Network Problem after turning off "secure Host while booting"

Hi all…

I tried doing the secure host while booting thing last night. It took far to long this morning to boot so I unticked the box. It now boots back to normal but I notice that after about 1 minute of my computer having been completely loaded the wifi connection to my home gateway disconnects and I have to click “Repair” to reconnect to it. Why is this?

Also, when doing the Repair feature, CPF doesn’t let the repair clear DNS Cache.

Hope you all can help.
