Nighthawk XR300 VPN Drop Outs
I just purchased a new Nighthawk XR300 and my Cisco VPN anyconnect client keeps on dropping in and out when connecting on DTLS protocol. If my connection randomly connects on TLSv1.2 then the connection is stable. How do i know the router is the probelm, well because 2x of my netgear routers behave the same and when I use a cheaper branded modem it works fine. I also create a new network adaptor on my Win10 machine using PPPoE to connect to my ISP direct and the connection is stable completley bypassing everything.
Can Netgear please investigate as to why VPN connections would be dropping out. I did some reasearch on this community page and it looks like I am not the only one who is having issues with Cisco Anyconnect client dropping every 5-10 minutes while using a netgear router.

- First try disabling QoS completely from the Anti-Bufferbloat menu. Also Disable SIP ALG in WAN Settings and untick Disable IGMP Proxying and see if that helps.
Ok, so I did exactly that -
QoS - set to never
Disabled SIP ALG and unticked IGMP ProxyingIt has made no difference....
I have attached a screenshot from the anyconnect client showing the protocol and cipher while connected on DTLS.
As stated this protocol and cipher works fine when bypassing my netgear routers, the only time the connection is stable is when this transport protocol on the VPN client would randomly negotiate at TLSv1.2 and a different cipher suite.
Its like the netgear rourters have instability on the DTLS protocol.
Here are just some other examples from this page, and to me looks to be an ongoing issue with netgear routers... I am a little dissapointed as my previous netgear router had it for 6 years, thinking the problem would go away bu purchasing this XR300 today and still the same issues.

Can this please be escalated within Netgear and its engineers to investigate?
