Hello and welcome to the forum! You need to provide more information: 1) What MBPro (year) do you own; 2) What OS X is installed; 3) What other devices are you talking about; 4) How do you know that your DL/UL speeds are 'significantly' affected (assume that you are testing from a site such as Speedtest Net); and 5) Who is your ISP and what type of router are you using?
