I have my node set up. It's a Ubiquiti Nanostation in a window of my 14th floor apartment in downtown LA (facing east). Unfortunately it doesn't see any node but my other one (a linksys with improved antennas). On the upside I was able to connect through my two nodes at about 9 miles. Going to play around with my raspberry pi 2 and netbook linux server and see what services I can come up with for the node.

Hoping to connect sometime,

Anne

Just wanted to check and see if anyone in Austin had a Linksys Router for sale before I purchase one on ebay.

New User. KF5ZHJ. I'm in South Austin, hoping I can get linked up soon :)

Thanks,

It looks like the FCC noticed their comments, and are addressing them:

Does anyone know where to get heat sinks for Linksys routers?

I am slowly replacing Linksys with 'Ubi' gear. I would like to use the Wrt54gl for another purpose, does anyone know how I might format it, re-flash it with DD-WRT? Ive tried uploading but the current hamnet firmware wont allow it. Ive also tried uploading Linksys firmware in a two step process to getting DD WRT on there, but no joy.

Any ideas on how I could format the router or remove the hamnet firmware from it?

Any help appreciated. 

Thanks 73

Hi, I tried the suggestion, It appears that the new firmware is loading, it reboots, but it keeps coming back to the LUci interface, the ip address is still the static 192.168.1.1, the router seems to work though, which in itself is a positive, just not BBHN ... 73

p.s.  I have a serial console installed using putty to monitor

KTF, All,

OpenWRT based 802.11 adhoc mode usage that we are running OLSR on top of in BBHN is only 802.11a and max possibility is 54Mbps of raw protocol bits back and forth. One would have to go to 802.11n modes to obtain the 40Mhz channels or MIMO dual spacial streams to be able to achieve a higher rate. OpenWRT (that BBHN is on top of) only has these rates implemented in 802.11 AP mode (not used by MESH) for atheros ath9k chipsets in Ubiquiti hardware.

Here's an example of the rate control algorithm under OpenWRT (Barrier Breaker newer version) of the rates in use from a live node. This node is finding 5.5Mbps as the optimal rate to use. Note max of 54Mbps. This is a NSM2.

Depending on the hardware, band, bandwidth, clear line of sight and clear Fresnel zones, I dont see why you couldnt get up to 100MB/s or better.

If your Fresnel is a bit obstructed or SNR is a bit low, you can lower your bandwidth to get a better signal at the cost of speed.

Hello All!,

I am just wondering what kind of speeds I could expect to see on a BBHN Intranet network.

If I had, say, two nodes on the roof of two very tall buildings that were about 30 miles away from each other but were just about line of site from each other when you were on the roof, what data speeds could I expect to see between the two nodes?

If it already has OpenWRT loaded, use the TRX file at the top.

BIN files are for when it is still in stock Linksys firmware.

Hello all, recently I aquired a WRT54GS V2 router. The router has the firmware OpenWrt Barrier Breaker 14.07 / LuCI installed on it, but I thought I would upgrade it to the latest BBHM firmware.  This router has the LUCI interface with the details as follows:

Firmware Version OpenWrt Barrier Breaker 14.07 / LuCI Trunk (0.12+svn-r10530)
Kernel Version    3.10.49

So I tried to upgrade the firmware to BBHN using the web interface:

Flash new firmware image
Upload a sysupgrade-compatible image here to replace the running firmware.
Check "Keep settings" to retain the current configuration (requires an OpenWrt
compatible firmware image).

Using this .bin file  bbhn-3.1.0-wrt54gs-2.4-squashfs.bin

but it was not successful with this message.

The uploaded image file does not contain a supported format.
Make sure that you choose the generic image format for your platform.

Further reading on  http://wiki.openwrt.org/toh/linksys/wrt54g

states

Using LuCI

1. Select Administration in the top right corner
2. Choose the System > Flash Firmware tab
3. Click Browse and navigate to the firmware (it must be a .trx file) you wish to flash to
4. Click 'Upload image'

So, am I able to use the trx file listed on the site, it however states that it is for an upgrade to an existing mesh node.

Any thoughts would be appreciated..thanks
