Thanks but the router is a high performance one that works perfectly with all laptops and phones within the office including my previous S21 Ultra but this S23 has a common fault with Wifi6 and I was wondering if that has been fixed with a newer software?

Wi-Fi 6 connectivity issues are hounding Samsung Galaxy S23 Ultra owners
Some Galaxy S23 Ultra units are apparently having trouble connecting to Wi-Fi 6 networks
Galaxy S23 Wi-Fi connection issue has an easy temporary fix, here’s how it works
The Galaxy S23 series is, as a whole, pretty great. All three models serve their purpose very well, with performance ...
Theres also multiple reddit threads, it seems wifi6 is an issue with Galaxy devices in general although I never used to have the issued with my S21U. In the UK I have unlimited 5G so wouldn't be an issue but I am currently in the UAE and data is expensive so I rely on the Wi-Fi.
If your phone doesnt have the issue you either dont have wifi6, or it shows its a hardware issue?
WiFI 6 user here - no issues at all, however I had similar problem when I had 160Mhz channel on, after switching it off problem was gone.Wi-Fi 6 connectivity issues are hounding Samsung Galaxy S23 Ultra owners

None of these sources mention any issue with signal strength. They're just mentioning issues like Wi-Fi not having an internet connection but it's connected to the network, etc... lmaoWi-Fi 6 connectivity issues are hounding Samsung Galaxy S23 Ultra owners

Sorry by poor WiFi I meant that it was always connected but with the " connected without Internet "
Managed to disabled WiFi 6 on the router and it's working fine now so definitely a Samsung issue with WiFi 6
NO problems here, with Xiaomi ax3000 first was excelente and now with xiaomi ax9000 is bether....

No issues with my S23 Ultra from T-Mobile running the U1 firmware. My router is an Asus RT-AX86U. Both devices running the latest firmware.

Unsure, S23 is not my daily driver (family). But what i can say is that the phone is a lot more fluid ever since One UI 6.1.1
Actually, LTE TDD is not used anywhere in Europe, I'm not sure if it's even used outside of China. What Samsung is trying to say there is a big question mark for me.
LTE FDD is what's mostly used. I've read somewhere that many operators in Europe will disable 2G completely from 1st May, so this patch could be addressing that. Some new emergency channels are being opened up instead.1 -
