Since 2 months we have wifi problems with 80 chromebooks C738T

Since 2 months we have wifi problems with 80 chromebooks C738T, Chromebooks spontaneously lose WiFi connection. Wifi is no longer available
when via shell prompt (ctrl + t) wifi_power_safe status, the result is: no wifi device available...
This problem occurs with different networks. At school, at home and at work.

The number of chaperebooks with these problems is increasing.

a way to temporarily fix the problem is to reset the Chromebook or to shut down for a long time. It solves the problem for 1 - 3 days.

Disconnecting the battery also sometimes helps.

Replacing the internal wifi card for a new one does not solve the problem.
It is an Intel wifi card.

We are a school with 4200 chromebooks (acer) all included in Google G-Suite administration tool.
Google Chorme OS 63.0.3239.140

Is this a known problem?

    We are experiencing same issues. We have about 10 devices with the no wifi device available. Wifi appears to be off, when wifi is turned on, its stays on for 2 seconds and automatically turns off again. We have 150 C738t devices total. Replacing the wifi card with a known working one does not work, power washing does not work, reinstalling ChromeOS does not work, disconnecting the battery for a while and reconnecting SOMETIMES solves the issue for one or two days. Restarting the device ( Refresh + Power ) random amount of times ( 5 to 15 times) also works but loses connection at the next shutdown or when lid is closed. We have 2 other manufacturer devices and only Acer seems to be affected. 

    On Chrome OS 66.0.3359.158

    Using a USB to Ethernet adapter is the only way to get them back online.

    Any fix on this?

    I just joined this forum and did it because we have exactly the same problem in our school.

    We have about 300 Acer Chromebooks of which roughly one third is model C738T-C87F. Other models have had no problems.

    Is there any solutiuon to this wifi-issue?

    Please contact your IT and have them contact our Premier Advocates to better assist with this or any issues on your Acer Chromebooks.

Our team is available Monday through Friday from 9:00 a.m. to 6:00 p.m.
