I've always got problems with my network speed on my XE75 mesh with 3 access points, but the only meter of health is the wifi connections.  Everything should be fine, all connections are as good as I can see with the wifi symbols, the internet is easily fast enough but my video chats are always lagging, and I can't easily check my internal network speed?  Dogshit.  Any other options seeing as this app is never going to support it until I can get a new mesh system to replace this hunk of sh!t.
