This is our first go around using Sophos Central to manage a mix of APX120 and APX320X. We wanted the consistency of using one wireless controller since the APX320X can't be managed by a Sophos Firewall. The firewall is a Sophos XGS 136.
Several times a day we receive "The gateway IP of access point "" (192.168.0.1) was unreachable since 1 minute(s)", then it self-heals. Several APs report this. This is a flat network. We brought in a new firewall (replacing SonicWALL and Ubiquiti) a couple of weeks ago. This is causing problems with TStats registering/unregistering and another LoB app.
I am close to getting out of SC and bringing the internal WAPs back into the XGS.
