ya 10147 is giving me WiFi issues too, it periodically does not want to connect to my 5GHz, says wrong password when I know its correct. I removed the 2.4GHz auto connect and a reboot usually fixes the issue. Been having this issue since 10130 or 10135... Since I went through 7 SP3s before I got one that would connect to WIFI longer than a couple minutes this isn't a huge deal to me.
