Constant internet drop out, speed test failing
Model is brand new Deco M4R (it won't let me enter model number in field above!).
Constant internet drop out via BOTH wifi and Ethernet connection to modem from both apple and windows devices.
Connected to ISP via PPOE with custom VLAN setting per ISP configuration.
Have done factory reboot, and having bought 3 M4s for a mesh, have changed the device that is the master, done factory reset and configured same way with same symptoms.
When I remove and put my old modem back in (a TPLink VX220) the issue disappears so it is not being caused by my ISP.
Have latest firmware version it will let me download.
Running speedtest.net it constantly (regardless of server I choose, or which device I connect with) after showing high speeds for a few seconds stops with the error
" DOWNLOAD TEST ERROR. A socket error occurred during the download test. A firewall could be blocking the connection or the server might be having some issues. Please try again later. "
Browsing, streaming etc is near impossible due to constant disconnect.
Again, if I plug my old router back in this problem is not there.
I have been through the configuration of the device twice with my ISP on the phone to make sure I am not doing anything silly.
It's going back to Amazon tomorrow if I can't fix it!
