iphone 11 wifi often losing connection

I’ve had an iphone 11 for a bit over a month now and everyday get faced with brief periods of no internet on my wifi. I have tried connecting to other wifi networks (I have Google Wifi), and the everything loads fine which makes me think it’s a wifi problem and not the phone, but when I use my old iPhone 7 and my other family members devices the wifi is working. Also, when I switch to cell service during the period of no internet I get a stable connection. So multiple times a day, my phone stops receiving internet from my wifi (but specifically my phone) for a few minutes. I was just wondering if this is a problem with my phone or the wifi? It seems like it’s the wifi but if it’s fine for everyone else’s device it makes me wonder if there’s something wrong with the phone.
