Wireless problem with host and hardware

I'm about to tear my hair out so hoping i can get some help.

What has happened is i have an already established wireless network here at
home with a host desktop and two wireless laptops. Previously with no
problems.

Now both laptops have lost the ability to connect to the internet and show
no 'internet gateway' connections in network connections. But both are
receiving strong signals from the wireless router. But with the wireless
router not displaying the WLAN led which is always active and flashing whilst
a connection is active, this leads me to believe it is a hardware problem,
where the router is not producing a signal?

I Cannot ping either computers, and the IP addresses are on Auto config and
not assigned, yet both have signals from the router???

Any help on how to test my hardware or perhaps someone can suggest something
else.

Also on a side note, when using the 'set up a home network' wizard when ever
i attempt to assign this host computer to the desktop the wizard freezes??
This has never been a problem, i have no hardware conflicts and no issues
with the host as such.

First of all, if you have a router then you don't have a "host computer". At
least you shouldn't be using Windows Internet Connection Sharing (ICS). All
three computers should be getting their IP's and DNS automatically.
Secondly, it does sound like your router isn't making the connection to the
modem.

To test, remove the cable from the modem to the router and connect the modem
directly by ethernet cable to one of the computers. If you can now surf the
Internet, you know the modem is working.

Then reattach the connection from the modem to the router and the computer
back to the router. Unplug the modem and the router and wait for about 30
seconds to a minute. Now plug the modem back in and wait until all its
lights are on correctly. Then plug the router back in. Testing on the
computer that is wired to the router, do you have Internet access? If not
(and if the WAN light is still off), replace the router.

Just wondering. Have you turned the power off to the router for a good 10
seconds then back on again? Otherwise, it sounds as if your ISP has stopped
your account use to me.

Appologies,

I may not have explained the situation properly,

The wireless router is correctly connected via lan to the desktop with no
problems, the desktop can surf the internet and is getting it's ip address
directly.

The laptops are not, and the WLAN led does not light up or show whatso ever.
Wireless Local Area Network LED. Is there a way i can check the hardware to
find out if it is broadcasting a signal, The laptops can detect a signal
from the router but cannot connect to the internet or attain an ip, which if
i am correct it normally one digit above, the laptops are on autoconfig ip.

The answer is basically the same - power-cycle both the modem and the
router. Swap out the cable going from the modem to the router's WAN
(Internet) port. Does the WAN light come on? If not, then replace the
router.

Hi Chris,

Q1. What type of hardware are you using?

Just a point to note,
Being able to connect to a router doesn't automatically give you access and
allow you to the internet, you still have to be authenticated, assigned an IP
address or allowed static one, and then allowed actual access to the
internet VIA NAT

Q2. Is your Access Point (AP) enabled in your router/modem hardware, either
by IP webpage, or Via your router (Try the MAC Control List section)....?
This will make sure your AP and only YOUR AP has access to your router.

Q3. What is the type of authentication used?? Open, WEP, WPA, WPA2?
Are you using Network Keys for authentication?

It seems to me as though your Router and AP are working fine. It's just the
configuration. Maybe LAN Settings as well on the router, I would say the AP
is not enabled anymore in the router and that is why you have suddenly lost
connectivity.

Router can't give Access Point an IP -> therefore Access Point isn't
allowing clients to retrieve IP from router.

If more clarification is needed, just post back and inform me and i will
follow up

Hope this helps

You sound like you believe your router connected computer should get an IP
number from "Internet" or if you like - your ISP. It doesn't.

From this description, what it sounds like to me is that your wireless
router's AP isn't set on. Go to your router (you need to put its IP address
in a browser to get there) and look inside at the configuration. Have your
router handbook ready, too. Inside it, there is an option for "Access Point"
or "AP" or possibly some other description that means, basically, to turn
WIRELESS actually ON. By default, most devices have this OFF and you need to
set it ON. If you haven't done this then you are getting nowhere wirelessly
and it needs to be on. You get into the router if wireless is off obviously
by a computer connected via a networking cable.

See, if wireless isn't turned on, you can still hook a cable in and use it
but not wirelessly use it and this seems to cover your problem exactly.
