I've already got a little wireless home network, with just one router serving as both DHCP and internet access gateway for home wi-fi devices. The router and devices are set up manually, the way I want them (encryption, passwords etc).
Now, I want to get myself a wi-fi enabled printer. The manual states that setting it up is as easy as pressing the WPS button at the same time on both the printer and the router.
My router does have this button.
However, having read up a bit on how WPS works, I'm somewhat scared to press the WPS button as I now have an impression it will sort of cancel out my settings and pull some auto-created stuff instead. This would ruine my existing setup, and not all of my devices have a WPS button.
So, could anyone explain please, what exactly will the WPS button do if I press it in an already-setup network? Will it just cleverly pass my settings to the new device, or will it do something I'd prefer it to not do?
