Changing security settings on Thomson 585

[#1]

This may be a dumb question!
My Voyager router went caput so I have been supplied with  a Thomson Gateway  router. It works fine - no setup was needed -  but I can't see where to change security settings - add MAC filtering, hide SSID etc. The security page (http://www.plus.net/support/broadband/wireless_broadband/secure_home_network.shtml) talks of an instruction manual, but there wasn't one and I can't see anything on the configuration web page.
Guidance welcome.
Thanks.

I've not found MAC filtering - ?
To turn wireless on / off push the buttom on the front for about 6 seconds or so.

Hiding your SSID doesn't make your wireless any more secure unless you've got all security disabled!
Your PC is still going to broadcast your SSID periodically
Also, anyone who can crack your WPA security will have no trouble spoofing a MAC address.

Frankly, the manual is poor.  It does not document all the features so you might still be able to do the things you want, despite the fact that they are not mentioned in the manual.

I couldn't agree more, which is why I am rather slowly gathering the material together from all the snippets here on community and anywhere else I can find it.
but there are plenty of other manuals on specialised tasks here:
