WLAN Failure by last security and system update on G21, Android 12

JC67 ✭✭

WLAN no longer works after the latest update (Google Play Systemupdate Feb.1.2023, Securityupdate Feb.5.2023 ).

All attempts of troubleshooting (even after described instructions, network reset, softreset-etc.) are unsuccessful. 

A factory reset is out of the question for me.

I then contacted the support.

The support informed me about 14 days ago, that's a global issue and they are already working on a solution.

Yesterday (Mar,29,2023), there were two updates that did not fix the problem.

Security update status G-Play Mar, 1, 2023.

Android security Feb, 5, 2023

Android 12, Build 00WW_2_600

Wifi still cannot be turned on.

Is there perhaps a workaround as an interim solution (no factory reset)?

    Hi, if the March update has not fixed the WLAN issue, then I don't think Nokia has a solution. You really should backup your data and perform a reset at this point.

    Because with no serious words from Nokia, it can be a really long wait.

    that would be unfortunate and unfortunately reduces the confidence in nokia's products. otherwise, i am very satisfied with the quality.

    it's not too much to ask that a problem caused by software updates be solved promptly with error-free software updates.

    in the meantime, the error has existed for almost five weeks.

    i also don't really see the point of making a complete backup and performing a factory reset if it's not guaranteed that the error will be fixed by then.

    it would be good if nokia fixed the error now. after all, it affects the important hotspot and wifi functions.

    Several users have mentioned that a factory reset fixed the issue for them. That's why I suggested that. AFAIK, nobody claimed that a reset had not fixed the problem for him/her. You can bring yourself the convenience of working WiFi, hotspot, etc, by taking it in your hands instead of waiting for hmd - which is not so communicative. I'd have suggested waiting for a fix only if somebody from hmd was here and assured me that an OTA update would fix it.

    I do agree about your other statements. HMD should have assumed more responsibility, unfortunately they do not.

    the tip with the factory reset is also ok. it was not a personal criticism of you. The reasons why I do not prefer the hard reset I have already mentioned: time-consuming backup of all data and apps etc. and the error can be fixed by updates.

    The good news:

    Today there was a system update (00WW_2_640) march.05.2023 and wlan works fine.

    wifi hotspot still not (network reset and soft-restart do not help here)

    at least wlan works again

    even if it took a bit too long for such an important function, it restores my trust in nokia.

    best regards

    However, in general, a security or system update on a device may sometimes cause issues with the wireless LAN (WLAN) connection. This could be due to changes in the device's network settings or compatibility issues with the WLAN hardware or software. In such cases, it may be necessary to troubleshoot the WLAN connection or revert the device to a previous state before the update. It is also possible that the issue is not related to the update and could caused by other factors, such as network congestion or signal interference.

    yes, this is all very possible.

    All attempts to fix the error were without success.

    Factory reset is the very last resort and I do not do it when it is clear that it is a software error.

    In this case it was actually due to the security and system updates.

    After applying the corrected error-free updates, at least wifi works again (hotspot not at the moment).

  • Did Factory reset yesterday hotspot works smoothly.

    Shared internet, files with other device via hotspot.

    Thoroughly recommend it !

    after the April upgrade to Android 13 everything works fine, without factory reset. Also the access point works again.

  • I'm sorry to hear that you're experiencing issues with WLAN after a recent security and system update on your G21. Here are a few steps you can try to troubleshoot the issue:

    1. Restart your computer and router: Sometimes, a simple restart can fix the problem. Restart your computer and your router to see if that helps.
    2. Check your wireless adapter settings: Make sure that your wireless adapter is enabled and configured correctly. You can do this by going to Device Manager, finding your wireless adapter, and checking its properties.
    3. Roll back the driver: If you recently updated your wireless adapter driver, try rolling it back to the previous version. To do this, go to Device Manager, find your wireless adapter, and select "Properties." Click on the "Driver" tab and then select "Roll Back Driver."

    If none of these steps work, you may need to contact your computer manufacturer or a professional for further assistance.
