Voucher issue after disconnection

Products cnMaestro
#1

Hi,

I have configured a cnMaestro on premise and configured for the Voucher access:

- create a Guest Portal

- installed a green ssl certificate on nginx

- enabled Client Login Event Logging

- create a Vochers access and two access plans (1 day and 1 year)

- es 1 day: session duration 1 day, voucher expiry 365 days, 1 voucher device limit, bind voucher to device

When I connect for the first time a device I see the splash page, I enter the voucer code and everything works fine but if I disconnect and reconnect the device after some time the notification "Access to the Network" appears on device and the splash page shows the voucher added but there aren't communication on wifi network.

How can I troubleshoot this problem ?

Thank you

Hi Assistenzasis,

Sorry for inconvinence caused. Can you please share more details to debug:-

1. CnMaestro version(Cloud or on-premises and which version)

2. Which device model and software version

3. Which client(Android or apple and which version)

If you can share the WLAN and AP group and few screenshots of guest access portal, it will be helpful to debug.

You can inbox me the configuration and screenshots please.

Thanks.

Hi,

I understand what's the problem:

- to manually authorize some device (without web interface) I have enabled the MAC Authentication Fallback in the WLAN and in Association ACL entered the MAC address of authorized device

When this option is enabled in Guest WLAN the login of Voucher is possible only once, after the device disconnect I can't associate it to the network anymore (I need to disconnect session by the Guest Access Portal and enter a new Voucher).

Disabling this option the voucher system works fine.

I think this is a bug, (cnMaestro version 2.3.2-r7), there is a method to manually authorize a device on a guest network (without using the MAC Authentication Fallback) ?

Thank you

hi,

we had issue when mac fall back authentication is used. the issue is fixed in 3.11.4.1 beta build. will ask vinod to share this beta build, you can validate and update us.

Hi,

I've installed the beta firmware:

- every time that device connect to the network I receive the notification "Access the network" so I need to open the page and I need to turn off the wifi and turn on to finally connect to internet.

After this procedure the network works fine but I need to follow this steps every time.

Hi,

so must the voucher solution with mac fallback be considered impractical ?

There are other firmware releases where these bugs have been fixed ?

This is not solved yet, problem is when guest access is enabled, vouchers are part of the guest access, i wrote about that in another topic but support didnt answer to me…
