Hey, thanks for the help, but I had already tried all of that and nothing helped.
But this is what I did at last (again) which is doing a software repair again, Resetting the router and it's working again.
I can't really point out where the problem was ( phone or router) but I'd like to think it's the router fault.
If the problem reappear I'll report back.
Again thanks for your help.

Same problem here on both Xperia z4 and 5. WiFi works until you disconnect, then it cannot connect any one. Problem happened only after updating android, other devices still working with WiFi...

Even this fix doesn't work for me!
I have all of the problems you've mentioned on my Z5 after update to Nougat, even had it sent away to be 'repaired, though I insisted to Sony UK repeatedly that its a software issue. Battery was replaced etc and still haveing all the same issues.
Alas, sony are refusing to acknowledge the problems with 7.0.

The "can't connect to this network" is very usual in xperia phones and I have seen a few complaining about it. One thing that you should try out is to power cycle your router. All you need to do is press the power button and wait for 30 minutes before switching it on. Now search for the wifi connections once again and hopefully it will work.

To add the Wi-Fi network again, you try to do these steps:
1.Open your device's Settings app.
3.At the end of the list, tap Add network. Tip: On Android 6.0 and below, to see Add network, tap More
4.Enter the network name (SSID) and other security details, if needed.
6.You may need to enter a password to connect.

WiFi and other problems are common, not only for Sony, but Pixel, OnePlus and others share the same problems.
Here is a nice howto for common Oreo problems.
The WiFi part is clear about the steps to take.
