I have an old Sony Vaio Desktop Computer, the VGC RB-42G that has the Intel® PRO/100 VE Network Card. My incoming internet speed (wired download speed) is at 238mps, but it wont reach near that on this computer. Is that because my network card is limited to 100mps (is it?)? So, can I just go out or order a new card that can handle that incoming speed so I can use what I pay for, or is that not possible with the age of the computer & components, and I need to bite the bullet and get a new computer? My modem/router are up to date & fine. Thanks.
