Problem with Limited or No Connectivity on Wireless Lan Network

[nightflame1982]

Hi

I've been facing a problem with my wireless lan and I hope that
somebody might be able to help me out.

I'm using a Belkin Wirless Card on my Fujitsu laptop. Even though I've
entered the right WEP code, the status screen shows that there is
"limited or no connectivity" in terms of the connection. The signal
strength is excellent.

I tried repairing the network status, but the same error message still
appears. I've also tried shutting down the firewall as well as
unchecking the "Enable IEEE 802.1x authenticatio" tab but to no
avail.
When i check the details it does not show the IP address, DNS Server
No and default gateway.
Upon checking the ipconfig command under command prompt , the IP
address starts with a 169.254.XXX.....I understand that if you are
able to connect, the IP should start with a 192. Is this correct?

I hope that someone will be able to help me out.

Thanks alot!
Jing

You don't have IEEE 802.1 authentication, so leave that disabled.

TCP/ip on your computer isn't configured correctly to connect to the router.
The RF connection seems to be fine, but that is a separate function. Enable
DHCP on the router and DNS pass-through. Also enable Obtain an address
automatically in the TCP/ip settings for your computer WLAN adapter.

Hi Ralf,

thanks alot for your help, but could you please tell me how to enable
the DHCP on the router and the DNS pass through? I checked the
properties under the TCP/IP and the addresses are already set to
obtain automatically. What else should I do?
Thanks!

If you originally connected to the router using an ethernet cable, try
disabling the ethernet connection in Network Connections, reboot and see if
the wireless will connect. If not, re-enable the ethernet and use that to
connect to the router. Where the settings are located varies with router
brand and model, so without knowing what router you are using I have no idea
where you should look. Possibly a LAN settings page and possibly a separate
DHCP page in the router configuration. Look for simple on-off options to
enable the functions. You're best off to turn off WEP or WPA until after
you have established a working wireless connection. When you've done the
settings, disable the ethernet connection and test if the wireless will
connect and can access the network/internet. Then enable security in the
router first, computer second.

Hi
To configure the Router you need to be connected to it first. Since your
Wireless does not work you need to find away to connect to the Router with a
wire ( http://www.ezlan.net/faq#onewire ).
Most new Laptops have both wire and wireless capacity. Get a network cable
and start with the wired connection.
May be this can Help.

Hi Ralf,

I'm using a Thomson Speed Touch 570 router modem. Would you have any
idea where to look? I do apologise for being ignorant. I'm not tech
savy and all. I hope that you will be able to help me out.

thanks!

Hi Jack,

Thanks for the info. My laptop is about 3 years old..but I bought a
new wireless card to use on it. I did not have a problem when i was
connected to the WLAN at my cousin's place...but I cant do it at
home....Do you reckon that a new network should be set up?

Thanks

Just looking at the Speedtouch manual.. what a strange beast compared with
what I'm used to.

In answer to your earlier question about addresses, this manual suggests the
router uses LAN addresses in the 10.x.x.x range. The default address of the
SpeedTouch configuration interface should be 10.0.0.138. Your adapter (LAN
or WLAN) has to have an address in that range in order to connect to the
modem/router. DHCP is already turned on so it appears that the wireless
security settings might be the cause of your problem getting connected. The
only way to turn WEP off in the router now would be to connect to the router
using an ethernet cable, using your browser to access the configuration
interface.

First off, if you installed a Belkin WLAN utility to configure the wireless
card make sure that Windows XP Wireless Zero configuration service is not
running at the same time. Administrative Tools->Services->Wireless Zero
Configuration -- stop and set to Disabled.

According to the SpeedTouch manual, the router modem came pre-configured
with a default SSID and 128bit WEP key in 26 digit hexadecimal format,
printed on the bottom of the unit. Unless you changed them those are what
should be entered into your Belkin WLAN adapter configuration. If you
enabled the Registration function (red button on back) of the SpeedTouch,
disable it again. The other default SpeedTouch settings should allow you to
connect so check the Belkin settings.

Double check that the SSID is correct in the Belkin configuration. Check the
Belkin WEP entry to make sure that the key is exactly the same (no o where
it should be 0[zero], i for 1[one] etc.) and that you have selected
"hexadecimal" for input method. Note whether WEP is set to use Shared key
or Open key. Try to connect with it set to Shared. If it doesn't connect
change the setting to Open key and try again.

Apparently there is a "Dr SpeedTouch" utility that came with the router.
You could run that and see what it tells you about your connection.

If it still doesn't connect you might have to start over from scratch. You
can reset the SpeedTouch to its factory defaults by using the reset button
on the back.
