HI All

I am now starting a project on mesh wireless ad hoc networks.
So, i need some help.

1st: I need to download 802.11x protocol for wireless mesh ad hoc network so, different devices (pc, pda labtop etc) can communicate with each other with out any Access point but with blue tooth or anntena etc.

Now any one knows about these protocols which should i have to use.

And suggestions on this project.

People who thinks they are expert on this , we can form a group through this forum. I also have to write min 2-3 papers so, i will add ur names in it.

Thanks

Summary: the thread describes a small experimental mesh on Windows XP using Microsoft’s Mesh Connectivity Layer and AODV where the virtual mesh interface comes up for a few seconds, then drops, and Internet Connection Sharing collides with the ISP’s private addressing. The items below add focused, practical diagnostics and short‑term fixes that complement and without repeating links already posted.

Common root causes and focused checks

  • Driver/utility interaction: many Windows-era WLAN drivers and vendor wireless utilities will rebind or reset the radio, which disables MCL-created virtual adapters. Updating or temporarily removing the vendor wireless manager often prevents mid‑session drops.
  • Logs and state to capture when the adapter is up: Event Viewer/System logs, MCL service logs, and a small set of Windows state dumps. While the virtual adapter is enabled, capture these outputs to files for later analysis:
ipconfig /all > C:\temp\mesh_ipconfig.txt
arp -a   > C:\temp\mesh_arp.txt
route print > C:\temp\mesh_route.txt
ping -n 10 10.77.77.2 > C:\temp\mesh_ping.txt

Also run a short packet capture (Wireshark) across the WLAN interface to confirm whether ARP and ICMP frames are being transmitted during the few seconds the adapter is active.

ICS and addressing practicalities

  • Avoid address overlap with the ISP by choosing a non‑conflicting private subnet (for example 10.77.77.0/24 or 172.31.100.0/24) for the mesh and assign the mesh gateway a static IP on that range. Windows ICS is known to impose its own addressing behavior (historically using 192.168.0.1); if ICS cannot be made to cooperate, use a small dedicated NAT device or a Linux box for the gateway/NAT role.

Suggested next steps (concise)

  1. Update/remove vendor WLAN utility and retry. 2) Reproduce the drop while collecting Event Viewer + the text dumps above + a short packet capture. 3) Try a different WLAN adapter or a Linux live system running a mesh routing daemon to determine whether the problem is driver/Windows-specific. These steps align with @DimaYasny’s Linux suggestion and clarify how @Kashif’s symptoms map to driver/service rebinds rather than a high‑level routing bug.

This is Last post on this website forum for this problem. If Any one can help me? so i can continue.....
So far I have installed MCL for mesh connectivity but i am facing a problem of Virtuall connection disabled after 4-6 sec

both PCs WinXP SP2and WLAN cards same vandor (TP Link)

Member Avatar for jbennet

different devices (pc, pda labtop etc) can communicate with each other with out any Access point but with blue tooth or anntena

This functionality is built into XP SP2 and PocketPC version 2003SE and above

Its called an ad-hoc network

Thanks for reply

Yes I have created MESH1 SSID and conected them But Virtaul Wireless adapter Created by
Mesh Connectivity Layer(MCL) disabled after 4-6 sec when enabled.

After this WLAN card enabled and connection MESH1 found and connected automatically
but no ping between them.

But When i ping both PC with each other within 4-6 sec while Virtual Wireless Connection is
enabled both PCs ping each other.

I want to know where Problem Lies, wat should i do?

Thanks again

looks like mesh wireless isn't well implemented in general yet - some proprietary solutions, no real standards. just choose a protocol and work along it - read the rfc. in any case windows (especially home edition) wouldn't help you out much, look for linux distros with the protocols built in

Thanks ur here

After Stuck with MCL i tried AODV protocol

"UoBWinAODV - Windows AODV Protocol Handler (ver 0.15)"

Link:

Member Avatar for Kashif

Last link u send i tried that
i downloaded MCL from there

Member Avatar for Kashif

And i go to AODV protocol page i sent u from ur 2nd last link

Member Avatar for DimaYasny

here's some howtos I've dug up:

Member Avatar for Kashif

I am using WinXP Pro SP2
I stuck in MCL as described above
and now in AODV there is install.txt in 7th step error in config file reading

Member Avatar for DimaYasny

I'd try to email the guys who wrote the howto's if I were you, as I said, I'm no expert

Member Avatar for Kashif

Thanks Useful links

Wat exactly i want is to connect three PC's with each other without AP using Wireless LAN card and one of them route there request to the AP for LAN or Internet

Member Avatar for Kashif

Thanks two brains having some idea can do some think useful as ur helping me out with useful ideas , links and emailing some.

I am very greatful to u

Member Avatar for DimaYasny

no problem. if I had some wireless computers here I'd try to look for a solution, but I'm in the middle of a relocation process, and all I have is my laptop

Member Avatar for Kashif

mean while i think i should try Adaptive Wireless Path Protocol (AWPP) also its good link thanks

Member Avatar for DimaYasny

have fun! :)

Member Avatar for Kashif

But there no link for download software i tried google but all in cisco

Member Avatar for DimaYasny

contact cisco then.

Member Avatar for Kashif

Please if u know some one ask him wat i want to do(as exactly described above).

And Try to find from where i should start (Which Protocol, Software and Hardware requirments etc.)

Member Avatar for Kashif

No AP should involve when three PC's Communicating with each other or Hardware device (like cisco routers) one of PC in Mesh Can only route the request of other who can access AP for Internet or otherside LAN

Member Avatar for Kashif

I am able to connect PCs Through mesh network
Now
I am trying to connect them to internet I know
Possible sol. that internet sharing on last node but my internet provider is using 192.X.X.X series already i cannot share the net so, here i need help.. Now wat should i do now...Very simplest way.

Thanx

Member Avatar for DimaYasny

change your own network addressing
if you use and so does the ISP change yours to

Member Avatar for Kashif

Thanx DimaYasny

i try and then tell u.

2nd u told me that ur cisco friend for mesh help did u contected him?

Member Avatar for DimaYasny

he is pretty hard to reach, and my current company doesn't go into high end networking like that

Member Avatar for Kashif

thanx when u got some thing email me or reply

Member Avatar for Kashif

still error

when i used on LAN card (ICS error)

when i used on LAN card (Invalid bits error)

Member Avatar for DimaYasny

you can't use a .0 as an IP - it's a network address

Member Avatar for Kashif

but 1.1 is not working also

Member Avatar for DimaYasny

what is your network anyway?

Member Avatar for Kashif

MY IP IS ON WIFI NIC AND IP of AP is and DHCP server IP is
