Hi, try to disable or reinstall your modem, then reenable it, see if you have dinamic DNS or DHCP on. or you have static ip?
check your router too.

Dell pc wont pick up internet


There are wide issues that may occur, with a issue with "dell pc wont pick up internet" is very general, so please be specific, however i went over most issue step by step, hope this help
Make sure you have the correct IP scheme for your network. This would include the:
IP Address
Subnet Mask
Default Gateway
DNS Servers
Click on start, run, type in cmd, The run IPCONFIG /ALL. A sample where a router is used is in the following graphic.
IP Address:
If you have a router, common examples would be:
192.168.0.x, 192.168.1.x or 10.0.0.x
If you are directly connect to your DSL or Cable Modem, you should have an IP address that would correspond to something from your ISP.
What you don't want to have is something like 169.254.x.x. This means you are not getting and IP address assigned and needs to be resolved first.
Subnet Mask:
Also make sure you have the correct Subnet Mask. Most commonly this would be 255.255.255.0
DNS Servers:
Make sure you have the correct DNS Servers.
Sometimes this is the IP address of your router, so it would be the same as the Gateway IP.
Sometimes (as in this example), it is the actual DNS servers used by the ISP.
Possible causes for not getting an IP address assigned are:
1. Defective cable, network card or port on the router. Make sure you are using all known working components.
2. Your router is not configured for DHCP (which would automatically be assigning IP addresses).
This and can be done from that same command prompt you used to run IPCONFIG
2. Try pinging the router's IP address
e.g. ping 192.168.1.1
If you get a reply, then your connection to the router is working.
If you don't get a reply, then you need to double check your network card, cable, port on the router. You might also see if any other computers on the network can do the same.

3. Try pinging an external site by IP address
e.g. ping 4.2.2.1
If you get a reply, then you have a connection to the Internet.
If you don't get a reply, there are several things you can try:
1. Double check that the router is connecting to the Internet. Typically you can access the router through your web browser and check it's status.
2. Take the power off your DSL/Cable modem and Router. Plug the modem back in a wait a minute or so. Plug the router back in and wait a minute or so. Then restart your computer.
3. WINSOCK Fix - It is possible that the WINSOCK Registry entries have gotten corrupted. This is getting to be a more common problem. See WINSOCK FIX for clean ones you can download

4. Try pinging an external site by Name
e.g. ping www.yahoo.com
If you get a reply, then you have a connection to the Internet and DNS is working
If you don't get a reply, there are several things you can try:
1. Double check your DNS entries
2. You many need to use the same DNS IP address that your ISP or Router is using.
3. On rare occasions your ISP has problems with their DNS servers. But that is rare in comparison to misconfigured computers.

If your PING tests work but you are having problems browsing sites on the Internet
1. If you could ping external sites by both IP address and Name, but cannot browse the web, likely your web browser is misconfigured.
2. Double check that you don't have an incorrect or not needed Proxy server assigned.
For the Internet Explorer - Tools / Internet Options / Connections tab / LAN settings button. Uncheck both Automatically detect settings and Use a proxy server for your LAN.

Internet connection problems


Troubleshooting Internet Connection Problems The purpose of this section is to give general tips
on troubleshooting your Internet Connection

While there are many possible configurations, I'll try and cover the most common ones.

Making Sure You Have Correct IP Information
Basic PING Tests
Browser Configuration

Making Sure You Have Correct IP Information 1. Make sure you have the correct IP scheme for your network. This would include the:
  • IP Address
  • Subnet Mask
  • Default Gateway
  • DNS Servers
2. There are a few ways you can see what IP addresses are being assigned.
But generally for:Win9x - Start / Run / command
Windows2000/XP/Vista - Start / Run / cmd
The run IPCONFIG /ALL. A sample where a router is used is in the following graphic.
ipconfig.jpg 3. IP Address:
If you have a router, common examples would be:
192.168.0.x, 192.168.1.x or 10.0.0.xIf you are directly connect to your DSL or Cable Modem, you should have an IP address that would correspond to something from your ISP.
What you don't want to have is something like 169.254.x.x. This means you are not getting and IP address assigned and needs to be resolved first.
4. Subnet Mask:
Also make sure you have the correct Subnet Mask. Most commonly this would be 255.255.255.0 5. Default Gateway:
Make sure you have the correct Default Gateway IP address.
With a router, this is typically the IP address of your router. 6. DNS Servers:
Make sure you have the correct DNS Servers. Sometimes this is the IP address of your router, so it would be the same as the Gateway IP.
Sometimes (as in this example), it is the actual DNS servers used by the ISP.
7. Possible causes for not getting an IP address assigned are:1. Defective cable, network card or port on the router. Make sure you are using all known working components.
2. Your router is not configured for DHCP (which would automatically be assigning IP addresses).
But you need to have this correct before proceeding.
Basic PING Tests 1. This and can be done from that same command prompt you used to run IPCONFIG 2. Try pinging the router's IP addresse.g. ping 192.168.1.1
If you get a reply, then your connection to the router is working.
If you don't get a reply, then you need to double check your network card, cable, port on the router. You might also see if any other computers on the network can do the same.
3. Try pinging an external site by IP address e.g. ping 4.2.2.1

On computer it says I have a good connection but I cannot get onto internet. when I turn modem off, wait, turn it back on, I can get connected temporarily but it doesn't last. calls to comcast say they...


When you lose connection open a command window and Ping the router- modem IP address. If you get a reply yr network is good. Then ping an outside address, such as 74.125.53.104
If you get a reply then yr problem is likely to be with DNS. Go to yr network settings and specify a DNS such as 208.67.222.22

Unable to connect with dlink300 router


You must configure first its settings both on your network card and router. See you manual.

First you must connect your internet directly to the computer then get its DNS settings, jot it down. Then connect the router lanport1 to lan card port of your computer using LAN cable. Under lan properties goto TCP/IP settings input the default IPaddress 192.168.0.1 of the router then its subnet mask commonly 255.255.255.0, the router's default gateway, input the DNS settings of your ISP 2 of the set.

Then goto default router's utility web. Open internet explorer, key in router's ip add 192.168.0.1 you should go to router's configuration log in user = admin, pass = just hit enter. Set your time and date then save. You could also test its connection by pinging the IP address of router. on windows DOS. Type ping 192.168.0.1 you should get 4 lines.


If everything is set. Connect the internet cable(UTP/LAN cable) to its WAN port of the router then test to browse the internet. If not then change the DNS settings with the remaining set (on Lan setting).

If I miss something just leave a comment.

Check out your internet connection and its settings, whether it is dial up or broadband oriented.
then you have to know about your ip address of dns server in the network setting places.

ping 10.10.10.5 and press enter key.. this is the sample ip address only. if it gets reply, your dns server is ok. you can use internet. suppose, it wont comes, ask your service provider or support for another or different ip address of dns to check it out.

ADSL modem, firewalls


What did you have her ping an IP Address or a domain name?

Was she attempting to ping the gateway address on the lan side of this adsl device? In that case either DHCP is not supplying a dynamic IP address or the static IP address, subnet mask, default gateway address configuration in her adapter is incorrect.

If she pinged an IP Address and it is not the prior issue I would favor that the modem side of the device are not set properly for her internet service provider. The ISP's support/help website may help in determining the correct values here.

If she pinged a domain name like www.google.com then it could be the same as either of the above or it could be a lack of DNS addresses in the router or her local adapter configuration whereever they are preferred in her environment?
