I updated a knowledge base article, that will appear on Support after the next every 6hr update period.
The reason for this issue is that wireless printers do not do webauth. On a Guest WLAN the clients are redirected before they are allowed access, even when there is no authentication on the WLAN there is a redirect that happens. Hence printers will not be able to authenticate and connect successfully.
Create a WLAN with WPA-PSK or Open type authentication, and connect the printer or other non HTTP capable guest resource.
Use a Non-Webauth WLAN on the Guest Access VLAN for non-webauth capable guest resources.
1. Create a Standard WLAN with WPA PSK,
2. Connect the printer on this WLAN.
- Most printers will work with open and WPA enabled WLAN's.
- WPA2/AES combination is prefered if the printer/device supports it.
For the above scenario, if the Guest user's are placed on a VLAN, then we can allow them to
access the printer by creating a Standard WLAN (with/without auth), tagged with the same
VLAN as the Guest user's.
After connecting the printer to this WLAN on the same VLAN, the Guest user's will be able to
access the printer/other resource.
If a customer wants Full Client Isolation enabled on the Guest WLAN, they will have to allow
the printer's IP address under Restricted Subnets (eg: 192.168.2.25/32 - this /32 host address
allows only this single IP) to permit/allow the Guests access to the device.
