Very slow wifi

[AmirUddin]

Just bought the Samsung S25 Ultra and I have noticed the wifi speeds are very slow. Struggles to go above 200mbps. 

On my galaxy tab s9 and other devices I get 1gig speeds (none are on the UI 7) except s25 ultra 

Tab s9+

S25 ultra

Is there a fix to this? Or is it a software issue or hardware issue?

No problem here

Try going into the developers mode and disabling WiFi scan throttling. It will impact battery performance a little, but it should allow a better network speed consistency.

Seems like this worked but will see in a few days time. Thank you

Having the same issue. Restart solves temporarily but always reverts back to ~250mbps.

S22+ consistently showing ~940mbps for my 1Gbps broadband.

Really hope this gets fixed with an update.

Did they manage to solve the problem? I have already updated to the latest version of March, and the speed remains at 250 mbps.

Nope

Go to. Developer Mode settings

1. Disable wifi scan throttling

2. Set wifi download speed limit to 15mbps

3. Reset the download speed limit to unlimited

This should solve the problem

Doesn't solve, the problem returns a few minutes later.
