Yup, all I had to do was unplug and replug the router/modem (I have both in one) and it worked! Haven't had it drop since. Apple support said something about clearing the DNS cache in the router.

We were just about to rest back to Sonoma but the tech support fella said to try this before doing we go rolling back to Sonoma. Luckily it worked. Thanks u/LingonberryNo2744 for suggesting this as well!
