If the option "Take bug report" is greyed out, please make sure that you have enabled "USB debugging".
When you select "Take bug report", it may also take a little while for the phone to create the log. When it's done you get a notification in the notification bar that you tap and share to Google Drive.
But please make sure you also have "Enable Wi-Fi Verbose Logging" enabled.

Ok, new update on the issue - the wifi and the mobile data are gone in the first 10-20 seconds after I unlock the phone. After that it is all fine... In locked mode of course no wifi or mobile data is available and I do not get notifications while phone is locked... Way to go Sony... I will now try the logs as mentioned above!

It seems to be three different errors.
First of all, as mentioned, The wifi takes 15-30sec to "wake" after unlocking phone wich makes it unuseable during that time.
Secondly, The exclamation mark comes randomly, and wifi stops working. A restart of wifi then helps. Sometimes it resumes wifi by its own.
Third, no matter what setting i use in "wifi/advanced/keep wifi in resting mode" it seems NOT to keep wifi. For example:when i check phone first thing in the morning, regardless off setting, I get all my notifications when i start phone, so wifi has been off and not recieving any thing during night even if ive choosen "Wifi never sleep". Although this is not 100% either.
Something is very fishy with the wifi on this phone.
I will send Rickard, yet another bug report from this morning.

My z5 premium WiFi is hopeless. Drops out all the time. My mobile just keeps buffering and do anything over WiFi. Love the phone but can't use it. Can't stream tune in radio WiFi is Crap. Even at full signal.

My Z5 Premium works fine, and I've been using a LOT, and when I say a lot, I mean, quite a bit of different routers and it has been working fine.

It sounds like you may have "Extended standby" and "STAMINA clock" enabled under Settings -> Power management -> STAMINA mode. In this case, the phone will turn off WiFi and mobile data when you're not using the phone. There will also be a delay before they're connected again when you turn on the display. The delay will be minimized in future software updates but if you want to keep WiFi connected when not using the phone, you need to turn these off.
When WiFi stops working while you are using the phone, could you please try if this also happens if you set the phone in airplane mode?
If it also happens in airplane mode, could you try if it happens in safe mode?

My latest msg. to Dear Rickard
Further then this, I also noticed that the WiFi stopping in the middle of browsing/facebooking and so on, has been MUCH better when turning off Stamina mode.
So it seems to be Staminamode up the Wifi regardless if "extended mode" is on or not!
Sorry about delayed answer.
I can absolutely confirm that the logs were taken right after the WIFI problem occured.
I have also been testing around alot with the settings, and i think I pinpointed the problem.
I seems to have to do with the Stamina mode.
When the "extended standby" is enabled, the problem occurs frequently. When off, almost never.
Granted, the "extended standby" shuts of wifi, but the problem remains after "waking up" the phone, and as said before, alot of problems connected to it since its a) takens 20-30sec to connect, b) doesnt connect at all, and I have to restart wifi.
after all this time I have now shut of Stamina mode, and the phone works just fine, even though the battery performance has been reduced significantly :-(

First time in Sony site, sorry if i make mistake
I have also same problem!
Bought Z5 Dual in Dubai, using in Central Asia. Phone is perfect for me, I am a die hard Sony fan. Using Sony devices and mobiles last 10+ years. I have ADSL connection at home through linksys wag120N. Wifi of other phones including wifes Z1 works perfectly but not on my Z5 dual. First 2 month couldnt connect at all, no wifi logo/sign. It just says that connecting/obtaining IP for fraction of second then it saves, thats all. 3 days ago it connect magicly for 15-20 seconds and it dropped. i have tried everything like different channels on router, airplane mode thing, dhcp and so on. Thought maybe router and z5 had connection issue but in the end tried TP-link wifi adapter (SOFTAP). Same applies here, Z1 connecting perfectly to Softap, Z5 connects, internet is working but after 10-15 seconds dropping despite wifi sign/logo is still there. I have to forget and reconnect and it will disconnect one more time in 10-15 seconds. It is unbelievably annoying, dont know what to do. And as i said as i bought it from Dubai i do not have chance to change it despite all guarantee documents are available. I really hope you have some abra-cadabra thing to fix it
P.S. Not using any Stamina mode!
