The IDE to SATA interface is difficult to deal with. With Linux you need to build a driver for it which is not in kernel.

MIMO Above and Below Channel Bonding with Superchannel

In the 802.11n spec, channel bonding is done on specific channels above and below the base center channel, like what is described in http://en.wikipedia.org/wiki/IEEE_802.11n#40.C2.A0MHz_in_2.4.C2.A0GHz .

Web Interface in post 3.22 problems

In version 3.22 the web interface has been changed significantly. The tabs are nice, but there are some features that we were using in older versions for customers that are now broken: 1. The dashboard is no longer present. This provided good status information on the system to help troubleshoot wit...

Was Mesh Fixed in 3.22?

In looking through the changelog for 3.21 and 3.22 there is no mention of any changes to fix HWMP, mesh or anything related. Were changes made to fix the routing problems with HWMP? Can we now test with WDS dynamic mesh? Is it worth our effort or should we continue to wait?

Thanks

Re: Ideas on implementing wireless mobile mesh

Uldis, any word on progress with 3.21 release? We are all anxious to get HWMP working for mobile mesh applications.

Re: Ideas on implementing wireless mobile mesh

Thanks Uldis, we are anxious to see the improvements. The issue seems to come up when there are multiple paths across the mesh, a change occurs, then the FDB does not seem to be refreshed properly and paths just don't seem to work. Kind of looks like the same kind of issue we see with STP convergenc...

Ideas on implementing wireless mobile mesh

We have posted several times trying to get to the bottom of using HWMP in a mobile mesh architecture. Like what other systems like Firetide or Strix does using ad hoc mode and OLSR or AODV. The HWMP protocol looks like it should work, but we can get it to scale beyond 4 mesh nodes before it fails. T...

Re: unstable ping with nstream

Have you tried turning off CSMA? Your current config has it on with polling enabled. We find more consistent delay with CSMA off.

Boot loader 2.19 for Crossroads

The link to the MT bootloader 2.19 for crossroads boards is broken on the routerboard.com web site.

We want to load MT 3.20 on boards that currently have 2.12 version of bootloader. Are there issues with this? Can we get the link fixed and get the updated bootloader?

Thanks

Re: Fast link for Sentryscope. 21Megapixel camera.

They look like they support 2fps max at 21MP. But no mention of compression algorithm, streaming engine protocol, etc or nominal bit rate at low mid and high motion. If they are like everyone else, they use mjpeg with some sort of HTTP or FTP streaming (ie TCP) which will be lousy for wireless. You ...

HWMP Mesh - Is it possible

Has anyone successfully implemented HWMP mesh using WDS dynamic-mesh mode with more than 4 nodes? Seems like it suffers from exactly the same issues as just bridging WDS with RSTP. We really want to create layer 2 mesh that scales well using MT, but without using ad-hoc mode (like all other mesh sol...

Re: HWMP, WDS Mesh and Wireless-test

Let me rephrase my posting:

Has anyone successfully implemented HWMP mesh using WDS dynamic mesh with more than 6 nodes?

How?

HWMP, WDS Mesh and Wireless-test

We have been trying to get a mesh configuration running using HWMP that is more scalable than simple WDS bridging. We are using 3.17 on an x86 platform with the standard wireless driver package. We created a mesh interface using the default values. We configured wireless interface with WDS dynamic m...

Re: MME and Dynamic WDS Mesh?

I have not received any feedback on this topic. I am really interested to learn how to implement dynamic mesh routing on MT, but since no one is answering this, I can only assume that it is not possible. This leaves us with layer 2 mesh, which is extremely limited, or static mesh, which, while usefu...

Re: MME and Dynamic WDS Mesh?

I never received any replies or responses to this post. The fundamental problem that I see is that in most mesh implementations they use ad-hoc mode, which creates the layer 2 link point to point with a peer, then OLSR or ADVO decides which link is the best to route over. Each interface is unique an...

MME and Dynamic WDS Mesh?

I have been trying to figure out how to implement scalable wireless mesh using MME. The goal is to have dynamic wireless mesh over larger number of nodes than what WDS alone can support. Ideally self configuring, meaning that every node in the mesh looks pretty much identical and pulls address info,...
