Wi-Fi issues
When a Wi-Fi access point is connected to the same switch as an ELAN IP Amp in Multicast mode, network
routing can flood the Wi-Fi and degrade the performance of the link if the hardware and/or network settings
are not adhered to . You may be experiencing this condition if you are experiencing loss of the Wi-Fi signal .
There are two ways to resolve this issue:
Option #1: Set the network to handle the multicast traffic appropriately
.
• Temporarily power down any ELAN IP Amps and EL-IPD-PRE-SSI .
• With the network congestion removed, you can now make the network settings changes .
• Follow the correct network switch settings for Multicast use on all switches .
»
Follow the correct network switch settings for multicast use on all switches in the project .
»
After the changes have been completed, you can power on the IPD devices .
Option #2: Factory default the IPD chassis (only applicable with no EL-IPD-PRE-SSI’s set
to Multicast)
This method is used when non appropriate network gear is used and thus not able to run multicast .
• Press and hold the micro reset button (on the Dante card, or next to the Ethernet connection) until a click
is heard (~ 30 seconds) . This will reset the chassis back to factory condition .
Important:
While the chassis is rebooting and before writing down the chassis configuration, uncheck the
Multicast box .
• The chassis will need to be written to from the configurator after it comes back online to sync it with the
zone settings .
• Make any changes necessary to the network before re-enabling Multicast mode .
Common Multicast issues:
»
No/intermittent Wi-Fi
: incorrect switch setting or non-compatible hardware
»
Improper multicast network setup
: IGMP & QoS . See above for Luxul specific settings .
»
Incorrect network hardware
: To use multicast, the network must be able to handle IGMP and QoS which
is found on layer 2/3 switches .
»
Poor network infrastructure
: Poor cascading, ends, cables
Example:
An EL-IP-PRE-SSI, for example, is often connected to a small switch located behind the TV which is
not layer 2/3 . If the connected EL-IP-PRE-SSI is in Multicast mode as the switch cannot handle the traffic and
as such will cause flood the switch as well as any other devices connected to that switch . Use a layer 2/3 switch
or run another wire for the EL-IP-PRE-SSI .
Note:
For Araknas switches, the DSCP should be set up in this manner:
1 .
Set
DSCP 8
to
Queue 3
. This is for low priority “reserved” usage .
2 .
Set
DSCP 46
to
Queue 7
. This is for medium priority Audio traffic .
3 .
Set
DSCP 56
to
Queue 8
.
