Topic : Problem with my WRT54GL

After successfully installing firmware V0.4.1 on my Linksys WRT54GLI was playing around with different configuration and changed from “mesh node” to “mesh access point.”

 Now I am unable to get back into setup using http://172.27.0.1:8080

What do I do now?

Topic : Webinar was great!

Greetings all!

I saw the article on QRZ.com and registered.  This was very informative and shows that the developers have all done a great deal of work to make this so much more than I've seen in the past.

I hope to have at least 3 WRTs up and going soon. 1 at a high repeater site and 1 each in mobile and portable service.  If I understood the rules correctly there was to be no foriegn traffic on these.  Would that include any DX stations over Echolink?  I want to be able to use this to route Echolink to a high repeater site from a site we use now about 6 miles away that has good line of site.  We are now doing this on 440 but we want to put the 440 repeater on the tower as well and move data this way.  Is this within the rules?

BTW to the person that asked for the GPS logging there is a way to do it now.  Fire up Netstumbler and sort what you find by SSID.  It works great with most GPS RX.  I do look forward to seeing it in the firmware though.

Topic : Why not 3 Ghz?

3.3Ghz - 3.5Ghz is a ham allocation, so why compete with the 2.4ghz?

Nothing like spectrum with a low noise floor!

Topic : 2.3GHz band plan

I had this all typed out...but it lost it, to summarize though, I'm no expert in devices outside of the standard 802.11 2.4GHz readily available and cheap devices out there...I would think cost being the only real factor, 900MHz equipment would be better I would assume for range, but I dunno all the laws around this, but to be up front I'm still learning the radio side of things rapidly, and already know the data/ip networking/etc side, and how to build embedded squashfs images, develop, etc. It's funny how I stumbled across this project a couple days ago by picking up a faint (-94dBm) ssid labeled hsmm-mesh, google revealed the rest - a project I've been wanting to start up for some time..drive down the price of global communication until it's free.

Topic : WRT54G help

Starter projects could be as simple as having a IP cam on one node, and viewing it across the mesh to a PC on another node. Then if you had 2 PC's, setup file sharing and transfer files back and forth. My neighbor "likes to practice with file transfers from my 500GB 'music' share to his PC" ;-) ;-) If your IT guy brings in the book, READ IT. It may sometime seem a bit long in the tooth, but whatever you can gleam from it would be well worth it IMHO. (but then, Im a PC/network geek by trade anyways :-) ) The point here is, ANYTHING that can be done over a "regular" network can be done over Mesh. 73 KTF

Topic : WRT54G help

K5KTF, I am new to the networking side of the world but great with the RF world. I really just want a small setup but everything I read engulfs me. To me, all lot of the documentation is for larger networks. Would you (or anyone) walk me though the setup for a really side mesh?

Here what I have:

two (2) WRT54G w/ HSMM-Mesh firmware

two (2) WRT54G w/ Linksys

old laptop w/o wireless

HP Mini wireless

What would be a starter project to begin? My man cave is on the 3rd floor with the old laptop and mini is on 1st. Just want to know the setting and a piece of software to run. I what to see it work, then build off of it.

Meanwhile, I have asked my ITC so many questions at work he is bring in his old book from school to shut me up.

Thanks

Josh

Topic : WRT54G help

Hi Josh, You can do whatever you do on a standard TCP/IP network. Transfer files between PC's, hook up IP telephones, IP cameras, etc etc etc. But please do NOT use it for 'regular' internet access. That should be done outside of ham radio usage with normal routers, etc. Using the internet to update the firmware, maybe other ham-related activities, OK. But to just surf willy nilly, thats starting to cross the threshold of Part97. The real thing we need to happen is to get many more people to get working nodes, so we can all connect to each other and to the hospitals/EOC's/etc so we can have an emergency network up and going. As far as that goes, we are still in infancy. Now that the firmware works really well and fairly automagically, I hope more and more will come online. My neighbor and I transfer files, I log in to his nodes when he runs into an issue and help configure, test range, etc. I have ports open that he could send email or RMS Winlink email through, he can hit the web server, view my camera, etc. Just stuff to practice while we wait for others to get nodes up and going, so we can all get connected. If you have/find an application to use over the mesh, please post it to the forums (specific area for them) for all to see and get ideas. 73 Jim K5KTF

Topic : First HSMM Project

Hello, I am very new to this and should stick with small projects but here is what I want to build. A mobile site (car or boat) transmitting video. Then, that signal being received by the network and available to the users.

It sounds so hard right now but I think the HSMM could do it. I read about all of these crazy networks. What do you think?

Thanks you for all of your help. I am stumbling through this. I purchased two WRT54G (Version 1.1) and upload the software. It worked.

Now, what do I do with them???

Back to the manuals….

Feel free to help with whatever is next.

Sorry for the delay. I was TDY to Portsmouth, Va. (Coast Guard stuff) I just got back and read ae5ae's post. He is soooo correct! I was reading the version number from the 192.168.1.1 page. Not the sicker in the bottom of the router. I must have missed that part somewhere but it makes me fell better. I was going crazy with the project.

The Goodwill down the street has about 10 of them sitting on the shelve for 8.00 each, so I will pick up two new ones in the morning.


Thanks again,

Topic : WRT54G help

Small note -- those version numbers that Josh mentions are LinkSys FIRMWARE version numbers and not the HARDWARE version numbers that we generally go by. The 54G's that Josh obtained may not have sufficient FLASH & RAM to load the regular OpenWRT let alone the HSMM-MESH configuration.

The hardware version for a particular 54G is located on a sticker on the bottom of the unit in the little box that says WRT54G Version.... Only Version 1.0 did NOT have a version listed.

Again, if the hardware version for a 54G or 54GS is 5 or greater then the HSMM-MESH firmware can not be loaded.

OK, on the WRT54G v.1xx, what state is it in now? If it is still in the standard Linksys state, I would try and re-download the firmware file for your specific one again, just in case something on the download got weird. I have seen this kind of thing happen. Once you have got it again, then log into the router, go to the firmware update page, select the file from your drive where you saved it, and click update/upload. From there, what happens? Walk me through what you see, and maybe we can figure it out. thx & 73 KTF

Well, I have tried so many frimware options that I made myself a little confused.

If you have the time I will write what I have and maybe you can help point me in the right direction.

Two Linksys:

WRT54G v.1.00.9

WRT54GS v.7.2.06

I have tried OpenWRT and DD-WRT. Both did not work. It is must likely my fault, I do not have any IT background. If it was a T/R or radar I would be all over it. (Coast Guard ET1)

Which should I try again and any pointers?

Topic : WRT54G help

Good morning,

I ran across the HSMM artices and it got my attention. Now, a few trift stores later I have my WRT56G's and am trying to upgrade the firmware via this site. I have a WRT56G V1.00.9. It should upgrade easily, but it is not. It fails every time. I double check the right software (hsmm-mesh-0.4.0-wrt54g.bin)

If you have tips or know what I am doing wrong, please speak up.

Thanks in advance

Josh

This was first reported using a proven file. Its MD5 value was ce9f3cfcf9a429ac34b9c8131c8dbbe1

The file for 0.4.0 firmware now posted is unchanged from first release (MD5 above) and works with browsers other than Chrome.

Topic : 2.3GHz band plan

From time to time I ponder using 900MHz or 3.4GHz wifi devices for hsmm, and one of the things that gets in the way is the ARRL band plan. On the 900MHz band, some of the available wifi devices use channels that are on fm inputs, ATV, and fm outputs, and basically aren't compatible with the band plan. It finally dawned on my to see how the 2.4GHz wifi devices adhere to the 2.4GHz band plan.

Kip's spreadsheet shows this clearly.

Should I have any misgivings about not adhering to the 2.4GHz band plan? And if so, why not?

Topic : vi editor

While an hsmm-mesh node automatically configures itself to connect to other hsmm-mesh nodes, sometimes you might need to make changes to its configuration using the command line interface. One of the packages that is installed on the node is busybox, which includes a number of tools. One of these tools is an editor called vi.

The vi editor has been around since the early days of UNIX. A short history of the vi editor can be found here: http://www.softpanorama.org/Editors/Vimorama/history.shtml.

Today, there are lots of editors being used on linux, wysiwyg editors, context sensitive editors, extensible editors. Unfortunately, none of those editors are available on the hsmm-mesh nodes (to my knowledge). The problem with fancy editors is that the more features they use, the bigger they are, and the more burdened the CPU becomes.

When I was at UT/Austin, I started off with the emacs editor. It was wonderful. I could write macros in lisp and spend more time playing with emacs than with the program I was supposed to be writing. Alas, as the end of the semester approached, more and more people were online, and the editor became slower and slower. In the end I was forced to use vi just to get my work done.

The vi editor isn't that difficult to use. Unforunately, hsmm-mesh nodes lack the usual online documentation (man pages), so there's no help available for vi. However, there are tutorials available online. Here's one: http://www.eng.hawaii.edu/Tutor/vi.html. As you start to use the vi editor on your mesh node, just remember that the vi editor that comes with busybox has a reduced feature set. Even a small editor like vi has too many features for use on a mesh node.
