So one computer has full connectivity. The other doesn't. And
you have tried all the previous suggestions, without success.

Approximately 15 months ago, Microsoft introduced a critical
update, which conflicted with the Zone Alarm firewall and led to
the symptoms you are describing. You will find further
information at
http://download.zonealarm.com/bin/free/pressReleases/2008/LossOfInternetAccessIssue.html

You say you have turned off the firewall. However, which
firewall are you using? If you were using Zone Alarm on your
wife's computer, make sure you have updated to the latest
version.

Please also perform the following diagnostic test on both
computers:

1. Re-boot each computer. Also re-boot the router. Then,
make sure both computers have established a connection to the
router.

2. Does your wile's computer still have limited connectivity?
If so, type ipconfig /all from a command prompt on each
computer. (Note - there is a space between 'ipconfig' and
'/all').

3. Post back here with the complete result for each computer
(and indicate which result relates to the computer that has
limited connectivity).

Also, on each computer:

1. Open Control Panel / Network Connections

2. Right click on the name of the device that the computer
uses for its Internet connection - and click on Properties.

3. On the General Tab, select Internet Protocol (TCP/IP) and
click on Properties.

4. Post back here with the detailed TCP/IP settings for each
computer (and indicate which settings relate to the computer that
has limited connectivity to the Internet).

It will be interesting to compare the settings for both
computers. I make no promises. However, significant
differences might explain why one computer has full connectivity
and the other doesn't.



For what it`s worth I`ll list what is currently here:
My computer, working OK:
Physical address 00-90-27-D6-8E-CE
DHCP Enabled Yes
Auto Config Yes
IP Address 192.168.0.4
Subnet Mask 255.255.255.0
Default Gateway 192.168.0.1
DHCP Server 192.168.0.1
DNS Servers 209.18.47.61
209.18.47.62
Wife`s Computer, not working:
Physical Address 00-13-20-80-2F-F7
DHCP Enabled Yes
Auto Config Enabled Yes
Auto Config Address 169.254.231.182
Subnet Mask 255.255.255.0
Default Gateway None
I should point out that right now I get these same figures if I plug the
computer directly into the cable modem - no router involved. Also when this
problem originally started the figures for my wife`s computer were much the
same as mine and I could assign a static address to her computer and get the
message that I had full connectivity but it really didn`t. Now I can`t even
assign a static address. I type but nothing goes in. This thing is really
screwed up. I`m wondering if a repair install of Windows would help?

The IP address for your wife's computer should be in the range 192.168.0.xx. DHCP and auto configuration have been enabled but for some reason, the router has not allocated a valid IP address to your wife's computer.

Most importantly, have you re-booted the router?

You mentioned that you have plugged your wife's computer directly into the modem (no router involved). That might not allow you to connect to the Internet (depending upon the type of connection), because the router needs to allocate an IP address to your wife's computer. Consequently, it would be worth establishing a wired Ethernet connection between your wife's computer and the router, with a further wired connection from the router to the modem.

If you are able to connect to the Internet using a wired connection via the router, then you must look more closely at the wireless configuration.

It is so difficult to guess what has happened, but it seems to me that possible culprits might include:

a) An incorrectly configured firewall, which might still be operating in the background

b) Security software conflicts

c) Incorrect Internet Protocol (TCP/IP) settings. It would be worth checking whether ALL of the settings on your wife's computer are identical to the settings on the computer that works OK.

d) Router configuration, including MAC filtering, password issues, or channel number conflicts with nearby wireless networks

What security software are you using? And have you ever had a Norton or McAfee product on your computer - and subsequently switched to different security software?

One other thought. If one of your friends has a home network, would your friend allow your wife to try her laptop with his/her router? If your wife's computer can connect to the Internet via a different network, that would tell you whether the problem is with her computer or with your Netgear router.
