Simple Scanner Finds the Best WiFi Signal
Saturday, 22 April 2017 07:01

Want to know which way to point your WiFi antenna to get the best signal? It’s a guessing game for most of us, but a quick build of a scanning WiFi antenna using mostly off-the-shelf components could point you in the right direction.

With saturation WiFi coverage in most places these days, optimizing your signal might seem like a pointless exercise. And indeed it seems [shawnhymel] built this more for fun than for practical reasons. Still, we can see applications where a scanning Yagi-Uda antenna would come in handy. The build started with a “WiFi divining rod” [shawnhymel] created from …read more

Intel's buggy Puma 6 chipset earns Arris a gigabit-modem lawsuit
Tuesday, 11 April 2017 10:07

Cable modem maker Arris is facing a class-action suit over its handling of a lag-prone line of cable modems.

The complaint , filed in the Northern California District Court, accuses the vendor of violating four California state consumer protection laws and seeks relief for folks in the Golden State who purchased an Arris SURFboard SB6190 modem since its launch in late 2015.

According to the complaint, Arris violated state laws on misleading advertising and unfair competition, as well as consumer protection and warranty laws, when it advertised and sold the SURFboard cable modems as "gigabit" home internet boxes.

Finally a reason not to bother with IPv6: Uh, security concerns...?
Tuesday, 11 April 2017 08:18

For all those sysadmins tired of having to make excuses for why they haven't moved to IPv6, worry no more: the new protocol brings with it the risk of network infiltration.

That's according to NATO's Cooperative Cyber Defence Centre of Excellence, which has published a research paper [PDF] claiming it is possible to set up undetectable communications channels across networks that could be used to pull out data and control systems remotely.

There's only one downside for IPv6 laggards: the security holes come as a result of IPv4 to IPv6 transition tools.

"Tunnel-based IPv6 transition mechanisms could allow the setup

DIY DynDNS with ESP8266 and Dweets
Thursday, 13 April 2017 07:01

You’re on a home router, and your IP address keeps changing. Instead of paying a little bit extra for a static IP address (and becoming a grownup member of the Internet) there are many services that let you push your current IP out to the rest of the world dynamically. But most of them involve paying money or spending time reading advertisements. Who has either money or time?!

[Alberto Ricci Bitti] cobbled together a few free services and an ESP8266 module to make a device that occasionally pushes its external IP address out to a web-based “dweet” service. The skinny: …read more

ESP32 WiFi Hits 10km with a Little Help
Wednesday, 12 April 2017 04:01

[Jeija] was playing with some ESP32s and in true hacker fashion, he wondered how far he could pull them apart and still get data flowing. His video answer to that question covers the Friis equation and has a lot of good examples of using the equation, decibels, and even a practical example that covers about 10km. You can see the video below.

Of course, to get that kind of range you need a directional antenna. To avoid violating regulations that control transmit power, he’s using the antenna on the receiving end. That also means he had to hack the ESP32 …read more

US cops, firefighters to get new emergency wireless network – AT T to get $6.5bn
Friday, 31 March 2017 06:08

US phone giant AT&T has landed a $6.5bn contract to build a private wireless broadband network for emergency responders.

The FirstNet system will be a nationwide network that will allow police, firefighters and paramedics to transmit data and communications across multiple regions and jurisdictions without worrying about the transmissions being lost to overcrowded networks, particularly during disasters.

The network, running in a 20MHz band in the D-Block spectrum space , will initially operate as a private LTE (Long-Term Evolution) system that includes wireless data and radio access network (RAN) voice transmissions. The FirstNet system will cover all 50 US states
