WiFi issues on tab s7 plus since one ui 3.1

Hi , since updating my tab s7 has issues with WiFi speed,  it shows alot slower on ookla speed test than my note 10 plus 5g , reset settings which cured it once but its not working now and my tab s7 is so slow at opening you tube and Netflix for example .

Is this a common issue since update ?

My Note 10 plus 5g is on one ui 3.0 and doesn't have these issues

Yes! It's been driving me crazy. I have the Samsung Galaxy Tab S7 WiFi version and since the One UI 3 update the WiFi has be VERY slow. Youtubealso crashes with me as well as basic Internet browsing.I've tested my WiFi with other devices and they have no issues. On my tablet I'm getting 10 mbps but on my other devices I'm getting 100mbps+

I've had similar. Our WiFi is BT 900 (gigabit), but even close to the router the speed can be only 40mb/s. I found it helped if I cleared down the cache from all apps and then switched s7+ off. Then got back too 500+
