Another one with Z5P here chirping in.
Had the phone since Nov 15 and had this problem the whole time. Went into the O2 shop (UK) and their "Sony Ambassador" told me that Sony know about the issue and will be issuing a fix soon, that was 4 months ago and NOTHING yet.
Sent phone off to O2 repair 2 months ago and they sent it back with a letter saying "we couldnt find the problem" even after they phoned me about it to ask what was wrong with it.
Got to the point now where I cannot keep up with this, I use wifi in work a lot and at home. NO OTHER device in my house or work does this.
Phone going back to O2 tomorrow for repair again and I know they will do the same.
I see some people are saying about new hubs and changing settings, Its all well and good updating your own network to the latest firmware but you should be able to use it out and about where you have NO say or access to their settings.
This phone should just work out of the box on any wifi network, regardless if the hubs are running the latest firmware or not.
Anyone from Sony want to chirp in here with a few words about the O2 Ambassador guy or to acknowledge this problem?
£600 phone Sony, NOT GOOD ENOUGH!!!

same problem faced by my z5p here until I have changed my router channel setting for the wifi 2.4GHz from auto to a dedicated number, says channel 7, the problem is solved so far and no disconnection again. I am using asus ac66u router. Hope that it can help.

I had the same problem to the extent that the WIFI was not connecting at all ! But this only happens if you have android version 5.1.1.
Please check the version of Android in your device --I did a factory reset and then choose the software update that will directly land me to Android Marshmallow.
I had another upgrade to 6.0.1 --and here also wifi working perfectly no drops and always showing full strength!
Have a try!

So my Xperia Z5 Compact has just started doing this since the lastest firmware update to 6.0.1 - was working fine before. Have tried everything including software repair and factory reset (which doesn't give you the option to reset the firmware, nice going Sony) and still nothing. Sony suggest sending for repair meaning I need to purchase an additional handset in the meantime as they don't offer loans for something that they have broken. Terrible service. Why you can't just roll back to a previous OS version is beyond me - that would have been fine for me until a new, actually fixed update came out.
I'm guessing they'll deny that there's anything wrong with it when they look at it and it'll be miraculously working again when I get it back. Either that or they'll say I've damaged it in some way, which will be complete rubbish since everything was working fine until the latest update.
Does anyone from Sony actually check in on these threads? The guy I spoke to said that this issue was not a known one, so there's clearly not a lot of communication, given that this has nearly 100 posts about it.
EDIT: before sending off I attempted another Software Repair through Xperia Companion, just to make sure. The software repair process couldn't get past the point where you are supposed to hold down the volume key and plug the handset back into the PC - instead of the repair process continuing, the phone would just boot into safe mode - tried about 10 times with the same effect each time. Something is definitely up with my handset since this latest firmware update. What a joke. I've spent over £30 on sorting out a new (rubbish!) phone to use while the phone is off for repair, and Sony have said they won't cover that cost whatever the turnout of the repair.
