I need to follow the search plan step by step. I'll start with Round One operations. search results provide information on the error. Some results explain the first octet restriction (must be 02, 06, 0A, 0E). Others mention driver limitations and Intel wireless cards having hardcoded MAC addresses. I need to open some of these results to gather more detailed information. I'll open result 0 from the first search, result 2 from the second search, result 1 from the third search, result 0 from the fourth search, result 2 from the fifth search, result 0 from the sixth search, result 0 from the seventh search, result 0 from the eighth search, result 0 from the ninth search, and result 0 from the tenth search. search results have provided a good amount of information.
