I have a Netgear ( i believe) Wireless router/modem combination that works fine for the most part. I beleive the type of security that I'm using is WPA. Anyway, my roomates computer won't connect to the wireless internet, which is problem number one but I think it may be due more to his older computer. The main issue is that since he cannot connect to the wireless internet, he has to plug his computer in to the modem/router via ethernet cable. When he does this, nobody else can access the wireless internet. Can somebody tell me WHY this is and HOW can I FIX IT???? It is driving me friggin nuts!!!!!!!!!!!
