It is confirmed, my router is defective. The computer technician confirmed today that the router is defective and they are returning it to the supplier for a replacement. I shall have to wait from three to four weeks before I can have the new replacement. Well, I am glad it acted within the warranty period otherwise I would have bought a new one. So for now, I shall have to maybe buy or borrow a switch hub so that I can use internet for my lappy when at home. My sons will have much time to play their favorite computer games once I get to use my laptop.
