Acer Chromebooks - Intermittent WiFi

[tomgrindle]

Hi All!

 

I am currently having a problem with a suite of 30 Acer Chromebook 13 CB5-311's. They keep connecting and disconnecting from our wireless network, despite having at least 70% signal strength.

 

Our Wireless Network is Meru with multiple SSIDs setup, although we have turned these off temporarily to see if it illuminates the problem. Unfortunately it doesn't seem to have made a difference. All other devices seem to be okay, without problem.

 

Has anybody else experienced this before? They have been fine since September and have only caused a problem in the last couple of weeks, but nothing has changed ....

 

Thanks

Hi Tom

 

I think there was a Chrome update in late June. We have subsequently seen an issue on a customer network with Chromebooks.

 

We see very high levels of channel utilisation across the 5GHz spectrum when the Chromebook requests a web page. This doesn’t happen with laptops (2.4 or5GHz) or with the chromebooks at 2.4GHz (20MHz channels). We have an open support call with the WLAN vendor.

 

Might be worth restricting to 2.4Ghz only ad see how you go.

Hi @Wave9_Andy

 

Will give that a go, thank you! Have since noticed a few settings buried in the controller which looks like they have set back to default, probably down to a power cut that we had!

 

Have a new Controller going in over the summer, so that will hopefully eliminate the problem anyway, or make it worse

Did this resolve the issue?

 

Thanks,
