If you can upgrade the other nodes in the network that may be better. All versions before 1.1.0 had a routing security flaw and 1.1.x had some serious stability issues.

Assuming you need to and can't do an upgrade the details were discussed here for downgrading http://www.broadband-hamnet.org/hsmm-mesh-forums/view-postlist/forum-1242/topic-1242-downgrading-from-3-beta-code-to-101.html

Is it possible to boot back from ver 3.0.0 to an older version? Speaking about WRT54...

I have three nodes set up on my farm that monitor and control everything from the greenhouse to the solar systems and equipment in the barn. Node 2 connects to an Arduino Uno programmed as a web server to monitor and control some greenhouse equipment where as node 3 uses a serial to ethernet link to an Allen Bradley SLC 5/03 PLC which oversees and logs quite a bit of day to day activity in both the greenhouse, barn and alternative power sources.

The attached photos show how I set up the port forwarding since it sounds very similar to your setup.

It's not likely bricked, it's just that going into mesh_ap mode disables the dhcp server so you need to manually set your ip and log in to recover. 

Thanks gentlemen.

Thats put my mind at rest, however still got a bricked modem when I went to AP mode, luckily I have two!

I just went through every document on the website the other day. You can find out which antenna is Right or Left by navigating to FAQ --> Hardware FAQs --> 7. Antenna's Right and Left.

However...The WRT54G3G only has one antenna. If you leave it on diversity the device will select the antenna that has the strongest strength...and since there is only one, it will select the only antenna.* Alternatively, you can try to figure out which antenna selection it is.

*Source: Chapter 10. Pages 7-8. http://wndw.net/pdf/wndw3-en/ch10-deployment-planning.pdf

Left/Right are the single selections in Linsksys, diversity is both antennas at once. It's documented in the guides somewhere here on the site which port corresponds to each name.

My testing has been with an antenna and dummy load and you can indeed see a signal level decrease when you go to the dummy load antenna.

Hi All

I think most or all Ubiquity have this safeguard built into them.

-----

I just blew up my 900MHz NanoStation loco M900 by connecting it to 48 volts.  OOPS...

I removed what I believe is a Zener diode and the unit came back to life.

Thank you Ubiquity for installing this protection.

After some research I fount the replacement.

It is a Little Fuse part number SMCJ24A

It is a transient clamping sacrificial diode.

It shorts when parameters are exceeded

I just order 10 through Mouser to have in stock

Cost is about $0.50 each

Hope fully this will help some folks

Keep an eye on BBHN->ticket:43

It can't hurt, and I did do mine just out of general practice. If they are on 3.0.0rc1 I wouldn't worry that much on it in this particular case, especially if the node is hard to get to.

Literally the only change between 3.0.0rc1 and 3.0.0 is a change to the version.  This isn't to say this will always be the case on a release candidate build, just that in this case rc1 is exactly the same as the a stable release.  If it's one of the 3.0.0b builds (beta compared to release candidate) than absolutely upgrade as it wasn't until RC1 we put the last fix in to fix stability issues found in the 1.1.x builds.

I have a Ubiquitit Nanostation M5 with the XW hardware version that is currently incompatible with MESH-HAMNET firmware.  Any idea when we might see something that we can test or use?

Awesome!  So I assume I should change all of my units to the 3.0.0 production version?

3.0.0rc1 is the same as 3.0.0 which is now a stable release.

Last week we updated the firmware on some Linksys WRT54G v.2 units to 3.0.0rc1 BETA, but now I cannot find it in the firmware download area.  Can someone supply a link to it or send it to me?
