TP-Link TL-WDR7500 (Archer C7) 802.11ac Router Review

With several new Android devices coming with the latest 802.11ac Wi-Fi, I decided I should buy a new router with AC1200 class or greater and Gigabit Ethernet support, and with a budget of $100. Xiaomi Mi Wi-Fi Mini router almost matched my requirements, but unfortunately only comes with Fast Ethernet ports. TP-Link Archer C7 selling for $96 Amazon US exactly matched my budget, and outmatched my requirements being an AC1750 router with 5x Gigabit Ethernet ports, and two USB ports. Since Amazon won’t ship to my location and shipping would have gone over budget, I expected to find it locally for a slightly higher price, but it ended up selling for over $200 here, allegedly because of a lifetime guarantee. Finally, I ended up buying TP-Link TL-WDR7500, the Chinese version of Archer C7 with 6 Wi-Fi antennas instead of 3, for $94.32 including shipping on Aliexpress. I’ll take some pictures of the device, explain options to change the Chinese web …

$25 GL.iNet 6416A is an Hackable OpenWRT Router with Easy UART and GPIO Access

There are plenty of low cost routers supporting OpenWRT, but GL.iNet 6416A has several advantages compared to devices like TP-Link WR703N. Both are based on Atheros AR9931, but GL.iNet router has more memory and storage (64MB RAM + 16MB Flash vs 32MB RAM + 4MB Flash), two Ethernet ports instead of just one, and 6 GPIOs, the serial pins, and power signals (5V, 3.3V and GND) are all easily accessible via though holes or headers. Gl.iNet 6416A can be purchased for about $25 on DealExtreme or Amazon US, and it used to be listed on eBay, but is now out of stock. Gl/iNET 6416A specifications: Wi-Fi SoC – Atheros AR9331 MIPS processor @ 400 MHz System Memory – 64MB RAM Storage – 16MB Flash Connectivity – 2x 10/100 Mbit Ethernet ports, 802.11 b/g/n Wi-FI up to 150Mbps USB – 1x USB 2.0 port, 1x micro USB port for power Debugging – Serial console via UART header (GND, Tx, Rx) Expansion …

How to Use an Android TV Box as a Wi-Fi Access Point

Today, I’ve come across another potential use case for Android TV boxes with Wi-Fi and Ethernet. Let’s say you are in a room with Ethernet, but there’s no Wi-Fi signal or the signal is too weak, and want to use your smartphone to connect to the Internet via Wi-Fi. If you don’t have one of these small (openWRT) Wi-Fi router with you, but instead brought an Android mini PC, you can configure the “Portable Hotspot” function to transform it into a secure Wi-Fi access point. Assuming you’ve connect an Ethernet cable, and powered the device, first make sure Ethernet is enabled\, and Wi-Fi is disabled in the Settings menu. To click on Settings->More.. in the Wireless & Networks section, and select “Tethering & portable hotspot” or simply “Portable hotspot” depending on your firmware. In the next menu, click on Portable Wi-Fi hotspot to enabled it, then “Set up Wi-Fi Hospot” to optionally change the Network SSID and Security protocol, and …

Soap is a Touchscreen Enabled Router Supporting Gigabit Ethernet and Lots of Wireless Standards (Crowdfunding)

Soap is a strange creature, and I’m not convinced there are that many use cases for such hardware, but I find it interesting that the developers decided to pack a Freescale i.MX6 Solo/Dual or Quad SoC powered Android 4.4 tablet and a router supporting five Gigabit Etherner ports, as well as WiFI 802.11ac, Wi-0Fi 802.11 b/g/n,  Zigbee, Z-wave, Bluetooth 4.0 (BLE), Insteon RF, X10, 433Mhz, NFC, and infrared into one and only device which they call an “Intelligent Home Management Hub”.  It’s also complete with an HDMI output port so that you can use it as a media player. Let’s go through the specifications for the four version this little monster (Soap Solo, Soap Dual, Soap Quad, and Soap 8.4): SoC Soap Solo – Freescale i.MX6 Solo single ARM Cortex A9 @ 1 GHz with Vivante GC880 3D GPU Soap Dual – Freescale i.MX6 Dual dual ARM Cortex A9 @ 1 GHz with Vivante GC2000 3D GPU Soap Quad and …

802.11ah Wi-Fi (900 MHz) to Provide Low Power, Long Range Connectivity for the Internet of Things

Most devices now feature Wi-Fi modules capable of handling 802.11 b/g/n at 2.4 Ghz (and 5 GHz for dual band Wi-Fi), and newer devices and routers boast 802.11ac connectivity @ 5GHz with increased bandwidth (up to 1.2 Gbit/s in theory, maybe around 400 Mbit/s in practive), and in some case increased range with  beam-forming. But thanks to an article on EETimes, I’ve learned there’s another upcoming Wi-Fi standard called 802.11ah operating in the 900MHz range, with data rates from 150 Kbit/s with a 1 MHz band to as much as 40 Mbit/s over an 8 MHz band, lower power consumption, and a least double of the range of a typical 802.11n device,capable of covering an area of about 1 km2. The target applications are sensors networks, backhaul networks for sensor and meter, and extended range Wi-Fi, as the standard allows long range and more clients at low bitrates. This new Wi-Fi standard will compete with other sub 1GHz wireless standard …

Linux.Darlloz Worm Targets Embedded Linux Devices

Symantec has recently discovered a new Linux worm, called Linux.Darlloz, that targets Internet-enabled devices running Linux in addition to traditional computers. That means devices such as home routers, set-top boxes and security cameras could be at risk of infection, although no attacks against non-PC devices have been confirmed yet. The worm exploits an “old” PHP vulnerability, which was patched in May 2012 (PHP 5.4.3, and PHP 5.3.13), and currently only affects Intel (x86) based systems. So you’d need an embedded system powered by an Intel processor, running Linux and PHP to be at risk. Having said that, Symantec also explains code for other architectures such as ARM, PPC, and MIPS, is also present in the worm, and these systems could potentially be at risk too with small modifications. Here’s how the worm operates: Upon execution, the worm generates IP addresses randomly, accesses a specific path on the machine with well-known ID and passwords, and sends HTTP POST requests, which exploit …
