System

I have a single XE200 unit operating as a router connected to an NBN modem (HFC).  (Formerly operated as a two-unit system, but the second is currently disabled).

Per ISP requirements: Connection is via PPPoE. IPv4. DNS is auto-acquired. IPTV/VLAN enabled with custom profile, internet VLAN ID 2 and priority 0.

Devices typically connected to the network are a PC (via ethernet) plus iPhone, security camera system, and various other IoT devices (via wifi).  When operating these devices, I have a stable internet connection.

Issue

When I connect a work-issued laptop to the wifi network, the following occurs:

1. I will retain an internet connection on all devices, and internet will be available on the laptop for about 2 minutes.

2. Immediately after that, I will loose the internet connection on all devices.

3. The internet connection will not reestablish by itself.  To regain an internet connection, I must disconnect the laptop from the wifi network and do a power off and on of the XE200 and NBN modem.

4. This achieves a stable internet connection for the non-laptop devices on the network, but the laptop cannot be reconnected to the wifi network without the internet dropping out again.

ISP and NBN advise there are no network issues. NBN modem has been replaced and network wiring checked and replaced as necessary. 

Have tested with two different XE200 units with the same result.

Error log

The following is an example of an attempt to connect the laptop to the wifi network, and an internet drop at around 14:17.  The loss of IP and DNS is at 14:17:34.

Request

Any guidance on what's causing this issue and how to resolve it would be much appreciated (including so that I can pass it on to my work IT team, if necessary).

Many thanks,
