5.3.4.6.1 WAN Backhaul Deployment Considerations
WAN Backhaul Configuration
Before defining a profile's WAN Backhaul configuration refer to the following deployment guidelines to ensure these
configuration are optimally effective:
• If the WAN card does not connect after a few minutes after a no shutdown, check the access point's syslog for a
detected ttyUSB0 No such file event. If this event has occurred, linux didn't detect the card. Re-seat the card.
• If the WAN card has difficulty connecting to an ISP (syslog shows that it retries LCP ConfReq for a long time), ensure
the SIM card is still valid and is plugged in correctly.
• If a modem doesn't responding with an OK during the dialing sequence, the WAN card is in an unknown state and will
not accept a command. Re-seat the card and begin the dialup sequence again until the card is recognized.
• If encountering a panic when conducting a hotplug, power off the access point for one minute. The access point could
continue to panic or detect the descriptor of the last utilized WAN card. Thus, it's a good idea to clear the panic state
by temporarily disconnecting then re-applying access point power.
• If wanting to unplug the WAN card, ensure sure you shutdown first, as the probability of getting a panic is reduced.
With the new high-speed WAN cards currently being utilized, the chances of getting a panic significantly increase.
Provide your password for authentication support by the cellular data carrier.
Enter the name of the cellular data provider if necessary. This setting is needed
in areas with multiple cellular data providers using the same protocols such as
Europe, the middle east and Asia.
Use the drop-down menu to specify authentication type used by the cellular
data provider. Supported authentication options include None, PAP, CHAP,
MSCHAP, and MSCHAP-v2.
