How can I find router I P address & password

Well it depends what ip address you are looking for - if you are looking for the local ip address all you have to do go is go to the command line and type in "ipconfig" without the quotes. What you are looking for is the gateway address.
If you are looking for the ip address the rest of the world sees it will be a little more tricky. The first thing you are going to want to do is log in to your router. You can do this by opening your web browser and in the address bar typing the local ip address of you router. (It should be
You will be prompted with a log in box. The default username is admin and the default password is password. If you cannot log in using these credentials and do not remember if you have changed the password all you have to do is get a small pointy object (pen, paperclip, pin etc). Look on the back of your router for a small hole that says reset on it and push it in for 30 seconds. This will reset it to factory default settings - if you are wirelessly connected to your router you will have to reconnect to the network it will be called netgear most likely. You can then log in to your router.
Once logged into your router click on the "Maintenance" heading on the main screen then select "System Status"
Your IP address will be listed under the "Internet Port" heading.

Cant access to my D-link wireless access point to creat a wep key..what i wana do?

2. Go to
3. Download and install pingplotter. The free version.
4. Run ping plotter to determine the IP address of your router. Click on and click on trace. Your router will be the FIRST IP address listed.
5. Write the IP address down. If it is not someone has already configured the router.
6. Log in to your router using a wired connection with the IP address you wrote down. (if you cannot do this due to fthe router being pre-configured by your Internet Provider or other problems, you can force your router to reset to the factory defaults and configure it yourself.

6a. Use a straightened paper clip or similar object to force the router to reset itself to the factory defaults. Put the paper clip in the reset hole next to the WAN connector on the router and hold it for 10 seconds. This will force reset your router.
7. Remove the power from your router for at least five minutes. This will cause your IP to reset his connection to your router.
8. Log back in to your router using a wired connection.
9. The default D-link IP address is The D-link default user name is admin. The password is blank. No NOT blank, just enter nothing but the user name and click on the next button.

Unable to connect to internet

The IP address you use with your browser is not to get into the Dlink WEB page, it is to get into the DLink router configuration, to set up the router and wireless security eg. network SSID, turn off SSID brocast, WEP/WAP encryption, MAC address filtering etc.

Cannot log on to dwl2000ap

If the SSID changed to the default then you know that the router reset to the default settings and you should set your computer to automatically get its IP address via DHCP. I always set up my routers through a Wired connection first, just to setup the router and then go with the wireless. The default for the router should be and subnet . If the computer is set with a static IP address, change it to obtain an IP address automatically or the network card will not bother even looking for an address.

Router unable to acquire ip address

You're not telling us much. What's the OS and what have you tried? Wired or wireless? This problem is usually solved by resetting the router to defaults and starting over, following the directions carefully.
