Unable to write network settings to device

Hello,

I keep trying to set up a home network. I get all the way through the "setting up a wireless router and access point", but my computer will not copy to my flash drive. It comes up with the error: "Unable to write network settings to device" (but doesn't give me a reason why).

I reformatted the flash drive and also used a different one, but to no avail. Neither worked.

I've tried to find information on the Windows website, but there is nothing about this.

Please help!
