Yup, I worked tech support at an ISP back when NIC drivers could be a PITA. There was a phenomenon I called 'first blamer advantage', whoever the customer called first whether it be the NIC maker, Microsoft, their ISP would blame their problems on someone else and the customer would think whoever was blamed was at fault. Usually we'd blame the NIC company, and then offer to send a tech out to fix the problem we blamed on them as a courtesy which made the customers accept the ridiculously long time it took to get a tech out.
