be hit with massive bills. I could use the bridge mode of modem to connect to internet but it is very very sluggish and some sites fail to load on that mode.
