All four lights on my Netgear ( power, lan, dsl and internet ) are glowing all the time even when the PC is switched off..........I think that is normal.
I think, too, that it is normal for the internet light to flicker ( your router connects to the internet, not you PC which connects to the router, so there may be some inbound connection attempts happening.........if bad ones, being fended off by the router firewall)
If you open your browser and access the routers web interface, go to the "Quick Start" section and look just under the area where you can, if you want, create your own password/user name and just below it you will see the box "Enable Wireless"..............if that box is not ticked, the wireless capability is switched off...which is what you want on your current configuration.
Ensure that box is not ticked and all will be well...........although creating your own user name/password is strongly recommended.
