Cannot connect XP to internet via P2P network

I'm trying to connect an XP machine (daughter-mobile) wirelessly to my home network behind a Linksys router. The network contains XP, W2k and a Vista machine. I can see daughter-mobile on the network from the Vista and w2k machines, but I can't ping it, and I cannot ping my router from daughter-mobile.
BACKGROUND
I'm not using DHCP.
I have installed NetBEUI on daughter-mobile.
I have enabled NetBIOS over TCP/IP
I have another XP machine (dad-mobile) successfully working on the network.

Ensure you've got it in the same subnet (you mention you're NOT using DHCP), that the DNS servers are entered correctly and then make sure the firewall isn't interfering.

nodreads says:
DNS servers are entered correctly
FW is turned off
Question: how would it be on a different subnet (subnet mask?) How would I check (ipconfig/all?)
Thanks

Glen A.IT Project ManagerCommented:
Yup, ipconfig /all will tell you everything.

In a home network please ensure that the subnet mask is 255.255.255.0 and that first three octets of the IP address are THE SAME - ie:

(for this example we'll assume your router is 192.168.1.A - where 'A' could be any number from 1-254)

your IP addresses for the computers need to be:

192.168.1.x
192.168.1.y
192.168.1.z ...etc...

If they're not on the same local subnet, they won't see each other...

also, try pinging by IP address (numerical) instead of by name...  that will tell you if it's a DNS issue.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Also, are they in the same workgroup?  (I'm assuming you're not running a domain at home?)  It's not essential, but it helps windows figure things out.

If you are not using DHCP on the home-based  LAN side, you will have to set your users up with a static IP address and subnet mask.  Otherwise your user's default IP will probably not be in the same IP space and therefore not be able to communicate.

Also, when you do IPconfig /all to your daughters machine, check and see if you have a line in the text that says something like Toredo tunnel and an alpha numeric IP address. If so, her machine may be using IP version 6 witch is not compatible with IP version 4 routers.  The fix for this is to uninstall the IPversion 6 protocol and install IP version 4 protrocol.

All machines are on the same workgroup and have the same subnet mask
All are on the same subnet (192.168.1.x)
All machines have static IP addresses in the range 1 - 254
I pinged using the numerical IP address
daughter-mobile is not using IPv6

I don't know if this helps identify the problem, but all PCs can see daughter-mobile on "view workgroup computers" but it can't see any of the other PCs (xx network not accessible. You might not have pemissions ... etc)

Check to make sure the Computer Browser and Network Location Awareness Services are started on the XP and better machines....

Also, are you using a wireless router?  Check to see if it has LAN isolation mode enabled

How do I start Computer Browser and Network Location Awareness Services on the XP machine?
Also, I how do I turn on LAN isolation mode on my wireless router?
Note that I have other XP machines successfully connecte to the internet via the router.
Thanks

Start services:

1.  Start > Administrative Tools > Services
         - (for classic start menu) Start > Settings > Control Panel > Administrative tools
2.  Right-click each service and select start if necessary

If you are using a wireless router can any of the wireless computers connect to the rest of the network/Internet?  How about the wired computers?

Both Computer Browser and NLA on daughter-wireless were started.
All other computers, connected via wired and wireless, can connect to the internet.

To be clear: the PC "daughter-mobile" is still unable to connect to the internet.
Any more suggestions, resources etc?

Guys, I think the problem is with the Vista Machine, everyone is able to browse workgroup computers, that means NETBIOS is being used.

NETBIOS master browser will be the Vista Machine since that's the newest version of the Windows OS (2K, XP, Vista)

Is the proxy server settings on your "daughter-mobile" pc configured wrongly?

------

On "daughter-mobile" open command line and ping localhost (127.0.0.1)

Is "daughter-mobile" able to ping ANYONE at all?

nodreads1926Author Commented:
daughter-mobile can ping 127.0.0.1, but times out with anything else (e.g. 192.168.1.1 - the router)
I'm not sure how to check the proxy server settings on daughter-mobile

Glen A.IT Project ManagerCommented:
127.0.0.1 is loopback, anything can ping that...

Sounds like daughter-mobile is NOT connected properly.  Can it ping your router at all (ie: 192.168.0.1) or whatever your default gateway is?

one of the problems with using static IP when setting up a home network is you don't know if you're actually talking to the router or not without pinging it, etc.

If you used DHCP instead, you'd know right away if you're getting an address and as such, communicating properly.

I'm thinking something to do with daughter mobiles network drivers or the tcp/ip settings are not right.  Try setting it to DHCP and plugging into a network cable on the router (rather than going wireless).  If that works, then try wireless/dhcp.  that'll help you troubleshoot where the problem is.

the confusing part is you said the other two can see daughter-mobile, which doesn't make sense... can they MAP to it?  Can they ping it?  Can you access a share on it from the other computers?  If NOT (which is what I suspect) then you know the problem is that networking is NOT setup right on daughter mobile...  

Let me know if you can ping your default gateway/router from daughter mobile.  I suspect you can't...  

does daughter mobile let you see your wireless router when you use the windows (or driver-based) view of available wireless networks?

midustouchCommented:
127.0.0.1 or localhost ping is done to test if your tcpip stack is working at all - that's why the suggestion.
In this scenario, it's also used to establish if the user has TCPIP installed on his "daughter-mobile" PC.

This just occured; I've faced a similar problem with routers that if you don't use the router to assign IP address, the router may not recognize the machine even though it's on the local LAN.

My suggestion:

1. Configure DHCP on your LinkSys Router
2. Get the MAC address of each client connecting to your router
3. Reserve an IP address on the router based on each machine's MAC address
4. Set the machines to automatically obtain IP address and DNS
5. Reboot machines

In addition:

Check that your WEP/WPA settings are correct, if you're using different wireless network clients and you're using password to wep/wpa authentication/calculation method, there seems to be no consistency of the implementation across the vendors - I've a few wireless clients of different brands and encryption is a source of real headaches; I would suggest you disable all encryption first to see if that solves your problems. If it does, then it's a encryption problem.

You have several very good comments already but I thought I would put very simply for you what you need in order to have internet access

1) Your gateway and your machine MUST be on the same subnet
2) if using FQDN's as is usual, you must be ablle to reach a DNS server somehwhere, on your network or the internet
3) Make sure no firewall or other utility is blocking the nework services you need, for instance Port 80 for Web, 53 for DNS, etc
4) if you can ping your gateway, escalate and attempt to ping something outside to test
5) if you cant ping your gateway and the above are in place, you might have a connectivity problem, say maybe you are using mac address filtering on the wireless connection. This will allow you to connect but there will be no data transfer.
