Yes it can, but like I said in my earlier posts that if you have TP-Link Modem + Router which includes Bandwidth Control Feature than consider your problem resolved. Other than that if you are willing to use a software than my dear bro there are many out there, but majority will only work if you have a setup of Server Client Model. In which your Main PC or Laptop would be the server through which you can provide Internet and Local Connectivity and you have to your PC or Laptop turned 24/7 so that others can use Internet since your System will be the server. So I would suggest you to sell your old Modem + Router and get a TP-Link Modem + Router from the market, but before buying kindly search that precise model and then go to the market to buy it.
