can't see network

Dell Dimension 2200 desktop
September 23, 2009 at 18:30:38
Specs: xppro, 2.4g/3g
i have a friend who's on a network of several computers at her work. her laptop can get on the internet, but can's see the network (has seen network for over a year, til now) no new software or hardware added. she has a 5 port hub and access point in her room, both work fine as tested by another laptop. she also can't see network when connected directly to ethernet via a cable. oh, she can see some other wireless laptops on the network, but these are connected via cable and not close enough to use any wireless access point.

nothing shows as a problem in device manager, but i did update her wireless nic drivers. she has a intel pro/wireless nic 3945 abg. intel pro wi-fi wireless says connected to wavelan network - excellent strength and quality of signal speed = 11.0 mbps. she can see her wireless laptop from other computers in the building.

her business uses a work group, not a domain. work group has correct name. uses dhcp. linksys is the 5 port hub and the access point is orinoco. hardware radio switch is enabled. no one at her work can figure it out. any suggestions would be appreciated. thanks,

Open a command prompt, run ipconfig /all & post the results.

That is not an ipconfig /all

Did you note if netbios over tcp/ip is enabled from the ipconfig /all?

This is what a ipconfig /all should look like

If she is really doing an ipconfig /all and only gets the results of an ipconfig plus dns [ipconfig only does not list dns info] then I have to think there is something wrong with her tcp/ip stack.

This is what ipconfig should look like
C:\Users\JUser>ipconfig

Windows IP Configuration
Wireless LAN adapter Wireless Network Connection:

Connection-specific DNS Suffix . :
IPv4 Address. . . . . . . . . . . : 192.168.0.105

Default Gateway . . . . . . . . . : 192.168.0.1

see why I think there has to be something wrong with her tcp/ip stack?

We had an internet station that was infected with malware/virus that changed the tcp/ip stack so you could NOT get ms updates but you could go to microsoft.com. It blocked av and spyware updates but you could go to the sites.

Has she spyware/malware/virus scanned?

Might just try uninstalling the msclient, then the protocol stacks then the nic and then recreate after a reboot.

What do you mean by "cant see the network"?

Lookig at your IPconfig you are seeing the network just fine because you did not get an APIPA address. To confirm this type PING 192.168.0.1 and you will see that you are talking to the WAP atleast.

If the problem is that you are not seeing the other computers then tell us what an IP address is on one of the other computers?

Also what the result of pinging that address is?

I have a feeling that your Access Point has lost its configuration. Your network is probably on the 192.168.1.x subnet and your WAP is now on the 192.168.0.x subnet. If that is the case then you need to configure your WAP so that it is on the same subnet as your "Network".

Look at the device manager for red or yellow marks next to adapters.

Is Norton or some other garbage running on the laptop. Check the firewall settings too.

Still need an answer to this question:

What do you mean by "cant see the network"?

If you can ping the other devices such as the server and router then you are seeing the network. And this means there is nothing wrong with your drivers. So please answer the question so that we know what is wrong. What is it exactly that you can not see. Can you not open file shares on the server, can you not see the printers, or is it that you can not get on the internet?

Make sure you are tweaking the correct interface since you have both wired and wireless.

get an ipconfig /all from another workstation. Is it peer to peer for node type also?

Unknown is a problem. We will get to that momentarily

That protocol stack is a mess! MS doesn't know which language to talk to others in!

Is she connecting to a netware server????

If not uninstall the following:

client service for netware
service advertising protocol
nw linknet bios
nwlink ipx/spxnet bios compatible transport protocol

None of these are required either unless they are running a ipv6 network.

microsoft tcp/ip version 6
auto internet protocol [part of ipv6 - not needed]

netbeui protocol [not required at all]

You will need to edit the registry to correct the node type to hybrid.

Here is the link on how to do it.

also followed link to regedit node, but came to a dead end.

The other office pcs have the same protocol stacks loaded?

That office is a mess. They are in a workgroup with never a mention of a Novell Netware Server.

Appears to me stuff in the office has just been loaded unprofessionally concerning networking components. This isn't just a problem with this device but the entire office.

The only things needed across the board for a workgroup are as follows;

Client for Microsoft Networks
File and Print sharing for Microsoft Networks
Internet Protocol (TCP/IP)

When you mix different clients/protocols you get into binding and protocol order issues. If one machine is talking netbeui as primary protocol, another IPv6, yet another IPv4, another nwlink, none of them can communicated even if they all have the same stuff loaded.

I believe the office is ready for a network makeover.
