I have 2 Laptops (both wifi) one of which I use at home and is connected to
the internet. I was trying to set up a adhoc wifi net between the 2 and did
exactly what is mentioned at
http://www.microsoft.com/windowsxp/u...p/adhoc.mspx#1

Both the laptops are connecting to the ad-hoc network when I see in the
"Wireless Network Connection" window (clicked from tray icon). However in
both case only the send packets is showing some figure while the recieve
packets is remaining zero under connection status. When I try to ping each
other - from host it says timed out and from client it say host not reachable.

I have disabled all firewalls. The laptops are - IBM Thinkpad R 50 and
Lenovo Thinkpad R60

Any idea what could be the problem, what to check and possible solutions

Hi
How are they connecting to the Internet?
If you have a Wireless Cable/DSL Router you just need to enable the sharing,
no need for ad-Hoc.
If you do need ad-Hoc, try first with the security Off. If the laptop are
set to high security it might be that ad-Hoc does not support it.

There's a limitation with that article. It shows how to setup the WiFi network,
but doesn't tell you about setting up IP over WiFi.

With a NAT router (with or without WiFi), you take for granted the DHCP server,
which provides the IP settings automatically. With Ad-hoc WiFi, you have to
setup IP yourself.

: Most WiFi equipment, in ad-hoc mode, will only operate in 802.11b
: mode, and get up to 11M of bandwidth total.

Assuming you're correct, don't you mean 802.11b/g WiFi equipment?
802.11a equipment should still operate at something like under 54/2 Mbps
in ad hoc mode?

And this 802.11b/g equipment, wouldn't it have to operate below half the
11Mbps in ad hoc mode?

Good questions, all.

I haven't worked with 802.11a enough, and I've never seen a business case where
802.11a was used in ad-hoc mode. With WPA protection requiring infrastructure
mode, not a lot of businesses (or tech savvy individuals) are willing to risk
ad-hoc and WEP.

I would guess that the firmware in the WiFi devices would determine the
bandwidth possibilities.

As far as operating throughput, 11Mbps (or 54Mbps) is a maximum. I never plan
more than 1/3 maximum. You do not control the spectrum, unless you are in the
middle of nowhere.

Hi,

Thanks for pointing it out. Could you please provide a link to do this IP
setting. I could not find it on your blog which was a great read though.

Cheers
Parag
