We would like to announce the release of a new HAL for Atheros WLAN devices. The new HAL is the result of a collaboration between OpenWrt.org, DD-WRT and MakSat Technologies (P) Ltd. It is the first result of a common effort, and the present collaborators would like to share the product of this work. It is their intention to provide reliable and continued support for other projects using this new HAL for Atheros WLAN devices.

The HAL provides a defined API to access and control Atheros WLAN chipsets, and is an integral part for many drivers such as MadWifi. Comparing it with the HAL that’s currently used by MadWifi, the most important changes are:

  • many known bugs have been fixed
  • improved noise immunity measures
  • added support for additional architectures, such as ARM11, MIPS64 and MIPS32r2
  • enhanced support for Atheros WiSOC (Wireless System on Chip)
  • added support for Atheros AR7100

Home of the new HAL will be the website of the madwifi.org project. Future development will be coordinated here, and the bug tracking facility can be used to report bugs or file feature requests.

For commercial requests please contact hal@maksat.de.

The following is a list of links to involved projects and/or already available vendor solutions using the new HAL for Atheros WLAN devices:

  • OpenWrt.org – embedded linux distribution and development environment
  • DD-WRT.com – professional and end user firmwares for common wireless routers and boards
  • Maksat Product Line – offers tough hardware and special software enhancements for all areas and very inexpensive small APs

Friday, February 29th, 2008

New interesting product is coming to market Ubiquiti NanoStation – two versions for 2.4ghz and 5ghz bands.

There is not much info available only the info and datasheets. A both devices running new Ubiquiti AirOS which is also interesting.

Ubiquiti NanoStation 2 and 5

The device designed to advance the Global Wireless ISP industry to the next level. Featuring a compact indoor/outdoor design and an interface so intuitive even the most technically challenged can instantly become experts. But, don’t be fooled; it is as powerful as it is simple. Nanostation packs some phenomenal performance with a revolutionary design combining a hi-gain 4 antenna system, advanced radio architecture, and highly researched and developed firmware technology allowing throughput, stability, and capacity performance rivaling even the highest-end WiMax networks. All at a MSRP of $79.

Resurrecting a bricked Netgear WGT624

Thursday, October 18th, 2007

Here You can find very good tutorial how to resurrect bricked Netgear router WGT264 without using a jtag cable :

http://www.embraceit.com.au/wgt624/

There are some interesting steps in this tutorial. First is the step 4 were the trendnet firmware is stripped or converted from .img format to .elf file.

“… Step 4.

The TRENDnet firmware needs to converted from its .img format to the .elf format so that the file is bootable over TFTP. I used http://www.cygwin.com and the following Linux command to strip the superfluous header information :-

dd if=510APB_1121US.img of=510APB_1121US.elf skip=52 bs=1
…”
Second interesting thing is that the author is used AP firmware to reflash router. May be will be possable to reflash a router and use different wireless modes like AP client or WDS ?
