SXK80 Satellites turn pink as soon as I use VLAN tagged network

Hello MrJoshW 

Thanks for jumping in

Network topology attached.  I have simplified everything to find this issue.  The layout is pretty much the same as yours.

I also created a test environment where I used a separate router with different OS installed and connected directly to Orbi router to eliminate all other devices.  Gave me the same result.

In the current setup shown, this is showing only the path for the Orbi.  Things to note are - VLAN devices connected via Orbi or anywhere else on the network all receive correct IP's etc so the "path logic" would seem correct.  Router has simple allow all rules at present.  All switches attached are smart and also have correct RSTP values.

The devices connected to the Orbi Satellites do work for a short time (1 min max) then start to fail.  I am using a simple ping test for this.  The test involves 4 terminal windows consecutively running ping tests to - 1.1.1.1, 8.8.8.8, Gateway IP, Local Printer sitting on main LAN - nothing complicated.

My last round of testing was rather interesting as per below:

Macbook Pro (Mid 2014) - Wifi connected to SXRouter - ping test successful, no dropouts, no pink satellite. PASS
ACER Laptop (2021) (WIFI6) - Wifi connected to SXRouter - ping test successful, no dropouts, no pink satellite. PASS
Both together connected at same time to SXRouter - ping test successful, no dropouts, no pink satellite. PASS

ACER Laptop (2021) (WIFI6) - Wifi connected to SXSat - ping test successful, no dropouts, no pink satellite. PASS

Macbook Pro (Mid 2014) - Wifi connected to SXSat - ping test fails, multiple dropouts, pink satellite - network fail. FAIL
Dell laptop E7250 (2015) - Wifi connected to SXSat - ping test fails, multiple dropouts, pink satellite - network fail. FAIL
Thinkpad Laptop X280 (2018) (WIFI5) - Wifi connected to SXSat - ping test fails, multiple dropouts, pink satellite - network fail. FAIL

So from this it might indicate that the router can handle older wifi standards but as soon as it connects to a satellite it fails.

The ACER laptop is the only computer with WIF6 I have.

Once the Failing devices are removed from the network it recovers - pink light turns to blue and then off.

Can reach gateway on all counts and is actually one of the ping tests.

I don't think this is a very complicated scenario and would be common with many setups.

Any light you can shed on this would be awesome.

With thanks
