Hello All, Trying to connect my old Dell Dimension E521 to the internet (Optimum Altice) using a wireless signal detector ( A dual band usb adapter) 600 mbps, usb 2.0 speed. The problem i am running into is that the antennae is picking up my router signal, but when it comes to entering my password it is not letting me in. My password is correct, still no dice...can someone please help me out? Thanks in advance
