Hello - I have 3 Deco units. I have a main one hardwired (cat5e) directly in to my router (with a 300Mbps connection). Then I have an 8-port switch (TP-link Gig switch) hardwired in to that main Deco, and 2 additional Deco's plugged in to the Switch.  

This all worked perfectly for about 5-6 months. Then on Monday June 12th, I started having issues. It presents itself when making conference calls (a main function of my job) while connected to the main Deco. I get choppy audio, but all my speedtests show 300Mbps up and down, like they always do.  Browsing seems ok, but sometimes I seem to need to click things 2 times (this is new). When I connect directly to the Wifi on my router, this all goes away.  However, I need the consistent speed on the Deco's like I used to have.  So I reset all 3 of the Decos and the issue still persists. 

Did any firmwear get pushed around that time?  I didn't make any changes, and the issue is obviously with the Deco units, as I have clear calls when I bypass the Deco. Any ideas?
