Both my wife and I have been having fairly consistent issues connecting to our separate work vpn's over my Deco M9.
I've ruled out issues with the network connection, running continuous pings on my personal laptop while both laptop connection consistently drops packets over SSLVPN. We're connecting to different providers, and using different VPN clients (FortiClient and Cisco NetExtender) and have had multiple freezes 20 or more times per day. I've also frequently had the connection on my phone freeze when connected to wifi and Nord VPN.
The VPN connection work fie when tethered to my phone, or wired direct to a router(TL-R600). After restarting the Deco, things may be fine for an hour or two, sometimes even a few days, but the dropped connection issue alway seems to come back.
Really at a loss here. It seems there's been some reported issues but no resolution on the Deco M5. Not really sure what else to try at this point.
