Cisco AnyConnect VPN repeatedly fails with AC1300 Deco M5 mesh
Please note: my model wasn't available to select in this form. The model I am using is AC1300.
I use Cisco AnyConnect at work to access the VPN. Lately, the connection has become so unreliable that I can't use it any more. I have never had a problem before; I've been working from home for 2 years with no problems.
In the last couple of months, however, the VPN connection has been awful. Sometimes it works fine. Sometimes I can access public sites like Google over VPN, but I can't access our internal domains (e.g. email, Teams, and private domain names that we use for internal things). Sometimes I can't access the internet at all.
Is there a known problem with Cisco AnyConnect, and is there a solution to this issue?
