Windows 8 64-Bit pc will not detect network on startup. Every time we have to do a "scan for hardware changes" in device manager. Otherwise it will not connect to network automatically. We did re-installed network driver, updated and checked same network with other PCs. But in other than windows 8, same network works fine. Only 64-bit Windows 8 is having this problem. We are using Intel DH61WWB3 Mother board with i5 processor.
