Hi does anyone have any ideas before I run out and get a
new network card how to go about checking it?
I have only one Desktop PC here and can get no Internetn
access through it.
XP recognises the card and if I ping it I just get the
assigned IP address I don't see the ADSL modem/router it
is connected to.
XP says the card is working fine and no issues, any ideas?

Cheers Pol
 
Is modem/router turned on? Can you ping 127.0.0.1 ?
Do you have a firewall? Have you checked with the router
setup FAQ on the router/modem website?

That is what manufacturer diagnostics are for. Any decent
computer manufacturer provided comprehensive diagnostics for
free. However if yours is a computer bought only on price, or
if the network was added after market, then you must get the
NIC's comprehensive diagnostics.

Diagnostics first test interface between motherboard
computer and NIC computer. Then a data exchange test between
NICs is run (that far exceeds what can be tested by Windows);
but only if both computers have NIC from same manufacturer.

After hardware is confirmed by a diagnostic (that does not
use Windows), only then fix Windows to talk to that NIC.
Notice the concept. Break problem down it separate parts.
Test NIC hardware without the unknown called Windows. First
test communication from CPU to NIC. Only then test NIC to NIC
hardware (the cable, router, etc). Assume nothing. Only when
all hardware works are you then ready to verify software
(Windows and NIC driver).

In addition, each NIC and router has a light that indicates
it is receiving a signal from the other end of cable. A light
must be on for each end of cable - else cable (or hardware
port) is defective.

XP has one other advantage that can ID a problem early.
Locate and learn the Device Manager. Use Windows Help if
necessary. If Windows has no problem with hardware, then the
NIC will appear in list without any yellow explanation point.
If Windows has a problem with the NIC, then the above is
necessary to isolate the problem to either hardware or
software.
 
What is the card's assigned IP address? Who assigned it? Was it you or
the router's DHCP server? The main question is whether or not you can
ping the router from your PC? If so, everything is hopeful. If not,
the network stacks on the two devices are not talking either because
a)the IP addresses are incompatible (effectively on different networks),
b)the cable is incompatible/bad, c)the router is dead.

As long as you can ping the router from the computer, you can go into
the Internet Options control panel and use the setup wizard to set the
LAN connection as the source of your Internet connection (click the
"Setup" button at the top of the "Connections" tab).

If you can't ping the router, open the properties of the LAN connection
(Network Connections control panel) and under the "General" tab find the
"Internet Protocol (TCP/IP)" entry. Highlight it and click the
properties button. Click the "Obtain an IP address automatically"
button. Click OK to all windows. This will, of course, only work if
there is a running DHCP server in your router.

Type ipconfig in a command window to see the IP address, netmask and
default gateway which should be the IP address of your router.

I hope this helps.

Jack
