Jay,
Thanks for all the testing/information/tips you are providing. It has helped with my setup.
I have a large garden railway, O Gauge, that I use the YD7001 as the controller. I run the Z21 protocol on the YD7001. I have not disabled the Internal WifI but I will do that.
We had an operating session the other day with 13 trains running. There were 10 operators: 3 on WLANMaus, 5 using the Z21app (3 iPhone, 2 android), 2 using WiThrottle. We had no issues.
Also my layout is deadrail with the locos controlled via Wifi using WiFiTrax WFD-60 as the central controller for the battery powered locos. This is fed DCC from the YD7001.
The points/switches are also on the WiFi network with 28 points/ switches on 4 WifTrax switch modules.
I use a TP-Link DECO a mesh system which the YD7001(LAN), WFD-60, Point controllers and all the locos are connected to. I have a spare Netgear that is hardwired to one of the DECO nodes, this is what all the users connect to. I also tested this with a Google Mesh and an old Apple Time capsule for the users.
This all works very well.
Why two levels of WiFi: well the Z21 app, WLANMaus and some WiThrottles don¡¯t cross nodes nicely on either the DECO or Google MESH. When changing to the new node, the WLANMaus need to be turned off and on again. WiThrottles need to be closed and reopened. The Z21app goes on holiday, has a few drinks, and eventually comes back to work, in its own good time. Haven¡¯t found a way of easily getting the Z21 app to recover. Meanwhile the battery powered loco continues to run along, along with rising panic levels in the user. All fixed by having a central WiFi router.
Regards
Brian
