WPA2 Key Reinstallation Vulnerabilities (KRACK) Explained
Posted by Hemant Chaskar on Oct 16, 2017

Researchers from the University of Leuven (@vanhoefm and team) have discovered flaws in WPA2 implementation in clients and APs. These flaws create vulnerabilities for replay and decryption attacks on packets transferred over WiFi links. They have named them KRACKs (Key Reinstallation AttaCKs). Both 802.1x (EAP) and PSK (password) based networks are affected. These vulnerabilities have been cataloged under 10 CVEs. In the series of videos below, I explain these CVEs in detail with Vivek Ramachandran, Founder and CEO of Pentester Academy.

Meraki MR53 MR42 benchmark performance test
Benchmark: The 4x4 Meraki MR53 vs. the 4x4 Mojo C-120
Posted by Robert Ferruolo (Dr. RF) on Sep 8, 2016

In a recent blog post we compared the performance of the Mojo C-120 to the Meraki MR42. In that blog we highlighted results of a test we ran last spring. When we test, we test the best of the competition with the latest software and published best practices at that point in time. When that test was run, the MR42 was the best Meraki had to offer. Once Meraki made the MR53 available, we tested it and here are the results.

Mojo Networks provides a great K-12 solution by covering the three S’s for education – Safety, Simplicity, and Savings. We provide safety with the best WIPS solution in the industry. Our cloud managed WiFi stretches E-Rate dollars, saving the unnecessary cost of controllers, and our pricing eliminates expensive AP markup. Our automatic AP configuration couldn’t be simpler. I’d like to add a fourth S to this line-up: Speed.

HD Video Streams: How Many Can Your AP Support?
Posted by Robert Ferruolo (Dr. RF) on Aug 30, 2016

The classroom paradigm continues to shift as new technology is adopted. Long gone are the days of watching a movie in class by threading the film from one reel, through the projector, onto the other reel. Film was replaced by videotape, which was replaced by laser disks and then by DVDs. The new classroom instruction model includes HD video streamed wirelessly on demand from a local/regional distribution server (or from the web) to each student, who has their own computer or tablet.

The latest paradigm is much more personal and interactive, which greatly increases the number of clients (tablets, laptops, and smartphones), the client density, the different types of applications, and the requirements and bandwidth those applications. In order to be able to support this shift, many parts of the school’s IT infrastructure must be updated, especially the wireless LAN.
