Hey battags,
I did some testing on my system, and I found out that even though I'm on AP mode for whatever reason it is not working perfectly.
Basically I have my old router from which the internet is coming from. This old router is emitting a WiFi (lets call it WiFi "Old"). Then I plugged the Almond+ on it through ethernet and the almond+ is emitting a WiFi too (lets call it WiFi "A+"). The Almond+ is in AP mode.
All my equipments are plugged on the Almond+ through Ethernet (NAS, Sonos, etc...).
It seems that when trying to access the equipments from the WiFi Old it does not work even though it should. Of course when connected to the WiFi A+, I've got no problem trying to access my equipments. I will test the other way around in the afternoon (equipments on the old router in ethernet and accessing it from WiFi A+).
In your case did you make sure the Bridge was connected on the same router that was emitting the WiFi on which you are trying to connect from? it might be the solution for you.
