Had to re-install software. Can't get past the admin/password box. Typed in the default "admin" but the software wants a password. Can't restore database or get into the application.

Try using the same security settings as your existing network by selecting the "Use the same security mode" check box when setting the your extender.

I have the same problem but can not even log in for the 1st time. admin and password do NOT work. And when I checked the ip address w/ the ipconfig /all aomand in a command prompt, I found that it has ip address 192.168.5.1 So when I tried to log in to that page, it prompted me for a user & password. Again, admin and password did NOT work. Also, tried 1234 for the pasword with no luck. Is this box defective??

if you want router login password you can try user name as admin and password as admin/password if you want to check the wireless password set up to your computer then

1) press and hole the windows key on keyboard which is next to ctrl key and then press "R"

2)In the box type cmd click on ok

3)you would get a black screen with a blinking cursor where you can type

4)type " ipconfig " hit enter

5) ther would be few numbers typed next to default gate way (eg: 192.168.1.1)

6) type the default gate way number in the adress box of internet explorer

7) it would ask you for user name and password  you can try user name as "admin "and password as "admin/password " it would direct you to router page

8)there you can check the wireless password in wireless settings option.

You need to factory reset the router by holding down the little button on the back of the router (use a paper clip to push it). After doing so it will reset the password to the default which is admin.

If you have forgotten your Linksys router password, the easiestthing to do is to reset your router to the factory default settings. To restore therouter configuration to factory defaults, hold the reset button on the unit for30 seconds.

Once your router is hard reset, you will need tologin and reconfigure it again.

To reconfigure your Linksys,connect a PC to one of it's Ethernet ports, load a web browser, and go to theURL http://192.168.1.1/. This will take youto a popup box which asks you to enter a username and password to login to yourrouter.
Linksys Default Password

On older Linksys routers, the default username is blank and thedefault password is "admin." On newer Linksys routers, both thedefault username and the default password are set to "admin."

Once you are past the login screen, you are able to reconfigurethe Linksys router.
You want to go to the management tab and change the administrator password tosomething else to keep others from accessing your router.

You could try "admin" as the username and "password1" as the password, or "admin" as the username and no password. If neither of those work, you might have to contact Linksys tech support.

Once you get into your router's settings, there are several things you can do to limit access to your router. The first thing is to change the default password. You can also change your network name (SSID), enable MAC filtering, or turn on WEP, WPA, or WPA2 security, depending on which options your router and computers support.

The default login and password is admin
If you still have difficulties because you had changed the password, the you can reset the router back to the defaults by :-
Pressing the pinhole reset button with power on for 30 secs, it should restart, then enter the router's URL configuration in your Browser
http://192.168.1.1
