Thought you needed a router password and not the one for the computer. My mistake. That list is only for the default password for the router sorted by brand.
arkie, to access the router settings a browser is used. I have a Linksys router and put http://192.168.1.1/ in the browser address field. Then I'm prompted for ID and PW. Default was to leave ID blank and use admin for PW. [I've changed this since].
This info came from the router manual. If you lack a manual, try finding it online. If a router is present, one needs to know how to access it in case a setting needs changing [it's also educational]
