Diabled wireless connection will not enable again, why?

My computer: Custom made, Intel P4 mainboard with Intel 1.8GHz CPU and 512MB
Ram. Operating system is Windows XP Home Edition with Service Pack 2.

To install a new wireless printer software, I turned off windows firewall
and to remain safe, I shut down my Netgear wireless internet connection
(Currently without WEP encryption). But, whereas I normally go to the
Netgear utility and apply a profile of 'none', which always has worked, this
time I was on the Network Connections page and right clicked on the Wireless
Network Connection, then clicked 'disable'. Before doing anything further
with the printer, I needed to access my email account, so, I again right
clicked on the Wireless Network Connection, then clicked 'enable', but the
condition changed to 'Not connected' with the red X in the picture and the
tray icon. I also clicked 'repair' to no avail. No other changes were made
but now I cannot access the internet. What happened?

Quickest and easiest since you haven't yet installed the printer - do a
System Restore to before you did whatever you did.

Then when you want to install the printer leave the Windows Firewall alone.
If this is an HP printer, it will give you prompts to allow access through
the Firewall anyway. Besides, you are behind a router. No need to turn off
the wireless network adapter anyway.

Not enough info. Are you running under Zero Config?
If not, you should have access to your adapters
control panel, showing the state of your connection,
or lack of it.
Try
Start -> All Programs -> Accessories -> Command
Prompt -> Enter
then type ipconfig /all followed by Enter and report
what it says.
If you put a space after /all folllowed by

Have you tried a restart from power off?
Might well fix it.
If you have access to XP Admin account
then XP has a lot of built in diagnostics.
Like the dreded yellow exclamation mark against
the adapter and various logs that collect error
messages.

Thank you, Malke, for your response. Yes it is an HP printer and having
read further about the installation, screens do show up if there is a
firewall in the way; so I will cross that bridge after I correct my current
problem.

As to my Netgear, I have always shut it down when I was not on the internet,
thinking that provides additional protection. I do understand that the
router itself is firewalled, but does that offer total protection?

Concerning 'restore': I keep that turned off now because although I have
used it in the past several times, the last time I used it, an error occurred
and the system locked up. Luckily, I had backups of my most important data
because the only solution was to reformat the hard drive, reload all
programs, and then recoup the data.

So, somehow, I need to figure out what happened here and correct it. I have
uninstalled Netgear and reinstalled it as well as the XP operating system.

I'm not familiar with Zero Configuration, although I have read that it is
under Administrator Tools somewhere which I don't know how to access. I do
have access to the Netgear control panel which will show signal strength of
100%, but will not connect.

I will try what you have suggested, save it to a file, and report it here;
but, I will have to get back to my computer first, which is not here. Also,
I work nights and need some sleep, so will be reporting tomorrow morning.

Yes, I have powered off and restarted which did not fix the problem.

I am the XP Administrator on my system but cannot claim knowledge of XP
diagnostics.

Completely unnecessary to shut down the router. Leave your cable/dsl modem
and router on. The router provides a simple form of protection by using NAT
- Network Address Translation. This (simply) means that the router gets a
public IP address from the cable/dsl modem on the WAN side and then assigns
private IP addresses on the LAN side. A private IP address (192.168.x.xxx)
is invisible from the Internet. You still need a software firewall on the
computer, but you'll be fine installing your printer.

Leaving System Restore off isn't the best decision as you can now see. A
better thing to do is to determine why you were having difficulties with it
and what was really wrong with your computer. System Restore alone would
not be responsible for the problems you experienced. However, that's as may
be since you don't have it on and the easy fix isn't available to you.

I'm honestly not sure what you did or why you felt you need to totally
reinstall Windows. A shotgun approach to a technical problem that really
requires microsurgery makes it very hard to troubleshoot.

Here are a few things to try:

1. Connect your computer to the router via ethernet. Can you get online? If
not, unplug the cable/dsl modem and the router. I'm talking about their
power connectors. Wait about 30 seconds and then turn on the cable/dsl
modem and then turn on the router. You should be able to get on the
Internet now.

2. Assuming that you are now on the Internet, go to the router's
configuration screens and check your wireless settings. Make sure the SSID
is named something other than the default. Check that you have set your
encryption correctly and that you know the key.

3. Now go to your computer. Since you reinstalled Windows, did you also
reinstall all the hardware drivers? If not, you need to do this. If you
have cd's that came with the computer, use them. Otherwise you will need to
go the device mftrs.' websites for your motherboard, video, audio, etc. If
you did not install the hardware drivers, I would uninstall the wireless
network adapter until you did, and then install the adapter again
afterwards. Make sure you check "show hidden devices" in Device Manager and
remove any "shadow" wireless adapters, too.

4. Remove the ethernet cable and see if the wireless card picks up the
signal from your router. If it doesn't, try a different wireless adapter.

Post back with results of your troubleshooting or if you have any questions.
As I said, it's hard to untangle what you've done and naturally I don't
know the state of your system. If all this seems too much, then have a
local professional come on-site and straighten you out.

This bit looks a bit iffy.
IP addresses snould be of the form nnn.nnn.nnn.nnn
No default gateway and no DHCP
Conclusion it can't connect, which we know.
Usually after the USB adapter you get something like,

to static addressing so the DHCP entries changed..
