My Galaxy A40 keeps disconecting from my wifi after an update on 26/05/20. My friend also has an A40 and updated his phone 1 week later and instantly had the same issue. The issue is only happening on my phone and not on my laptop, ruling out the posibility of my router being the issue.
Hi, @JDM3, hope all is well. Can you perform a Soft Reset please, and let me know if the issue persists? This doesn't delete anything from your phone, it fixes any minor issues that may be occurring. To do this, hold the 'Power' button and the 'Volume Down' button, both together for ten seconds and your phone will restart.
Go into settings, advanced functions or something like that (do not know the translation for it), then go into restore and use the restore network settings. You will have to re register all wireless devices, if it does not work you may consider a hard reset. Do my procedures after trying what @CarlH if it does not work!
Have a nice evening
Hi @CarlH, I have peformed a soft reset as you suggested. I had done this about 2 weeks ago with no improvement, however I have just done it again and it seems to have fixed it so far, fingers crossed. I will see if it droppes out in the next few hours to be sure.
Hi @JDM3 ,
Please check if you have the Wi-Fi set to Off or Never during sleeps period on your phone by going to Apps> settings> Wi-Fi> More> Keep Wi-Fi on during sleep.
If this is not the case, confirm that you don't have any power saving settings on your phone: Apps> Settings> Device maintenance> Battery. Can you try connecting to a different Wi-Fi network?
