Way back, when I was still a noob, I "modified" our family pc: 1.8Ghz dual core and 1Gb RAM and who knows what sorry excuse I had for a GPU that I got second hand for dirt cheap. I was super excited to lan some CoD with my best friend. So I went to the flea market, got a ethernet cable and plugged in. After struggling for 2-3 hours we finally figured out that I had bought the wrong cable. It turns out I bought a telephone cable. No lan for us! D: Next weekend, back to the flea market bought a proper lan cable, get home, struggle for another 2 hours. This time it turns out I bought what I though was the proper cable. It had the same head, RJ45 size but was missing the connectors. UTTER DISSAPOINTMENT!
Last attempt: This time I went to a real store and double checked I bought the proper cable AND got it at less than half price. Now I get home let mu friend know he can come over. He tells me he's not coming because of what happened. I had no choice but to gate crash his home. In the end, we played CoD till 4am.
