"If your router is not new as has had a previous user then only way would be to reset the router."
I was the previous owner. Sadly I couldn't remember the password.
I've yet to get the whole thing working, here's what has happened:
1. Reset router
2. Login to the admin page
3. Attempt to add security/password
4. Page crashes after submission
5. Can't log on with new selected password or into the admin page again.
I was trying to do it with my phone yesterday. It was fine for the first part, but once the page crashes there was nothing to be done!
I also couldn't get the PC which was plugged into the router to visit the admin page; how do I set up Windows 7 PC to connect to the network so I can do this? The network/connections manager is something I've not had to deal with much on Windows 7 and it feels quite different to XP.
I'm going round this evening again to give it another go. It dawned on me after I left that I could have been using a laptop with a wireless card to sort the admin page stuff... which may have been more successful.
To be completely clear the goal of setting this up is to access music etc from the main PC on:
1. Laptop
2. Phone
3. PS3
4. iPad
Any advice relating to getting these set up would also be welcome.
