First inform your ISP and ask them to check the condition of your modem, also ask if dns addresses have been changed or any other settings that they might have changed. They are duty bound to do this. If their report is that everything is ok from their end, ask them to do the same at your end too. Only after that decide on buying a new modem.....sodeep

Cannot connect to DLink DIR-655


The part below is all you need to look at, the rest is Ethernet which is your wired connection, ethernet card.

Here is what are causing your problems from what you gave me and basically your computer is not communicating with the router:

1)I don't see any IP address for your laptop so you can't get on the internet if you don't have an IP address, also, I don't see any gateway address. The gateway address is your router address, and that address is given to the router automatically from your Internet Service Provider.

So if your computer cannot see the gateway address then the gateway address (router) cannot give you an IP address to get on the Internet.
Your Wireless card looks ok, that is the physical address and if you were able to do the loopback then its working.

So on your laptop I would begin from the beginning. Go into network connections and delete the DLink connection if it is there. Then Start>control panel>Network connections>click wireless network connection>click change settings of the connection on the left window>click wireless network tab>make sure checkmark"use windows to configure my wireless network settings>click add a new network>TYPE IN THE SSID FOR THE NETWORK>ENTER WEP/WPA KEY>CLICK OK, then close and you should be connected.

You said other computers are able to access the internet thru the DLINK so it all points to your laptop not being configured correctly.

HOWEVER :)...I see alot of "Media disconnected in your list. Make sure all of the lights are working on the front of the router, if not check the cabling or call the ISP sometimes the problem is on their end. Hope this helps, keep me updated.

How to Share your Internet Connection through laptop's WLAN(Wifi) card?


Every Windows Operating System after Windows 98 can share its Internet Connection using this Technique. Microsoft defines this technique as Internet Connection Sharing (ICS). But setting ICS is very obscure to most of the users. This comes very useful if you live with your roommates and you guys have single internet source like a USB modem Connected to one laptop only. Using Internet Connection Sharing(ICS) that laptop can Broadcast its Internet to other laptops in the room. Technically, the range of a laptop's WLAN adapter is around 20-25 meters. So it can easily handle near by rooms also. This can also be done with a PC having a WLAN card.
To setup and broadcast your internet it is mandatory that you are accessing internet using anything other than Your WLAN card like a USB modem, Ethernet etc. This is because your Wireless adapter(WLAN) will be used for Broadcasting your Internet connection to your friends.
Server laptop:- Laptop with Internet Connection.Client Laptop:- Laptops accessing the internet of server laptop.
Follow the steps to share your internet connection..here it goes:--0b73509.gif
  1. Open the "Control Panel" of the laptop that is accessing Internet and go to "Network and Internet" then "Network and Sharing Center".
  2. On the right side of the "Network and Sharing Center" click the "Change Adapter Settings" and you will see all the available network adapters in your laptop.
  3. Now Right-Click the adapter through which you access internet and click "Properties" option. The properties window will open.
  4. In "properies" Window click the "sharing" tab check "Allow other network user to connect through this computer's Internet connection"97ac799.jpg
  5. In the sharing tab, Select "Home networking connection" type as "Wireless Network Connection" click "OK" and select "Yes" to the Confirmation warning. see above image.
  6. Now Right-Click the "Wireless Network Connection" in "Change Adapter Settings"and Open Its Properties.
  7. In "Wireless Network Connection Properties" Double-click the "Internet Protocol Version 4(TCP/IPv4)" and select the "Use following IP address"
  8. Enter the IP address as "192.168.000.001" and "Subnet mask" as "255.255.255.0"
  9. Leave all other fields blank in Server laptop, which has access to internet.0219162.jpg
  10. Now setup a wireless "ad hoc" computer to computer connection using "setup a new connection or network" in "network and sharing center" and Name it as anything like "Internet_sharing".c2debe7.jpg3a69972.jpg
  11. Now bring other laptops that will use the Shared Internet connection.
  12. Open "Change adapter Setting" (Described in step 2).
  13. In "Change adapter settings" Right-click "wireless Network Adapter" and Click its properties.
  14. In "Wireless Network Connection Properties" Double-click the "Internet Protocol Version 4(TCP/IPv4)" and enter following IP address:-
  15. IP address-"192.168.000.002", Subnet mask "255.255.255.0", Default gateway-"192.168.0.001" and Preferred DNS server: "192.168.000.001".
  16. Use the same step from 11 to 15 to connect other laptops and Increase the IP address by +1. Ex- 192.168.0.3, 192.168.0.4 & so on. Rest of the settings like Default gateway etc will be same on all laptops. Only the server laptop will have blank entries in these settings.
  17. Now connect all the laptop with the Wireless network(ad-hoc) named "Internet-sharing" that you had previously broadcasted in step 10 in server laptop.
  18. Now in the server laptop, disconnect and then reconnect the internet connection(This is a necessary step for Internet Connection sharing(ICS) to work).
  19. Now access internet in all laptops...ENjoy.
Note:- For Advance Users.. this information is necessary only--The IP address of server laptop work as the "Default gateway" and Preferred DNS server of Client laptop and on server laptop these fields are blank. Use same series of IP address as used in the server.

Cant connect to the internet.


Click on Start and type CMD. Open CMD and type ipconfig. Check out the IP address V4 for the Local area ethernet adapter or wireless area adpater depending on wireless or wired connection. Any ip address other than of the class 169.254.x.x shoud be considered good. If you have an IP address is any other number other than the above you have a good IP address. to test the internet connectivity type PING www.google.com. If the results are Packets sent 4 Recieved 4 Lost 0 then the issue could be due to Internet Explorer bing corrupt or a firewall blocking the internet access. Power off the computer. Power on the system and as soon as you see the Dell logo please tap the F8 button 3 - 4 times. You'll get to teh Advanced Windows boot option screen. Select safe mode with networking and see if the internet works in the safe mode. If yes then it could be the firewall. Uninstall you antivirus and check.

Network did not assign a network address to the


Hi there, the only reason it doesn't work it's because the wireless key is not correct. It usually shows limited connectivity when the wireless key is not correct. Even just a letter upper or lower case will cause the problem. Since you are connected with the other computer go under the Router settings and double check the wireless key. Check what kind of encryption the router is using, make sure your wireless adapter can support it.

No Internet Connection


Hi kathy

I believe you are connecting to the internet using wireless. Are you using this laptop to connect to a home wireless network or you connect using a cable. This will be a good way to analyze your problem

Post the ip address that you are getting.
You can get the ip by
start -run-type cmd enter
you will be in the black command prompt
just type ipconfig
and let me know what you get under ip address.

Also let me know the wireless router, your Internet Service Provider and also how many systems are there are at your home if you are connecting to a home wireless network.
Also let me know which is firewall or antivirus program that you have.

thank you do let me know if this works and do share your experience.

thank you

Dell Dimension DE051:Wireless Internet Problem (Can't Load Sites)


contact Comcast and have them reset your IP address. also have them ping your modem after they reset IP.
Also, see Linksys website for LELA (easylink advisor) to add devices to network. Uses a good bit of memory so don't allow to run automatically at start up.

Internet sharing


Hi, Could be done. On the Dell XP - 1. Activate your Internet Connection Sharing. Go to Control Panel, Click on Network Connections, right click on your Local Area Connection, Properties, Advanced tab, check Allow other network users to connect through this computer's internet connection. In Home networking connection, choose "Local Area Connection", OK; 2. Back to General settings, click on Internet Protocol (TCP/IP), click on Properties, tick Use the following IP address: IP address 192.168.0.1, Subnet mask 255.255.255.0, Default gateway 192.168.0.1, if you know ITT DNS use them otherwise tick "Obtain DNS server address automatically." You have to connect the DellXP with the DellVista using a crossover networking cable. On the Dell Vista- 1. In your Network Connections, right click on your Local Area Connection, Properties, click on Internet Protocol (TCP/IP), click on Properties, tick Use the following IP address: IP address 192.168.0.2, Subnet mask 255.255.255.0, Default gateway 192.168.0.1, if you know ITT DNS use them otherwise tick "Obtain DNS server address automatically." The above method will also work with peer to peer wireless networking. It might also facilitate connection if you enable auto-detect proxy settings in your browser. There are other methods. This is also better explained at Microsoft support Hope this be of help/idea. Post back how things turns up or should you need additional information. Good luck and kind regards.
