Welcome to Seven Forums,

You might want to check out the Realtek site for the latest driver for your Wi-Fi adapter.

Also, see if it helps disabling the Power saving mode of your Realtek adapter in Device Manager, see image attached.

I've had this same issue, and further to that, I also can't hold a wireless connection if I'm running on battery power. I have NO idea what to do or what the issue is. Any luck with updating your drivers?
