Azure Percept Connection to Hotel Wifi

Question

Problem : I have an Azure Percept setup pumping out azureeye vision recognition data.
I wanted to run the system on a large hotel chain's wifi network.

Current Process :

1. Attempted to connect to their Guest wifi, but the splash screen/popup isn't accepted so that option was ruled out.
2. Hotel setup a hotspot with password.
3. I was able to connect to the new wifi hotspot with OOBE, but

• webstream not working
• Azure Percept Studio I can see the device show up as connected (green check mark), but when I select live telemetry I don't see any traffic.
• I also tried to click on view live stream and I get an error message that the system can't get an IP address.

4. The hotel IT turned off client isolation.
5. retested the next day and I could see the webstream on internal IP address, but :

• live telemetry still shows no traffic
• device shows up as connected in Percept Studio
• can't see webstream from Percept studio (no ip address), unless I enter it into browser manually.

Answer 1

Hi @CharlesElwood,

1) You are correct that the Percept cannot connect to "guest" networks that require signing in via a popup screen.

2) To view the webstream the wifi network must not be blocking port 3000

3) To view the inferencing data the wifi network must not be blocking port 8554.

It appears that when the hotel removed client isolation on the network they unblocked port 3000 but not port 8554.

Hello @Charles Elwood ,

I am not familiar with the Azure Percept but it is basically just another IoT Edge device running some kind of Linux.

Are you able to perform a 'sudo iotedge check' on the device itself? This can give some clues why it's not working.

Also, try to ping 8.8.8.8 to see if you can connect to the internet.

Try to limit the connection to MQTT over Websockets or AMQP over websockets.

Last but not least, check if you need extra proxy settings.

Yes, hotel WIFI can give a lot of issues. Personally, I always carry both a hotel WIFI converter router (a D-Link DIR-505 still works) and my mobile as a hotspot (So I have a direct internet connection).
