Network did not assign a network address

Hi,

I am trying to coonevt to the internet on a 2nd PC using a Belkin 54g
Wireless Network Adaptor. I have set up home network but the connection via
the Belkin fails with "this connection has limited or no connectivity" The
explanation is "the network did not assign a network address to the computer"
Any ideas/suggestions gratefully received.
Thanks in advance

Not enough info.

What version of Windows/what service pack?
What model router? what model adaptor?
Have you ever been able to use this network? If so, what's different now?
Are there any other PCs connected to the router? Wired or wireless? Do
they connect OK? To Internet? To each other?
How do you connect to the Internet?
Please describe your "network topology" -- for example, DSL connected
to DSL modem; modem connected to WAN port of Linksys WRT54G router; PC 1
connected via cable to LAN port 1 of router; PC 2 connected wirelessly
to router.
Are you using Belkin software or Windows to manage the wireless
connection on PC2?
Can you see the name of your network on the "2nd PC"? Are you sure it's
yours? Did you change the default SSID on your router?
Are you using encryption? Did you try to connect without using
encryption? What happened?

Thanks for reply Lem, hopefully the replies below will help.

What version of Windows/what service pack? - XP , SP2

What model router? - BT Voyager 2091

what model adaptor? - Belkin 54g Wireless Network Adpator

Have you ever been able to use this network? - I used to be able to use
this network, I got a new PC which is now the main PC, the PC I am now using
as the 2nd PC used to be the main PC.

If so, what's different now? (see above)

Are there any other PCs connected to the router? Wired or wireless? Do they
connect OK? To Internet? To each other? -
I also have a laptop which is wireless, connects to the main PC , they both
connect OK, and to the internet

How do you connect to the Internet? Via the BT router (see above)

Please describe your "network topology" -- . for example, DSL connected to
DSL modem; modem connected to WAN port of Linksys WRT54G router; PC 1
connected via cable to LAN port 1 of router; PC 2 connected wirelessly to
router. Are you using Belkin software or Windows to manage the wireless
connection on PC2? -

Main PC is DSL connected to router, 2nd PC is the one with the problem,
3rd PC is a laptop which connects wirelessly. I think I am using Windows
software to manage the wireless connection(do you mean Windows zero
configuration). The questions you ask below I am not sure about

Can you see the name of your network on the "2nd PC"? Are you sure it's
yours? Did you change the default SSID on your router? Are you using
encryption? Did you try to connect without using encryption? What happened?

We're getting closer.

If I understand your answers, you have PC1, PC2, and Laptop. There is
an Ethernet cable from PC1 (the new PC) to your BT Voyager DSL
modem/router. The Laptop connects wirelessly to the router with no
problems.

You have connected a Belkin 54g Wireless Network Adpator (the USB
version?) to PC2. You can't connect to the Internet with PC2.

In PC2, do you have the Windows wireless configuration icon in the
system notification area? See http://tinyurl.com/qjtmp

I will assume you do. When you click on this icon, you should get the
"choose a wireless network" dialog box. See http://tinyurl.com/pvxhg

Is at least one of the entries in that dialog box the name you selected
for your wireless network? Does it say "security-enabled" or
"non-secure"? If you did not select a name when you set up the router,
the name of the network will be whatever BT has set as the default,
probably something like BTVOYAGER2091. The problem with not selecting
your own unique name for your network is that if a neighbor has the same
brand and model of router and similarly didn't change the default, you
may be trying to connect to her network rather than your own.

What happens when you select a network and click "connect"?

Assuming that the above hasn't helped, boot up the Laptop and verify
that it's connected to the Internet. Open
a command prompt {Start > run > cmd.exe [press enter]}
In the command prompt window, type
ipconfig /all [press enter]

What is listed for the IP Address, Subnet Mask, Default Gateway, DHCP
Server, and DNS Servers? Is the setting for "Dhcp enabled" yes?

Now do the same for PC1 and PC2.

Please list the values for all three computers.

Unless you have changed things, the "Default Gateway" for all three
computers should be 192.168.1.1 (which is what I understand the default
IP address of your BT router to be).

The other three computers should have IP addresses of the form
192.168.1.xxx where xxx probably is 100, 101, and 102

Assuming that PC2 does not have a correct IP address, open network
connections, right click on the icon for your wireless adaptor, click
"properties" and select "Internet Protocol (TCP/IP)". Then click
"Properties." On the "General" tab, make sure the radio button is
selected next to "Obtain an IP address automatically."

Ok , here goes Lem. All of your assumptions were correct. Regarding the name
of my network it is BTVOYAGER2091, however I seem to have two, the one which
I am trying to connect is called BTVOYAGER2091-94(security enabled), the
other which is not connected is called -69. When I use WZC for
BTVOYAGER2091-94 it asks for a WEP key which I input using the details
supplied by BT - this works with the laptop.
Now to the troubleshooting you supplied.
The laptop can connect to the internet.
IPCONFIG/ALL for laptop is
IP address 192.168.1.3, Subnet=255.255.255.0, Default gateway,DHCP and DNS
are all 192.168.1.1, DHCP setting is enabled.

IPCONFIG/ALL for PC1 is
IP address 192.168.1.2, Subnet=255.255.255.0, Default gateway,DHCP and DNS
are all 192.168.1.1, DHCP setting is enabled.

IPCONFIG/ALL for PC2 is
IP address 192.168.1.4, Subnet=255.255.255.0, Default gateway,DHCP and DNS
are all 192.168.1.1, DHCP setting is NOT enabled. Please note these were
static settings that I applied when I saw a similar problem to mine covered
in another topic.

Using the above static IP address for the "problem" PC means that I can
connect properly, however when I try to browse the internet I get an error
"cannot connect to the server" . When I try to coonect to MSN Messenger I get
"default gateway is offline".
When I use the "obtain an IP address automatically" I get "limited or no
connectivity" and still cannot browse the internet.

Might be worh mentioning that there is a wireless card installed on this
"problem" PC which I used a few years back, however this is disabled so
hopefully not an issue.

Any more ideas Lem?

I've also just seen Diamontinas reply, given that DHCP is NOT enabled on the
problem PC, is this where the problem lies? How do I go about enabling this?
If you put forward suggestion could you please explain how to action them,
just assume that I know nothing and you wouldnt be far from the truth

Thanks in advance

Pretty sure its not a firewall problem. 3rd part firewall has been turned
off, only firewall protection is via the router and this shouldnt be a
problem, should it?

Hi

As a first step connect to the Router via a Wired computer, read the Router's
manual and configure the Router's LAN side as it should. Put every thing on
default. Make sure that DHCP is enabled, and switch Off the Wireless
Security.

At this point, if the Wireless computer would not connect at default without
security.

Read this, http://www.ezlan.net/wireless.html

Check the Network configuration of the computer.

In General, you can debug the Network Settings of a computer by following
these steps.

Check the Network parameters in the Computer's Device Manager. Make sure
that the Network Card drivers are installed correctly; i.e. there is No IRQ
conflict, and No Ghost installation. http://www.ezlan.net/faq#ghost

Step Two Verify Basic network setting in the OS:
http://www.ezlan.net/Installing#verify If the above two Steps indicates that
every thing looks good but functionally it does not work.

Step Three. Check (and repair if necessary) the Socket Layers, Winsock, and
or refresh the TCP/IP Stack. http://www.ezlan.net/clean#refreshnet

When working well secure the wireless.

For info, at the moment the setting is "obtain an IP address automatically".
IPConfig/all shows that the autoconfig IP address is 169.254.224.28, Subnet
Mask is 255.255.0.0, the default Gateway setting doesnt show anything, eg is
blank.

Jack, thanks for the reply but these tips either didnt work, or more to the
point didnt make much sense to me
The router is already connected to a wired computer with no problems, it is
a BT modem/router so came fully configured and without a manual. I do not
know how to put everything on default, or how to switch off Wireless
Security. I uninstalled an obsolete wireless card from the problem computer
but still no joy. I disabled all anti virus/firewall etc on this PC , still
no joy.
I cannot repair the socket layer etc as I do not have a portable USB. Sorry
and thanks!

I don't understand what you mean when you say that setting a static IP
of 192.168.1.4 allows you to "connect properly" but not to browse the
Internet. What makes you think that you're connected?

The fact that the laptop can successfully wirelessly connect and browse
the Internet (it can, can't it?) means that that the router's DHCP
server is ON and that your DSL connection is working. In any case,
you've already tried Diamontina's next suggestion to set a static IP.
There's nothing wrong with setting a static IP, and some (e.g.,
Diamontina) prefer to have small wireless networks use static IPs.
Usually, one sets all the IPs statically, but that's not necessary as
long as you ensure that any static IP is not the same as an IP assigned
by the DHCP server. In your case, at least for now, your're OK with
using 192.168.1.4.

The fact that you can't connect and browse from PC2 could have several
causes:
-- firewall (I know you said you checked, but check again)
-- some other security setting on the router, such as MAC restrictions
or IP restrictions
-- security/encryption problems

I couldn't find anything like a user guide for the 2091 at BT's website
(I assume the 2091 is a 802.11(g) rather than .11(b) router), but I did
come across this review site with a few screen shots.
http://www.adslguide.org.uk/hardware...oyager2100.asp

Being careful not to change anything you don't understand, log in to
your router's "control panel" by entering 192.168.1.1 (or
http://voyager.home) in your browser. Click on the "Advanced" button,
and then click "security." Is IP filtering enabled?

Then click the "wireless" link. Assuming it's like the one linked
above, you should see the "Wireless Network Name (SSID)" box with a name
filled in. I'd change this to something that's more
personalized/recognizable by you, but if you do so, you'll have to
reconnect to the new SSID with your now-working laptop.

Click on the "MAC Address Control" link at the top of the Wireless
Configuration screen. Is access control ON or OFF? If it's ON, and you
want to keep it ON as added security, click the "View Access Control
List" button. You should be able to add the MAC address of PC2 (which
you can find by running ipconfig /all on PC2 -- the MAC address is
what's called there "physical address."

Click the "encryption" link on the Wireless Configuration screen. I
find it improbable, but because your Voyager apparently came with
encryption pre-configured by BT, it's possible that they provide the
same default key to everyone, and that you are, in fact, connecting to
your neighbor. This is unlikely, but you might want to turn encryption
OFF while you are trouble shooting. Be sure to turn encryption back
on. Of the various types of encryption available, WEP is the weakest,
WPA, the next, and WPA2 (if available) the current strongest. Use the
best encryption level that is compatible with all of your wireless
equipment (it's a least-common-denominator kind of thing).
