Poor Wi-Fi Speeds with iOS17.4

Howdy folks,

I have an iPhone 15 Pro. After the recent update to iOS 17.4, my wi-fi connection is terrible quite frequently. Signal strength is 3 out of 5 bars, but data traffic to my phone moves extremely slow. It takes 20 seconds to load a text Web page, and the Sirius XM app tells me that I'm not connected to the Internet... My iPad doesn't have this problem, but my M1 MacBook Pro does. The issue goes away for about 24-48 hours only after I power down the phone, wait for 10 seconds, then boot up again. Warm reboot or turning airplane mode on/off doesn't help. After cold boot, the wi-fi speed is back to normal for a day or two. This started happening after the update to iOS 17.4, so I don't suspect a hardware issue. I did not drop or abuse the phone. The phone is only 3 months old.

My M1 MacBook Pro with the latest Mac OS also has this issue, but to a lesser extent. My Windows and Android devices don't have any of these wi-fi issues, so I guess it's an Apple thing.

Thanks.
