I am Baffled!!! as to how the following could happen. I am asking about the moving of my router/modem to my girlfriends address and connecting to her new ISP and Laptop

I connected her Toshiba laptop (wireless) with 2nd hand (mine) netgear router/modem (DG834PN) and her new plusnet ISP. I simply connected all devices and wihout doing anything! including entering any data to the router it connected to my web browsers.

Now her laptop was configured to connect wirelessly to the above router when it was connected to my ISP at my address. So when I took the same router/modem to her address (30 miles away) and connected it to her new laptop and new ISP (hers: 30 miles from mine) that was just set up it worked without any new configuration or entering of data including without her ISP username or password. This has confused me as to how this could happen so looking for some explanation. When I looked at the router configuartion the settings where identical to when it was connected to my PC and ISP, including it had my ISP username and password in the boxes, despite being plugged into her telephone line!!!!!!....this has baffled me

I did use the wizard in the modem to reset the username/password that came with her ISP (even tho it asked me why did I want to do this wen i had a connection) baffled!!!.......how could it connect with all my ISP details to her telephone line etc.......would love to know how please!

Is she using the same ISP as you? if so then it is possible that your details would work on her connection. Also, If you are on a DSL or similar, the router will always recieve packets which might make it think you have a connection.

first think about how adsl works, it's not a shared resource, at the other end of your dedicated line there's a card putting out the broadband signal, all it needs is a modem to pick it up. It doesn't have to be secured.

now a cable connection is a shared resource and needs a user name and password or IP or something to allow it's modem to tap into the signal, by necessity this system is like a huge party line and needs to be secured

No. Try not. Do... or do not. There is no try.
