Troubleshooting
Problem Solution
Wireless Interface • Performance and Stability Issues
Validation
- Check the distance between two co-locating devices. The distance between
two co-locating devices should be minimum 3 meters, in order to achieve good
throughput and maintain link stability. The operating channels should maintain
5MHz spacing if managed by a single administrator.
- When DDRS is disabled, check the Minimum Required SNR for the current
data rate by navigating to MONITOR --> WORP Statistics --> Interface 1
--> Link Statistics Page --> Click here for Local SNR-Table. If the current
SNR is not meeting the minimum required SNR criteria for the current data rate,
then accordingly reduce the data rate.
- If SNR is more than the maximum optimal SNR limit (MONITOR --> WORP
Statistics --> Interface 1 --> Link Statistics Page --> Click here for Local
SNR-Table) then it causes radio receiver saturation thus impacting the
performance of the link. To overcome this situation, set the TPC appropriately
or enable ATPC to adjust the signal level automatically. Also, enabling DDRS
can help in choosing right data rate automatically.
8.9 Recovery Procedures
8.9.1 Soft Reset to Factory Defaults
Use this procedure to reset the network configuration values, including the Password, IP Address, and Subnet Mask. This
procedure resets configuration settings, but does not change the current device Image.
To use this procedure, in the web interface navigate to MANAGEMENT > Reset to Factory.
The device gets the default IP address (169.254.128.132). You can change the IP address using Web Interface or CLI. If you do not
have access to the HTTP or CLI interfaces, use Hard Reset to Factory Defaults procedure.
8.9.2 Hard Reset to Factory Defaults
If you cannot access the device or you have lost its password, you can reset the device to its factory default settings by using the
Reload button available on the PoE injector. With Reload, the configuration settings are deleted from the device and the device
reboots, using a factory default configuration.
:
• Please note that if the PoE supplied with the Product Package is not equipped with the Reload functionality then
you will have to use a PoE which is equipped with the Reload functionality to reset the device to its factory defaults.
• You need to use a pin or the end of a paperclip to press the Reload button.
: If you hold the Reload button for longer than 10 seconds, the device may go into Forced Reload mode, which erases the
device embedded software. This software must be reloaded through an ethernet connection with access to a TFTP
Server. See Forced Reload for instructions.
