bell wifi keep disconnecting starting from around 130 am

so i had recently just switched over from rogers, and ive noticed that the bell wifi would always keep disconnecting. during the day it would disconnect around twice ish, however, during the night its every 30 mins or less it would disconnect. on top of that during the day i would get around 4 bars but during the night it would drop to 2 bars, making loading tabs and such a massive hassle.

is there any fix?

thanks!
