That as maybe but it doesn't explain why the LAN & WLAN are not working on a fresh manual install of XP NOT using the recovery disc. But suddenly work when the USB ethernet adapter is plugged in.

Question
LAN & WLAN fail to work on Toshiba Satellite L20 173
Hi All
I have a strange issue on a Laptop (model above). The recovery CD installs and then on boot laptop blackscreens. I performed a fresh install of WinXP and installed all drivers from Toshiba website. All updates from MS incl SP3.
The issue I have is the LAN fails to function (driver looks fine in Device Manager) It shows a limited or no connectivity unless I enter a static IP address then although it shows connected I can't ping the router.
Also the WLAN fails to show wireless networks intermittently and when it does - refuses to connect to one - enter network code and still shows as not connected. The original WLAN card was a Atheros.
The strangest part of all this is that if I insert into the USB port after installing drivers for it - a USB ethernet adapter this works fine, but also the LAN port and the WLAN connects immediately. Remove the USB Ethernet Adapter and the connection on LAN and WLAN is dropped immediately????
I have installed the OS 3 times now, tried different drivers for the LAN and WLAN from Toshiba and on the web. I have changed the WLAN card to an Intel Pro 2200BG to see if this had any effect - it didn't. There is no security software installed.
This has stumped me! Does anyone have any ideas?

Try getting the latest driver from Atheros instead of Toshiba. They are usually 2 or 3 driver updates ahead of the PC manufacturer. If that does not work you most likely have a faulty internal wireless card. The easiest fix for that is your USB wireless stick, or you could take it to a PC shop to have that part replaced.
I was thinking it a bad hardware port on the labtop. it could be loose on the laptop.
try these drivers

To victorjones1: Thanks for the comments but if you read my original post you will see I stated that I have already changed the internal mini-pci wireless network card from the Atheros to an Intel 2200BG a known working card. This rules out the card being faulty.
To ComputerTechie: & victorjones1: I have also explained the insertion of a USB ethernet adapter instantly makes both LAN port and WLAN card function perfectly which would whilst not ruling out hardware failure make it more unlikely to be the case.
Any other ideas as I am at a loss!
Do you have IPV6 enabled?
To disable IPv6 ICF, follow these steps:
Click Start, and then click Control Panel.
Click Add or Remove Programs.
Click Add/Remove Windows Components. The Windows Components wizard starts.
Click Networking Services (but do not click to clear the check box), and then click Details.
Click to clear the IPv6 Internet Connection Firewall check box, and then click OK.
Click Next.
Follow the instructions on the screen to remove the component from the computer.

Hi Thanks for the checks to follow.
As mentioned in my original comment virgin installation of XP no security software. Laptop is used on a network serving 20 machines all of which are functioning fine. IPV6 not installed. Tried the microsoft tcp/ip reset article - checked DHCP dependencies are also started - they are. Still same problem.
Also ran some pure hardware diagnostics by Ultra-X diags with loop back plugs - hardware tests passed - not that one can rely on these 100% - it seems to me that it smacks of a driver issue. But I have downloaded the LAN driver from Toshiba and some others from the web all specifically for the Toshiba satellite L20 173. At a loss still.
You can try the following driver, but i am not sure if it will work or if this a reputable website:
http://www.bioticaindia.co
This will only work for your WLAN though, because the wired LAN is most likely made by RealTek not Atheros
I have not tried the link above yet - I have downloaded dozens of drivers right the way up to the latest Atheros driver which still does not work. However, with all due respect I still think you are missing the point - I have tried a known working mini-pci wireless card (Intel 2200BG) with known working XP driver software used for test purposes and the card still would not work. But REMEMBER both WLAN and LAN work when a USB to Ethernet Adapter is plugged in and installed with its drivers!!!!! Why this is the case I do not know - this is far more complex than a simple case of which driver or check simple network protocols etc.
I do appreciate any ideas you have but they must be on these lines as client will need an update soon and I will have to say something.
Yes I would generally agree with that too. But the LAN port also does not work. It may be a mainboard issue if there is a single component that handles both of these devices. Some of the drivers for the WLAN worked better than others in that with most no networks were detected at all. On a couple networks were detected but when attempt to connect it failed with no errors just not connected. Normally I would suspect an issue with the driver not supporting or handling the WPA security correctly but I'm not sure on this one.
This is starting to sound like a motherboard issue to me, so i think your best & cheapest fix will be the USB stick or a PC card wireless adapter (only because it sticks out less).
Is this an older model laptop? If so its probably not worth the effort & cost of replacing the motherboard (especially if you are not 100% sure that is the problem).

I have had strange things happen because of these Toshiba recovery disks. Every time so far it is caused by a bad section of the CD. The only fix i have found was to order a new disk from Toshiba for your specific PC. They are about $20.
