In this case, /service/12 is an 802.1X network that the Chromebook is associated with, and /service/15 an open network also in range.
It shows more layer 2 details on all the BSS’s that have been discovered. This command is very useful in troubleshooting 802.1X issues. LinkStatistics/6/TransmitBitrate: 52.0 MBit/s MCS 11 LinkStatistics/5/PacketTrasmitSuccesses: 34432 LinkStatistics/4/PacketTransmitFailures: 25 LinkStatistics/3/PacketReceiveSuccesses: 63919 LinkStatistics/2/LastReceiveSignalDbm: -62 LinkStatistics/1/InactiveTimeMilliseconds: 8002 LinkStatistics/0/AverageReceiveSignalDbm: -61 Hopefully, one day we’ll be able to modify this value on enterprise-managed Chromebooks through the Google Apps admin console. This command provides some good Wi-Fi stats like retries, MCS index, and also RoamThreshold, which is the SNR at which this Chromebook will attempt to roam to a new BSS. Here are some of my go-to crosh networking commands that don’t require an explanation. Most of these tools are included in the crosh shell, which you can open by typing Control-Alt-T.
The Basicsĭespite its simplicity, Chrome OS, the Linux variant that Chromebooks run, does have some useful diagnostics tools that can help troubleshoot Wi-Fi problems. If you are designing high density Wi-Fi networks for Chromebook 1:1 programs, it helps to know how to access their Wi-Fi statistics, logs, and networking tools. This knowledge is valuable for troubleshooting day-to-day Chromebook Wi-Fi issues as well. In the K-12 market Chromebooks are the most common devices used in 1:1 programs.
