Toshiba keeps disconnecting from LAN

[Orson]

I've just bought a Toshiba Dynabook, and I'm having major problems with my
LAN. I'm not too technical, and I'm at a real loss..

My desktop is fine, and the new laptop can see the network, but is unable to
get an IP address (it says) even if I click on 'repair'. It has a built in
wireless LAN - Intel PRO/Wireless 2200BG Network.. My router is made by
Laneed. The computer is brand new XP with SP2 pre-installed.

The only solution for me is to unplug my router, and then plug it back in. I
click on repair, and can connect to the Internet. I find that most strange!

However, after 5 minutes, it suddenly loses the connection, and I'm back to
the beginning. Holding my mouse over the taskbar tells me that it can see
the network, and that the signal is very strong. I have no idea what to do.
The kicker is that I'm in Japan (my OS is Japanese), and I can't read the
manuals very well!

When it is connected (for the precious few minutes), the connection status
says that the address type is assigned by DHCP, and the IP is one digit
different from the one on my desktop.

I rang Toshiba support, but they couldn't help... Any suggestions would be
gratefully received....

Check the Authentication options in your wireless network adapter's settings
and make sure that you don't have 802.1x authentication enabled. You'll
find this by right-clicking your wireless adapter in the Network Connections
box, selecting Properties, then the Authentication tab.

Hello - thanks for the replies.

My problem laptop doesn't have an authentication tab. Instead, it has
'Wireless Network' as the middle option, between 'General' and 'Advanced'.
(I think I'm translating correctly...) There's no mention of 802.1x

My NEC desktop with Windows XP SP2 does have the Authentication tab with
802.1x checked. I don't understand why desktop and laptop are showing
different information...

In addition, at the advice of Hans-Georg Michna, I went to the website, and
went through the diagnostics. It told me to post the following info:

wireless=1 sporadic=1 ip=1 ping=2 ieoe=1

I rang both Toshiba and my router's support numbers, but they couldn't
help...

Your help here really is appreciated.

Perhaps the wireless NIC in the laptop has its own configuration utility, so
you may want to look there to find and disable 802.1x authentication. Not
sure where it would be, but it's worth a look.

I found the UEEE 802.1x box. It's not checked. Actually, it's greyed out
because (it says), I have an ad hoc network...

Still only able to reconnect by unplugging the router. But I still then get
kicked off after 5 mins.

Hi Orson,

Thank you for posting here.

I would like to recommend that you uninstall the network card, then reboot
and follow the
steps in the found new hardware wizard to reinstall network card.

If the problem persists, please try another PCMCIA wireless card.

What is the result?

Bob Qin

Orson,

did you follow the recommendations on
http://www.michna.com/kb/wxnet.htm ?

Hans-Georg

 

[Orson]

Yes - I followed as much of the advice as possible, including updating the
driver from Intel.

It still gets stuck - clicking 'repair' doesn't get past the part where it
tries to get an IP address...

Orson,

how about the short chapter on "Energy saving"?

I guess it is now important to know which parts of the advice
you could not follow.

This is happening to me to, with the Toshiba Satellite, last gadget on the
market. I am no newbie and tried all the tricks, and I checked on Michna's
site to see if I would find something I hadn't already tried. I didn't. I
unsinstalled and reinstalled just about everything...

And I did try one more thing, not mentioned here: I connected to the router
(which is working beautifully for all other computers on my network) directly
via Ethernet cable. Same thing. It stays connected for a while, and then the
connection just drops. Nothing is wrong with the setup, with the
connectivity, the protocol, the (absence) of the XP firewall, etc etc. It
just drops. (and yes, I did try with a different cable)

One more detail: the ethernet-connected XP Pro laptop IS on the network, I
can ping the other computers, and I can see them. I can exchange files and
the whole bit. It REFUSES to see the gateway. If I put it back on the
wireless, it does not see the DHCP (as Orson mentioned too).

I am not sure yet whether it is a XP bug of sort (all my other computers and
laptops are running 2K), or a Toshiba's. Saying that the Toshiba support was
unhelpful is an understatement. They almost made me decide to return it right
away for a refund.
However, I am determined to get to the bottom of this.
Anybody out there with more creative suggestion, I'd be most grateful.
Meanwhile, I'll keep trying. If I find out anything more, I'll post it for
Orson as well.

Take care,

AID

I'd be very interested to learn what it was, if you can solve
it.

I think of energy saving enabled on the network adapter, of
802.1X authentication enabled, of obsolete drivers or router
firmware, and of spyware and the attendant Winsock corruption,
but these are all mentioned on
http://www.michna.com/kb/wxnet.htm.

Hello there. The update at the moment is that nothing has changed. I have
tried 802.1X authentication enabled, and disabled. I also updated the driver
from Intel's website, tried changing energy saving settings and so on. All
to no avail.

I put a different wireless LAN card in the computer, and that worked
perfectly!

Toshiba 'support' tell me that they have an office in Tokyo (where I am),
where I can get the machine checked out. I'll go this weekend, and report
back.

Orson

 

[Hans-Georg Michna]

Orson,

hmm, interesting! That seems to indicate to me that the
operating system probably can't be blamed. It may be a Toshiba
problem after all.

Could be some incompatibility between the WLAN adapter and the
base station or router. Have you ever tried that laptop in a
different WLAN environment? Or perhaps the adapter has a problem
with the "ad-hoc" network situation.

But I'm only throwing wild guesses around.

Hans-Georg

 

[Orson]

It's fixed! I went to the Toshiba repair centre today, and spent about an
hour there. They tried everything, and eventually did the one thing I hadn't
done: updated the router firmware. I hadn't done it because I have no idea
how to do it, and the company's (Japanese) site is pretty incomprehensible.

The Toshiba chap did it for me, and the computer's been fine ever since.

I'd like to thank everyone on this thread for taking the time to help me.
It's greatly appreciated.

Orson,

thanks for reporting this success!

Since updating the router firmware is explicitly called for in
the very first reply to your very first question on Oct. 12, in
http://www.michna.com/kb/wxnet.htm, you wouldn't actually have
needed anybody's assistance.
