goto connections, right click local area connection, click support, then details.

Hope this helps.

II have the modem SL2-141 and I change the password and now I forgot it? How can I recover it or reset the password?

I believe the Siemens "SL2-141" is a wireless router (not a "modem"). So I assume you are looking to retrieve/reset the password for your router. (If that's not correct, please let me know.)

There are typically two separate passwords used with a router, and it's not clear which type you're referring to. Are you trying to access the web-based configuration page for the router (for which you need an administrator password)? Or are you trying to make a wireless connection to the Internet via the router (for which you need the wireless security key)?

You may be able to retrieve either password (or both). The administrator password would be stored in the computer that was used to configure the router. The security key should be in the computer which configured the router, as well as any computer which made a wireless connection to the router.

You may find it helpful to have the owner's manual available. (If you don't have that, you may download a copy at:

The web-based settings for the router should be accessible at this URL (for the computer connected to the router):
The default user name is "admin", and the default password is "admin" If you can access those settings, you should be able to view the security key, or to reset the key (see pp. 99-101).

Alternatively, if the passwords are stored, you should be able to retrieve them by installing some free software.

For the computer that configured the router, download and install this program:
RouterPassView by NirSoft

For a laptop that connected to the router, download and install this program:
by NirSoft

Finally, if you are unable to retrieve the password(s) by the above methods, then you may need to reset the router to its factory default. Note that this will delete any settings you have made (including administrator password and security key). You would then need to reinstall and reconfigure the router, starting from scratch.

If you can access the web-based settings for the router, you may then reset the router to its default by following the onscreen guidance (see p. 102 of the manual). If you can't access the web-based settings, then you can still reset the router using the physical reset button (see p. 111).. (There should be a small pinhole on the rear of the unit - simply insert a small firm object and press firmly for 10-20 seconds.)

New Modem with a router for wireless Laptop

Some routers have a kind of built in firewall. You need to let the router/modem that it is okay for it to let this information pass through it. Here are your instructions

Follow the steps in this chapter and use the Gateway’s web-based utility to configure the Gateway. This chapter
will describe each web page in the Utility and each page’s key functions. The utility can be accessed via your web
browser through use of a computer connected to the Gateway. For a basic network setup, most users only have to
use the following screens of the Utility:

• Setup. On the Setup screen, enter the settings provided by your ISP.

• Security. Click the Administration tab and then the Security tab. The Gateway’s default username and
password is admin. To secure the Gateway, change the Password from its default.

There are seven main tabs: Setup, Wireless, Security, Access Restrictions, Applications & Gaming, Administration,
and Status. Additional tabs will be available after you click one of the main tabs.

• Setup. Enter the Internet connection settings on this screen.

• Basic Wireless Settings. You can choose your wireless network settings on this screen.

• Wireless Security. This screen allows you to choose your wireless security mode.

• Wireless Network Access. This screen displays your wireless network access list.

• Advanced Wireless Settings. On this screen you can access the advanced wireless features.

• WDS. The wireless distribution system feature is accessed on this screen.

• Firewall. This screen contains filters and the Block WAN Requests feature. Filters block specific internal users
from accessing the Internet and block anonymous Internet requests.

• VPN Passthrough. To enable or disable IPSec and/or PPTP Passthrough, use this screen.

Have you tried configuring the ADSL modem router for the internet connection?
Its possible that since you have changed the ADSL modem router, you may have to configure the ADSL modem router for it to work fine. The configuration depends on what Internet provider you have but you may try these steps for now:

1. Make sure the connections are correct. Connect the computer to the LAN port and the ADSL line to the port assigned for that behind the device.
2. Launch an Internet browser and access and press enter. If a dialog box appears, set the user name as admin and password as zoomadsl and press enter.
3. On the basic setup page of the ADSL router, set the appropriate encapsulation and other settings based on the settings of your provider. If you do not know the settings for your provider, there is a table specified on the user guide for the ADSL router. Here is the link:

you probably need to access the web management function for this modem. Using a PC connected to the modem, open a web browser and type into the address bar the address of the router/modem/gateway. This is usually or or If you cannot find this information, find the status of your ethernet connection on your computer (where it tells you you computer's IP and time connected etc). Here you will find a number labeled "Gateway" this is the number you want to type into your web browser.  Once you get this correct you will be prompted for a username and password (by default it will be admin, admin) then you should have access to the configuration of the modem.
Write back if you're unsure of any steps

No access to set up modem or router

you might have configured your lan settings wrongly.

If your modem was setup for DHCP then you configure your lan to receive IP address automatically, DNS automatically.

If DHCP is disabled on the modem, you have to USE static IP Address for your lan ip and default gateway should be your modem default ip.

the default IP for modem is usually
if DHCP is disabled on the modem the sys ip is

So Configure your LAN setting as follow and Type in the address url.

Lan Settings:
IP Address:
Subnet Mask:
Default Gateway:

click ok.
and type the above url, press enter the modem will ask you for username and password.

Good Luck.

Problems setting up Belkin wireless G+ mimo modem router/usb network adapter

It sounds like the router address is wrong or you are not connected to the network.. Guessing you are using Windows XP or Vista. Go to the DOS prompt ( then type ipconfig. This will bring up details on your network (see example below).

IPv4 Address. . . . . . . . . . . :
Subnet Mask . . . . . . . . . . . :
Default Gateway . . . . . . . . . :

You should see default gateway address which is the address of your router ie in your example. If this is not shown you have not connected to your router properly. If it shows a different address use the address shown to try and access your router. HTH

Vista/router/wireless connection

Make sure that all the wireless cards are set in the properties to obtain an ip address automatically, dissable the wired lan adpter connections as this can confuse the router. Restart all the pc's and then right click on the wireless pc icon in your task bar and then click view wireless networks and make sure that you are connected to your network and that the internet is available, known as local & internet in Vista. open up internet explorer, go to tools, internet options and delete browsing history cookies and temp files and then refresh the page as the proxy server will need to refresh.
