Do you guys know any solution, I will be so grateful if someone can help me fix this pain in the butt PB problem.

What's your internet speed? you don't know try ]Speed Test and tell us, you could also be having some line problems? ever tried contacting your ISP to ask them to check your line? They "should" do it for free depending on who you're with (at least it's free in the UK)
