On August 29 at noon EDT, we hosted a webinar on how to monitor a WiFi network with a Raspberry Pi. The goal of this webinar was to share what we’ve learned so that you can get up to speed and either implement your own custom WiFi monitoring solution or just…
Iperf on Single-Board Computers I have done iPerf performance comparisons in the past between several well known single board computers (SBCs), which you can see here, and more recently, here. The most popular SBC is the Raspberry Pi, but its limitation is that it has a 10/100 interface, and the…
Monitoring Enterprise Networks Enterprise networks are evolving at a fast pace, and with them, so are network monitoring techniques. If you are monitoring your network with an SNMP collector, you have already realized that it’s not enough to detect and troubleshoot problems experienced by the end-users. You can read more…
What’s HORST? The Highly Optimized Radio Scanning Tool (HORST) is a lightweight IEEE802.11 WLAN analyzer. It was built for troubleshooting WLAN networks, and although it’s not as advanced as other tools (Kismet, Wireshark, tcpdump) it’s very easy to use, free, and can run very efficiently even on a Raspberry Pi….
On Thursday, February 23rd, I will present at the WirelessLAN Professional Conference on how to Turn your Odroids or Raspberry Pis into Remote WiFi Monitoring Sensors. This is part of the WLPC TEN talk series, in which presenters have ten minutes for their talks. It takes less than ten minutes…
Wireless is connecting the world 802.11 networks are not just providing connectivity to our laptops and smartphones, but are also allowing us to interact with IoT devices like refrigerators, light bulbs, and cars. When complemented with Internet access, wireless connectivity is, in the end, a utility, a service that is…
A couple of months ago I blogged about using a Raspberry Pi as home network monitoring agent. The idea was to collect data from home networks and compare the performance of different ISPs as well as detect outages and be notified about them. Guess what? There is nothing new under…
