With many laptops, you must set the file system type to LBA in BIOS to get Linux to work.

Even some desktops require it. YMMV

Answ: I have been doing some work on VoIP and using SIP Telephony. I haven' started using SIP over LW as of yet however the problem of not getting a message sound like the SIP telephone requires an upgrade and that you have to open the ports up in your router. Try to connect and get your SIP client working through your router first, not using LW. When it works then try adding the mesh. In the advent that you have done this and are still having problems please recheck your configuration and ensure that

you have followed the direction as per Jon's instructions. I too was having the same 

problem and found that my router changed the DHCP on me and the ports that I opened for a specific address went astray. So I had to reconfigure the Client to a static IP and change the ports on the router accordingly.

Ques: I have seen a few messages stating that incoming calls are failing due to what seems to be a IP address Leasing/DHCP issue.Has anyone else had this problem and/or have any fixes been created and successfully applied that overcome the problem. It seems to me the only way at the moment is run end users with a Fixed IP address and discard the use of DHCP ??



Ques: I've been trying to set up a mesh network with Linux PCs and notebooks. The >mesh gateway works fine and clients can very easily get Internet access from >it. Problem comes when I tried to set up repeater nodes though. > >From the Locustworld.com FAQ it said I only have to boot a PC with the >MeshAP CD to make it a repeater node. But when it actually boots up, it >prints "No uplink connectivity" in tty1. >Running "route -n" and

cat /proc/aodv/route_table shows two routes to

Putting a client machine in range of the repeater will give it a 192.168.x.y IP and a default gateway pointing to the repeater. Opening a web browser on that client shows the LocustWorld login screen with a no uplink warning. I've tried fiddling with both the repeater and the gateway nodes but had no luck. Could someone kindly provide a hint on what went wrong in my situation? Thanks. Answ: I suspect that you haven't changed everything that needs changing to move to the 11.x.x.x network. The meshbox can deal with the DHCP address given to it being a 10.x.x.x address, but it won't necessarily allow its clients to connect to other addresses on that subnet. However, they should be able to access the internet.

Try running with default settings before tweaking things - makes it easier to debug problems. Also, check which version you are running with the MeshAP CD - I seem to remember that the bootable CDs are very old.

[MeshAPuser] Odd UDP/ root server traffic on non-communicating node

Yea. I had the same trouble when I was testing the SIP module out. I beleive it is the Lock To Gateway setting or updating software version that fixed it.


UDP traffic Edit

Odd UDP/ root server traffic on non-communicating node Hi, anyone out here seem this before? A wireless repeater node (1249 firmware) won't ping out or check in anymore, when ssh'd into and netstat -nr, a great many DNS lookups to various root servers show up. BTW this unit has the SIPproxy installed. Any ideas? Thanks...

We found the problem- the repeater box had been changed in Wiana to "always gateway" mode. The DNS lookups were probably the result of users trying to surf unsuccessfully. But the larger question is- why the change in the Wiana settings? We didn't do it, and this is the second time a critical parameter in this particular mesh network has been "magically" changed. Has anyone else seen this kind of thing?
