“OpenWRT vs. FCC – Forced Firmware Lockdown?” Video and Presentation Slides

The article about the new FCC rules that may prevent installing OpenWRT, DD-WRT or other third party firmware on Wi-Fi routers and access-point generated quite a buzz at the end of the last month. The “OpenWRT vs. FCC – Forced firmware lockdown?” presentation that started that discussion took place yesterday during BattleMesh V8 event, and the video has now been uploaded to YouTube. Sound quality could be better, and the slides are not shown on the video, but you can download the PDF slides to have an easier time following the presentation. Some keys points include: The requirement to lock firmware are likely to affect all users, not only those living in countries following the FCC regulations. Not only WiFI access points would be affected, but also phones, tablets with CyanogenMod, and more. Vendors will have to “describe in detail how the device is protected from “flashing” and the installation […]

New FCC Rules May Prevent Installing OpenWRT on WiFi Routers

Many cheap WiFi routers are sold with the vendor firmware, but the most popular ones likely also support OpenWRT, which some users may prefer as it is much more customizable. However, this may soon become more difficult according to a talk at the upcoming “Wireless Battle of the Mesh” which will take place on August 3-8 in Maribor, Slovenia. The talk scheduled for August 6 at 15:00 is entitled “openWRT vs. FCC – forced firmware lockdown?” and Simon Wunderlich, the speaker, provided the following abstract: The new FCC rules are in effect in the United States from June 2nd 2015 for WiFi devices such as Access Points. They require to have the firmware locked down so End-Users can’t operate with non-compliant parameters (channels/frequencies, transmit power, DFS, …). In response, WiFi access point vendors start to lock down firmwares to prevent custom firmwares (such as OpenWRT) to be installed, using code […]

Linux Based Zsun WiFi Card Reader Has Been Hacked Too…

A little while ago, I purchased Zsun SD111 W-Fi USB flash drive, and after several tentatives, I finally found a way to access the device’s serial console. Since then the company announced another wireless storage device with Zsun Wi-Fi card reader, and Zoobab decided to try to hack it too. Since the device is pretty hard to open without damaging the enclosure, connecting the serial pin was not really an option, and the first exploit was to input shell commands in the web interface SSID field… For example, entering reboot there, would indeed reboot the device. However, this would still not allow full shell access, and finally after a broader port scan, it was found out that TCP port 11880 was open for telnet daemon. You can then access the shell as root with the same password as SD111: “zsun1188”. For some reasons, telnet can’t work with the device, and […]

Olimex Announces RT5350F-OLinuXino and Evaluation Boards Availability

Olimex had been working on a small board with Ralink RT5350F processor for over a year, with delays mostly due to software development and undocumented registers. But RT5350F-OlinuXino is now available together with an evaluation board with tow relays, two Ethernet ports, and expansions headers, as well as a DIN EBV still in development. RT5350F-OlinuXino specifications: SoC – Ralink / Mediatek RT5350F MIPS24KEc CPU @ 360 MHz System Memory – 32MB SDRAM Storage – 8MB SPI NAND Flash 3x headers with access to USB 2.0 HOST/Device 5x 10/100 Mbps Ethernet port GPIOs, SPI, I2C I2S, PCM UART JTAG Power – 3x external DCDC power converters releasing internal RT5350F vreg and preventing common problem with overheating with this chip. Dimensions – N/A Operating Temperature Range – -10 to +55C The board is pre-loaded OpenWRT with Linux 3.18.11. You can find builds instructions and other documentation in the Wiki, as well as […]

FireWRT is an OpenWRT 802.11ac Board Powered by Mediatek MT7621A Processor

There are plenty of low cost 802.11n routers or boards supporting OpenWRT, even starting at $10 or less such as A5-V11 mini router, but if you’re looking for something a bit more powerful with 802.11ac connectivity, options are much more limited, especially if you need something at a lower cost. One option is Xiaomi MiWiFi router based on Mediatek MT7620A with 64MB RAM, and T-Firefly team is now working on FireWRT board based on the more powerful MT7621A processor coupled with 512 MB RAM, and 16 MB SPI flash. FireWRT specifications: Wi-Fi SoC – Mediatek MT7621A dual core MIPS 1004Kc processor @ 880MHz System Memory – 512 MB DDR3 (Beta version: 256 MB) Storage – 16 MB SPI flash memory, 2x SATA 3.0 ports, micro SD card slot Wi-Fi 802.11 b/g/n @ 2.4GHz up to 300Mbps 802.11 a/n/ac @ 5 GHz, up to 867Mbps (AC1200 class router) External High-Gain Antennas […]

RaidSonic Releases Firmware and Source Code for Atheros AR9331 Wi-Fi Audio Streamers

RaidSonic is a German company releasing products such as media players and multimedia accessories under their ICY BOX brand. One of those products is ICY Box IB-MP401Air music streaming received based on Atheros AR9331, and that looks very similar to SoundMate M2 I reviewed last year. But if you look on their product page, you’ll find out a few download links: ICY BOX IB-MP401Air  (multilang) – The Quick Start Guide and User’s manual in English and German IB-MP401Air (Source code) – a 648 MB rar file with source code for U-boot and OpenWRT IB-MP401Air (Firmware) – The firmware IB-MP401Air (Open Source Software) – Just the open source licenses So I’ve downloaded the source code file (IB-MP401Air_Sources_and%20License_Terms.rar) to have a look. It has two compressed files, one with the license, and IB-MP401Air_Sources.tar.gz with the source code.

The file showing how to build the firmware (OpenWRT) explains you should not use […]
