Slow Internet speed Mac OS Sequoia 15.3.2

Mac OS Sequoia 15.3.2 on M1 Max Studio and the internet speed on the download is a snails pace. 1-2mbps & when I check the house wifi on any other device doing a speed test I'm getting around 46mbps download and 16mbps up speed. SOMETHING IS DRASTICALLY WRONG! I never had an issue for over 2 years with sonoma and the day I upgraded to Sequoia, everything is slow. The internet is almost unusable. On phone, xbox, tablet, tv all completely fine, but on the Mac Studio with sequoia 15.3.2 forget it. I have also done all the recommended, like turn off firewall, flush dns, reset router, forget wifi and reconnect. APPLE PLEASE DO SOMETHING FAST!!!! I work from home and need the internet.
