Full fibre. Wifi/Internet drops, slowness. Samsung s23 ultra

[LagrangeL2]

My wife's iPhone shows no issues but despite a restart and a monthly update being applied, my mobile experiences NUMEROUS instances of wifi/Internet pauses/lack of online response and full disappearance of WiFi (WiFi icon will disappear and/or it has a warning exclamation mark). Apart from the WiFi icon dissappearing, I can't confirm if the Internet/fibre link is also at fault. The router is literally 3 metres from me.

Tried a speed test on my phone and it won't connect to the the test server after 5 minutes!

Hey @LagrangeL2 I'm sorry to hear that this is happening, I can appreciate how frustrating this must be. We will need to run some tests and checks on the service but we aren't able to do this on the Forum. So we can help, please drop the Social Media Team a message here or speak to the dedicated Home Broadband Team on 0333 304 0191 or via LiveChat.

@LagrangeL2  Which brand and model is the mobile phone that is experiencing problems?

Please go to the router logs and look for any error messages. If the log is a bit confusing, then cut and paste the bits you want help with.

@LagrangeL2  The auto spelling correction changed what I had typed, originally I wrote "The S23 is broken". 

If you type "Samsung S23 WiFi issues" into Google you will get many results.

I assumed you meant borked.😂

I have this router https://youtu.be/4e7gtxZG7hw?si=LCYDrDz5Hr3JGxmS which doesn't seem to support WiFi 6 and which is what the sammobile article says to switch off on the router.

On the phone, go to WiFi, 3 Dots at top, settings, and turn off the turn off the auto turn on/off function and the Hotspot 2.0 function.
