Re: dell will not connect with internet
Using another PC, download MEMTST86 from memtst86.com follow directions to burn it to a CD. Run overnight in your Dell. If you have two memory modules, try removing one then the other and see if the problem goes away. Sounds like a hardware problem.

Locate the key on the wireless internet setup router, and be sure that your computer is using the same key, in order that it connect to the router properly. Another suggestion is to use the MAC address - a unique to each piece of computer gear - and register the MAC Address from your Dell in the table of the router, such that no other computer, unless registered with the router in that way, can gain access to your WiFi.It is actually more secure than using encryption, since only one device can have a MAC address of each type. They are unique in all the computer world. Like a fingerprint.
As long as the router has wireless antenna's on it or indicates it is a wireless model then all you need to do is turn on the wireless function of the router. You do this by access the router, open a web browser and try either http://192.168.0.1 or http://192.168.0.100 one of those should be your router. Log in and go to the wireless settings. There you can enable it and configure it.
From there, as long as your laptop has a wireless network card built in, it will see the wireless network and you can just connect to it...
If your running xp, make sure the netowrk card is not disabled, make sure you rnot using a cross over cable. use the cable you got with the routers. Try reinstalling the network card, goto dell support andenter you model to get the drivers.
1 thing to check. goto start ,control panel. double click on netowrk conections. right click on the main conection witch is the card in your pc, goto properties. andin the list internet protocol (tcp/ip) click this. and pres properties.
make sure in here obtain ip addres is automatically. and obtain dns is auto too.
You need to configure MAC cloning for your router to use the MAC address of the desktop PC if the router supports this. If not, then you'll need to change routers or continue to put up with the inconvenience.
For some reason(power glitch or failure possibly), your router is re-starting or resetting and apparently by default presents the first MAC address it sees to the ISP. The ISP apparently has registered your desktop MAC and only recognizes it and this is why you need to clone it.
try to plug all the connection as it was before, then you will be able to access your wireless f router via web based control panel and from there you will be able to configure the settings, if its automatic or you have to set as static, it depends on the modem, if the modem requires you to dial up for the connection so that the router may be able to read the connection and you will start to have the internet connection as soon as the modem reads the router through this setting, the web access by default is 192.168.1.1 and the defaul username would be admin and password is admin.
hope thi help you out, if theres anything you need to ask just send me question...
I suspect your cable modem is looking for the MAC address of your compaq's NIC. if you run IPCONFIG /ALL on the Compaq (Start run, cmd <enter> then IPCONFIG /ALL <enter> , you can get the 12 digit MAC address.
In the router setup, there should be an option to CLONE MAC address, put in the MAC address of the COMPAQ. Then release and renew the IP address in the Router from the cable modem. The router should then get a valid IP address from the cableand you should be able to connect both systems to the router and surf.
Does it say limited connection to network? You're connecting it through a wireless router right? Do you see your wireless router when you search for networks? I had similar problem with my previous Dell laptop. Wireless use to work untill one day it just stopped, found the networks, but kept giving me limited connection whenever i tried to connect. I found out the problem is linked with the driver. Dell laptop i had was also on XP OS. Maybe try reinstalling the drivers. After I formatted my computer and reinstalled drivers, it started working again. Hope this helps.
Choose a convenient location to
begin installing your router such as an open floor space or table. This
does not need to be the permanent location of the device. Particularly
for wireless routers, you may find it necessary to re-position the unit after installing
it as the cables / signals may not reach all areas needed. At the
beginning, its better to choose a location where it's easiest to work
with the router and worry about final placement later.
Plug in the router's electrical power source, then turn on the router by pushing the power button.
(Optional) Connect your Internet modem to the router. Most network modems connect via an Ethernet cable but USB
connections are becoming increasingly common. The cable plugs into the
router jack named "WAN" or "uplink" or "Internet." After connecting the
cable, be sure to power cycle (turn off and turn back on) the modem to
ensure the router recognizes it.
Connect one computer to the router.
Even if the router is a wireless model, connect this first computer to
the router via a network cable. Using a cable during router
installation ensures the maximum reliability of the equipment. Once a
wireless router installation is complete, the computer can be changed
over to a wireless connection if desired.
Open the router's administration tool.
From the computer connected to the router, first open your Web browser.
Then enter the router's address for network administration in the Web
address field and hit return to reach the router's home page.
routers are reached by either the Web address "http://192.168.1.1" or
"http://192.168.0.1" Consult your router's documentation to determine
the exact address for your model. Note that you do not need a working
Internet connection for this step.
Log in to the router.
The router's home page will ask you for a username and password. Both
are provided in the router's documentation. You should change the
router's password for security reasons, but do this after the
installation is complete to avoid unnecessary complications during the
If you want your router to connect to the Internet, you must enter Internet connection information into that section of the router's configuration (exact location varies). If using DSL Internet, you may need to enter the PPPoE username and password. Likewise, if you have been issued a static IP address
by your provider (you would need to have requested it), the static IP
fields (including network mask and gateway) given to you by the
provider must also must be set in the router.
If you were using a primary computer or an older network router to connect to the Internet, your provider may require you to update the MAC address of the router with the MAC address of the device you were using previously. Read How to Change a MAC Address for a detailed description of this process.
If this is a wireless router, change the network name (often called SSID).
While the router comes to you with a network name set at the factory,
you will never want to use this name on your network. Read How to Change the Router SSID for detailed instructions.
Verify the network connection is working
between your one computer and the router. To do this, you must
confirmed that the computer has received IP address information from
the router. See How to Find IP Addresses for a description of this process.
(If applicable) Verify your one computer can connect to the Internet properly. Open your Web browser and visit a few Internet sites such as http://compnetworking.about.com/.
Connect additional computers to the router as needed. If connecting wirelessly, ensure the network name (SSID) of each is computer matches that of the router.
Finally, configure additional network security features as desired to guard your systems against Internet attackers. These WiFi Home Network Security Tips offer a good checklist to follow.
connecting devices with network cables, be sure each end of the cable
connects tightly. Loose cables are one of the most common sources of
network setup problems.
What You Need:
A network router (wireless or wired)
Network adapters installed on all devices to be connected to the router
A working Internet modem (optional)
A Web browser installed at least one computer in the network
