Utsegn frå AirTies
17. januar 2018
As we have communicated before, AirTies engineering team has been working on identifying the root cause and developing a fix for Wi-Fi connectivity problems reported happening after an update was released by Google for Android devices in December 2017.
After days of heavy analysis, we have successfully reproduced the problem in our labs and identified the root cause of the problem. The problem was caused by Android devices transmitting enormous number of network packets over Wi-Fi after coming out of "sleep mode”. This causes wireless packet queues in Wi-Fi chips to be filled up and freeze resulting Wi-Fi chips not being able to transmit anymore and eventually all Wi-Fi devices losing connectivity.
AirTies engineering team has developed a new software patch that identifies the packet storm from any device and recovers Mesh Extenders from this state. The new software is currently being tested in our labs and in several field installations.
Once testing is completed and the new software is verified, we will be updating devices in the field with their specific customized SW versions.

Recently we have started receiving reports about internet connectivity loss of Wi-Fi devices that are connected to AirTies Mesh Extenders. The problem is new and started happening without any change on AirTies’ software. After initial investigation, we have identified that the issue started happening after a new Android version that was released in some markets on Dec 5, 2017. Various Wi-Fi connectivity problems with Android devices have been reported in online user forums and Google has noticed problems in the updated devices. With the new version of Android 8.1 release, some problems are intended to be fixed but WiFi connectivity problem is still reported to persist. Native Android devices like Pixel2 and Nexus are most frequently reported to have issues with Wi-Fi after Android 8.1 software update. Other Android phones, such as Sony XZ and OP5T, are reported to suffer from Wi-Fi connectivity issues after Android update. Other Mesh products from manufacturers like Netgear Orbi or linksys have been showing symptoms like stopping Wi-Fi, or even resetting when Android devices are connected to them. Here is a video of Bell/Sagemcom 5250 resetting itself when a Pixel 2 XL connected to it.
At AirTies, our engineering team is constantly working on identifying the root cause and implementing a fix for our Mesh extenders software that will resolve the Wi-Fi connectivity issue that is triggered by updated Android devices. As soon as we have a fix, we will be updating the software of our Wi-Fi Mesh Extenders.
