Wi-Fi drops constantly since 4.0 OTA update


This is my first post here. I hope I’m doing it right.

I just updated my FP4 from iodé 3.4 to iodé 4.0 via OTA. Before, I quickly searched on the web to find any warning about doing this but found nothing.

However, since then, I noticed the Wi-Fi icon went off and back again every 3s. Indeed, going into the settings, mh phone was constantly connecting and reconnecting, not maintaining connection more than a few seconds.

I tried the following, in this order, but in vain:

  • reboot
  • disable iodé app
  • forget every known networks
  • reset wireless settings (from the Settings > Reset panel)
  • change my WiFi password
  • change my WiFi security level (WPA2 AES to WPA3)
  • switch to a 2.4GHz network
  • reboot my WiFi router

I even tried to disable MicroG by removing the Google account I just added after the update (might be important to know).

I will continue to try some combinations of the previously listed actions, but I don’t expect much from this.

Do you think I should downgrade ? How ?

I will provide any missing info, so don’t hesitate to ask.

Thank you very much in advance!

(I do speak French but figured I might have more answers with a post in English, answer me the way you want to)

iodéOS v4 beta builds of FP4 have been tested by dozens of people, no one reported an issue on wifi, I’m sorry…
What you may try:

  • reboot to recovery, clear cache
  • in settings → applications, display apps, then enable system apps (three-dots menu), look fr vendor.qti.wlan, clear storage
  • open an issue and post a logcat : Issues · iodeOS/ota · GitHub

or maybe another possibility
