Wow ... this IS disappointing in the extreme ... sooo many people (and sadly I am one of them) having the same WiFi problem, and on a top of the range mobile that costs as much as an excellently specced laptop.
My previous phone - an HTC ONE SV connected flawlessly, consistently and constantly to my WiFi. My Z5 connects (reportedly @ 144 mbs) for a short while then displays the ! over the WiFi icon as detailed by so many disappointed owners previously in this thread and then refuses to connect to the internet. With WiFi turned OFF the 4G connection is excellent. So this must be a Z5 WiFi problem.
SONY - its your responsibility to sell items which are FIT FOR PURPOSE. I love the Z5, in all respects bar its WiFi connectivity which is frankly appalling. YOU need to get this sorted, otherwise this handset is NOT FIT FOR PURPOSE.
We pay the money for a premium device and end up with less than good performance ... the ball is decidedly in YOUR COURT SONY ... what are you going to do about this?

An update - I have scoured the forums for help with this issue, and though I tried the following earlier with no success I repeated it and seem to have got somewhere;
I unplugged my router/Hub and left it for 5 minutes. I went into the WiFi settings on my 'phone and told it to forget my Hub and then turned off the 'phone for 5 minutes.
I re-powered my Hub/router, and did the same with the 'phone. It 'found' my Hub, and asked for the p'word, after entering p'word the 'phone connected to my Hub/router and (2 hours later) I haven't experienced an Internet drop or the ! on the WiFi icon.
I hope this has fixed this issue as I love the 'phone - but having seriously fragile WiFi/Internet connection will REALLY spoil it for me

Yes I'm also one of the victims with the Z5 Premium.
Final solution is to switch to a brand that makes working smartphones. And make every potential customer/victim aware of this before they make a mistake.

I had the same problem on my Sony Experia Z5 Premium and I managed to resolve it in less than five minute. The solution might not be generic as there is a variety of WI-FI routers out there. To be specific I am on NETGEAR router with a WPS button. Follow the following steps if your router has the WPS button I am very positive that the problem will be resolved.
1. Go into settings
2. On Wireless & networks select the WI-FI option
3. Ensure the WI-FI button is on
4. On the top right corner click the three dots
5. From the drop down menu select Advanced
6. Select WPS Push Button
7. Press the WPS Button on your router until orange light starts blinking
8. Once your phone is connected the light colour changes to green
9. If connection fails repeat the process from step 7
I hope this will help you to resolve the WI-FI issues. Alternatively WPS PIN Entry can be used to connect the device to the router.
