Hi Hank,

When I start a new measurement, in addition to the standard measurements
like ping and traceroute, I see a "wifi" measurement that appears for
about 2 seconds at the end of the list and then auto-disappears.  See
attached screenshot. 

Explanations?

The plan to introduce wifi measuements was first communicated with the community in November 2015. See the RIPE Labs article here:
https://labs.ripe.net/Members/suzanne_taylor_muzzin/ripe-atlas-wifi-measurements

An update to our plans was published in January 2016:
https://labs.ripe.net/Members/suzanne_taylor_muzzin/ripe-atlas-wifi-measurements-part-2

As outlined in the article, steady work has been done on the WiFi feature and it's been made available to some users in our production environment as a Beta feature.

The latest update can be found in Kaveh Ranjbar's Technical Services Report over 2017:

As for the user interface issue, users who cannot create WiFi measurements should not see the WiFi measurement option. So you should not be seeing that option at all.

I have discussed this with one of our front-end developers and this will be fixed in the near future.

Kind regards,

Thanks,
Hank
