Constantly Have to Turn Wifi On & Off

I have a Blu Vivo 8 and recently (a little less than a year ago) it started having issues where the wifi would say it is connected, but it was not really. You would have to turn the wifi off and turn it back on for it to work again for a while. I thought it was a corrupted file issue, so I did a factory reset and cleared cache files from bios. This worked for a day, but then the issue came back. I also have similar issues with Bluetooth so I assume the issue is the wifi/BT board. But I cannot seem to find that part or a way to test that. Any ideas?
