Hi all, I am on S1AWD1 and I am currently having really poor wifi at work on wifi6. Is there a newer software I could move onto which will fix this wifi issue?

Thanks

Not a Wifi or OS issue, it's the router that has poor coverage.
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?

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.

I have retry it

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... lmao

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

    Jesus. People got used to receive updates so fast from samsung that now if they don't receive it in the first week of the month it's like their phones aren't working and panic attacks starts to appear.

    Well there you go, EUX had to wait the entire length of my 3 week+ holiday in Tenerife to get what THL already had, baffling.
    But good to know there will be a path from it to the next OneUI 6 beta.

    In this thread, you can discuss and share the Mega links of new firmwares (OFFICIAL STOCK) for the Galaxy S23 Ultra 5G!
    NO CUSTOM ROM's and/or ROOT-talk

    How to flash the firmware to your phone:

    Odin.png


    1. Extract (un-rar) the firmware file (i.e. to folder C:\Odin) ***
    2. Download Odin v3.14.4
    3. Extract the Odin ZIP file (i.e. to folder C:\Odin)
    4. Open Odin
    5. Power OFF your S23 Ultra 5G
    6. Reboot Phone in Download Mode: Connect USB-cable to your computer. Hold down "Volume up" and "Volume down" at same time. While holding down, connect the USB-cable to your phone. Or use the command "adb reboot-bootloader".
    7. Wait until you get a blue sign in Odin
    8. Add the firmware files to their designated slots (AP in AP, BL in BL, CP in CP, HOME_CSC in CSC). USERDATA stays EMPTY!
    10. Click the start button, sit back and wait few minutes for the device to automatically restart.

    *** You can always find the LATEST firmware in message #2

    I have taken over these threads and they are dedicated to the memory of Henk, you can read more about him here:
