EX6100 and Google Pixel

I recently purchased a Google Pixel, and it is running completely stock Android.  The problem I have is that the Pixel will not stay connected to my EX6100 while it acts as an extender.  I have no issue enabling both the 2.4 and 5 ghz networks on the extender and having devices connect to it - in this regard, the extender is perfect.  However, the Pixel is unable to hold a connection to either 2.4 or 5 ghz on the extender.  I have tried the Pixel on other modems and it works flawlessly, so it must be that something is conflicting between the Pixel and the extender.  I have tried changing all kinds of settings on the modem to which the extender is connected to, and have tried disabling either the 2.4 or 5 ghz network to isolate a potential issue in either speed, but nothing seems to work.  I am wondering if the Pixel's software/hardware may not be 100% compatible with the EX6100.

I look forward to hearing if there are any suggested fixes or possible updates to the extender to address this.

Thank you,

Simon.
