Serial Number of the Modem cannot be changed. It is hardcoded to your modem.

Find wep key 3347nwg -006


Try Password: admin, 1234, serial number of unit (written underneath)

Or you could connect to it with a Ethernet Cable and open web browser and go to 192.168.1.1 or 192.168.1.0 or 192.168.1.254 and you can access settings from there and change WEP password.

Last resort, just use the reset button on the unit.

I have an At&t router and i need the password to set up and iPad. How do I find out what the password is?


Well, if the modem you have is a 2-Wire wireless router/modem, you need to pick up the router/modem, look on the bottom and it has the serial codes and what not there. Look at the number/letters that have ( ) in front and back of the code and that is your wireless code without the ()'s of course..

Hope this helps!

I have a motorola modem and i wanna change it to a modem that have a 4 port switch how can i change it


You really don't need to change the modem. All you have to do is add a 4-port wired router (or wired/wireless one if you want to add the wireless capability). Netgear and Linksys units are easy to find at most retailers. Simply connect the router to the Ethernet jack on the modem, then plug your computer(s) into the new router.

This is much easier than changing the modem itself. You don't need to get your service provider involved if you just add a router.

Wireless laptop with win.vista can't connect to my 2wire


1st Look for a wireless network, it will be named 2wireXXX (XXX = the last 3 digits of the serial # on the bottom of the 2wire modem.) When it asks for a WEP or a security key, it will be on the bottom of the modem in between 2 bar codes and it will have [ ] around it, this should be a 10 digit #. If that does not work. I had a problem with my MAC and my Windows VISTA 64 BIT Laptop not being able to keep a stable connection with the default wireless username and password.
To get into the 2wire: Open a Internet window Address Bar 192.168.1.254 Home network "At the top of the page" then click on wireless settings "Also at the top of the page" Then you are in the wireless config to change the information.
What i had to do is change the wireless authentication to WPA-PSK and change the wireless password (Use a 10 digit Number as the pass-code, a phone # would be a good suggestion) , what you also need to do is change the name of the network along with the channel of the wireless, it helps if you take it all the way up to 11. Then you should be smooth sailing all the way. :-)

2wire 2700hg-b modem


if you have posted the correct model, you cannot connect a modem to this router as it has it's own built in modem, so in effect the routers modem will not configure properly, remove your modem and try again as there is no reason why the key code numbers should not work, unless you have caps lock on when you should'nt or visa versa
