Hi10 Pro Wireless Signal Poor

Hi, I have a Hi10 Pro CWI529 Hi10 HQ64G42180300670 with keyboard. It worked well until it tried to update windows 10 and got into a reboot loop. I reinstalled windows using a flash drive and it works but (1) I lost the icon to switch from windows to Android and (2) the wifi card is running and driver applied but has very poor wireless signal. I’m currently using a wireless USB. Do you have any suggestions or steps I can take?
