Public Review for Can User-Level Probing Detect and Diagnose Common Home-WLAN Pathologies? Partha Kanuparthy, Constantine Dovrolis, Konstantina Papagiannaki, Srinivasan Seshan, and Peter Steenkiste This paper addresses the emerging problem of troubleshooting WiFi pathologies in home networks (where devices connect via a single access point). The paper focuses on identifying three pathologies: low signal-to-noise ratio (SNR), hidden terminals, and congestion. Previous tools have used support of lower layers to identify these pathologies and hence are tied to specific hardware. Instead, this paper relies solely on user-level probing. It proposes techniques that distinguish the three pathologies based on probe pairs between an end-host connected to the WLAN and a server connected to the access point through an Ethernet connection. The paper evaluates the techniques in small testbed. All reviewers single out the novelty and promise of user-level probing to identify WLAN pathologies making this paper a great work-in-progress report. The reviewers also point out some shortcomings of the current solution and evaluation. The need to deploy a wired computer undermines the usability of the approach, because many home networks don t have such a machine. Although the solution is mostly hardware and software agnostic, for the experiments to work the
