Thanks for that. I have given up on Carbon. I sent a log to one of the developers and he said:-
"I'm checking your log now. Seems chromium is the cause. That means the Webview inside my Carbon ROM is not working."
He tried to put it right with a patch. It did not work and as it was a matter of working on the framework we mutually agreed it was not worth the struggle.
From what we can see the Carbon team are not planning to create a Marshmallow rom - so I am not going to spend any more time looking at their software.
I am using CyanogenMod 12 for GalaxyTab-7..7 and it is stable. I'll try their Marshmallow when I get a bit more time.

Also the 5.1.1 built-in browser seems dead to me too. Just don't use it, get Chrome/FF instead. Wi-Fi is working fine for me on several different routers, even 5GHz N-mode (having separate SSIDs for 2.4 and 5).
A bit of salt here - my wife got a pretty darn hard lock-on today and is incapable to switch the Tab off! Still waiting for Tab to see wtf happened.
