Wifi Not Automatically Connecting

Hi,
I recently installed windows10 pro 64-bit edition on my wifes laptop (legally) with authentic key. I've already updated the driver for her wifi adapter, upon startup most of the time it fails to automatically connect to our wifi signal. When it does it shows the the signal strength as excellent, the last thing I did was to 'forget' the connection & then reconnect to it again. I restarted her laptop & at least that time it connected correctly. I've been reading that some other user's have had the same issue, I was wondering what they might have done to correct the issue.
Thanks,
David

Normally there is a tick box that say connect auto when in range check no others have that ticked

Hi,
Thanks for the reply, that's in fact one of the first things I checked.
