OK, shadow, thanks, once I Disabled Wireless-Networking-Mode, all the rest of the Basic Settings turned grey (from black).
The problem is, re: the rest of the pages, I tried understand the PDF, but I couldn't. It's very very unclear to non-tech people which Tabs (and sections) to go to in order to totally disable wireless.
Which tabs do I go to in the Online Gateway to completely disable wireless?
Once wireless is Disabled, can I disregard all the Wirless security-settings the previous owner set on the router? Will the router be secure anyway, even if wireless is disabled?
(I'm working now on editing screenshots, to show what's displaying)
