Another desperate XZ1c user here with my story. Unlike you guys, I've had the isse only since Pie. But then again, I've had this phone for only 6 months now. I love it, but this is an extremely annoying bug (I'm assuming it's a sw issue). Phone's up to date and hasn't been tempered with, not even the dev options have been touched. It keeps disconnecting from wifi, reconnecting to it, disabling it, connecting again and so on, until it simply gives up and no wifi network is shown. Restarting the phone fixes the issue, but it represents itself inevitabily after a day or even less. Toggling the wifi or airplane mode almost certainly triggers the issue. I'm sorry I can't add anything new to the thread at the moment, except my voice. I'll share if I find anything useful. EDIT 1 @Phnils #92 Since the day I got the phone (hence without the wifi issue) I've had a static IP, binded properly to its MAC address, and my router's DHCP has been assigning it correctly. These are things I work with and I'm pretty sure we can rule out a networking problem. I don't know why it worked for you, but I know I keep having the issue with both static and dynamic IPs.

Hi, I've also been experiencing a similar issue for the past month. I'm desperate for a fix so I'll share my experience because it may be related to yours. My phone keeps connecting, disconnecting, searching, disabling and reconnecting to any (this is a difference) wifi network. When it manages to stay connected, internet speed is extremely low. Restarting the phone fixes the issue temporarily, but it arises again in a day or even less. Toggling the wifi however seems to trigger the issue almost certainly. This issue is not new and Sony (or Google) still hasn't done anything: https://talk.sonymobile.com/t5/Xperia-XZ1-Compact/Wifi-connection-problem/td-p/1315030 Please share if you find anything useful or interesting.
