Network Woes

Networking problem:

Machine 1: Main desktop using direct Ethernet Connection from Linksys
WRT54G, XP Home

Machine 2: Second Desktop using Linksys Wireless Connection, XP
Professional

Machine 3: Laptop using Linksys Wireless Connection, XP Professional

Machines 2 and 3 see each other, file sharing works fine.
Machines 2 and 3 can see Machine 1, but can't access files
Machine 1 can see neither 2 or 3.

Whenever 1 tries to view all workgroup computers, or #2 or #3 try to
view contents of 1, "XXX not accessible" message results.

Net View IP works on all machines in all directions, but net view
using computer names replicates the same results as above.

All the machines have no trouble accessing the Internet. I've serached
the Micorosft Knowledge base and the groups and have found all sorts
of NetBIOS over TCP/IP stuff, and making sure that no firewalls exist,
but nothing works. Is there something simple that I'm missing?

I'll give my usual list of possible fixes, and I think that #4 is most
likely to help:

1. Permanently disable XP's built-in Internet Connection Firewall on
local area network connections -- it's for use only on a direct modem
connection to the Internet. Disable and un-install all other
firewalls while troubleshooting. Details here:

Windows XP Internet Connection Firewall
http://www.practicallynetworked.com/sharing/xp/ic_firewall.htm

2. Use only one protocol for File and Printer Sharing. If the network
needs more than one protocol, unbind File and Printer Sharing from all
but one of them. Details here:

Windows XP Network Protocols
http://www.practicallynetworked.com/sharing/xp/network_protocols.htm

3. Make sure that NetBIOS over TCP/IP is enabled on all computers.
Details here:

Enable NetBIOS Over TCP/IP (NetBT)
http://www.practicallynetworked.com/sharing/troubleshoot/netbt.htm

4. Run "ipconfig /all" on XP and look at the "Node Type" at the
beginning of the output. If it says "Peer-to-Peer" (which should
actually be "Point-to-Point") that's the problem. It means that the
computer only uses a WINS server, which isn't available on a
peer-to-peer network for NetBIOS name resolution.

If that's the case, run the registry editor, open this key:

HLM\System\CurrentControlSet\Services\Netbt\Parameters

and delete these values if they're present:

NodeType
DhcpNodeType

Reboot, then try network access again.

If that doesn't fix it, open that registry key again, create a DWORD
value called "NodeType", and set it to 1 for "Broadcast" or 4 for
"Mixed".

I have checked everything in your suggestions and mine still has the same issue. The only thing that is not as you state is my network node is set to hybrid with the DhcpNodeType set to 8. Not sure if that is causing it has your notes says peer to peer will not work. From what I read hybrid should work for both peer to peer and point to point. Any further suggestions
