Searching for files/folders over X amount of characters

I need to find any files and folders that have more than 142 characters in the title. I know I can do this by the following command in Terminal:

find -E . ( -type f -or -type d ) -and -regex '.*/[/]{142,}'

And I can browse to a direction doing: cd /directory/folder

However the location I wish to check is on my NAS and I can't quite work out how to browse to the location in Terminal. I've tried cd /nas-name/sharename and the same with the IP but it doesn't work. So I'd appreciate if anyone...
