WiFi issues still not fixed after resetting network settings

[Rio3505]

It's getting to a point where I can't even rely on this phone to have WiFi sometimes and that's not good

And you can replicate that issue in other locations using different routers. If yes contact Samsung support via Members app and let them deal with it

What do you mean

Hi @Rio3505 

I totally understand and appreciate that when a core feature does not work as intended then this can be frustrating and inconvenient.  

May I ask ~ What happens when you do make a Wi-Fi connection i.e intermittent  / Slow / Non existant ?

Does connecting to any Wi-Fi source return with the same issue. 

There js a diagnostic test tool found in the Samsung Members App to see if that highlights anything. 

Other generic troubleshooting steps are >

Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. Alternatively long press the power off button and then long hold on Turn Off to get to Safe Mode. 

And

Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop or use a Tv's USB Port to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too { Possibly excluding the s²⁴ Series of phone's } 

Just as a process of elimination  ^

If this continues then as @Tourbillon De La Vie has suggested please send this as feedback with any relevant error reports to Samsung directly via the support section in your Samsung Members App. 

A Samsung Service Centre can assess your phone if necessary. 

If i can be of any further help please don't hesitate to ask  😎
