Hello, I have a fairly 'basic' peer to peer setup with a HP Pavillion Laptop
using an Intel Pro Wireless 2200BG and a DELL Desktop which I have just
installed a D-Link DWL-G510. I have spent the last 3 days trying to get this
to work and have had no success. I was hoping to be able to use the old 'plug
and play' approach but not to be so. Hmm, after 3 days of headbanging I
thought it was time to seek help.

The situation is that the computers can see each other and connect on the
wireless network that I have setup. I have tried to keep it simple and both
have WEP disabled so no encryption present. I have also setup a windows
workgroup and setup up each individual computer on it. Also, both computers
are running XP Home addition with SP2.
The symptons are:
-I have had to manually set the I.P. address of both computers so they are
within the same workgroup, i.e. 169.254.39.0 for the laptop and 169.254.39.1
for the desktop.
- On the laptop I can see both computers in the workgroup using explorer but
cannot access any shared directories/printers on it.
- On the desktop I can see the workgroup but when I click to see what
computers are on it, it gives me an 'workgroup is not accessible' message
after about a minute.
- From the desktop I can ping the laptop computer but when I ping it's own
address there is no reply and it times out.
- From the laptop I can ping itself but when I ping the desktop it times out.
- The packets received is only about 3-4% of the packets received on both
computers. i.e.889 sent , 18 received.
- I suspect there is an issue with the desktop setup since I can't ping it
from anywhere and can't see any computers here. So I have displayed the
ipconfig /all for the desktop below - I have 1 dial up internet connect, 1
disabled wired LAN connector(currently disabled) and 1 wireless network
adaptor.

Windows IP Configuration

Any help or advice would be greatly received.

Have you set both wireless NIC's to ad-hoc mode? This is necessary for a PC
to PC wireless connection when there is no WAP or WRouter involved.

The 169. address range is technically reserved for AIPA (Automatic Private
IP Addressing) - automatic assignment by Windows when no DHCP server is
found. It's unusual to assign static addresses this way. I would suggest
using 192.168.0.2 and 192.168.0.3 (for example) with a subnet of
255.255.255.0. The one unusual thing I see in your ipconfig output is the
use of the 255.255.0.0 subnet on the desktop rather than 255.255.255.0
subnet. If different on the laptop, that might be your main problem.

For file sharing with XP HOME, also make sure the guest account is enabled
on both machines. Run the command
net user guest /active:yes on each to be sure. Also, configure any
firewall properly, etc.

Hi there, thanks very much for your post.
I can confirm that both NIC adaptors are set to Peer-to-Peer only. I have
changed the IP addresses of both of these to the range that you suggested and
still no luck. I also ran the cmd you suggested for guest and unfortunately
this made no difference also. I have disabled my firewall settings for my
wireless connection so this should not be a problem.

For ref, here is my new ipconfig for my desktop, followed by the laptop:
Windows IP Configuration

For the laptop:

Ethernet NIC
Physical Address. . . . . . . . . : 00-C0-9F-75-3C-19

I have also contacted D-LINK tech support, although they went through some
of the very basic questions and are escalating to level 2 support.

I am still suspicious of my network card in the desktop as I can not ping
it. Is there any reason why this would be the case? Even with software config
being wrong I still would have thought I could ping the IP address of the
desktop from the desktop without a problem.

Any other suggestions would be greatly appreciated.

Thanks in advance.

I agree that the ping problem on the desktop indicates a problem. Can you
ping 127.0.0.1? (This is the loopback address.) If this fails also, it
may indicate a problem with the TCP stack. If it works, it will tend to
point to an issue with the NI (sometime this is the result of a firewall
issue, but you said that's disabled.) Let me know and will try to advise
further. I don't see any problem with the ipconfig outputs you posted.

Whoo hoo! Bingo!

The problem was an older firewall that I had on my desktop computer. I had
completely forgotten about this until you mentioned it again. I had disabled
the windows firewall which was linked into the NIC Config but overlooked the
norton one I had setup a few years ago. I kick myself for not realising this
earlier. Thank heavens I was able to tap into this newsgroup and get your
help.

I can now ping the IP address and can see the shared folders on both
computers.

Thanks mate. You have saved me a lot of trouble.
Appreciate your help heaps.
