This article describes basic troubleshooting actions to be taken in case a problem occurs to the wireless link.
List of possible problems:
|
Step 1: Local unit check
Check the network connectivity between the monitoring server and the local unit. If no connectivity appear, go on site to the local unit location. Check if it is powered on, power indicator has blue color, wired connection: red – 10 Mbps, yellow – 100 Mbps, green – 1000 Mbps. If there is no power please check the AC power supply, the Ethernet cables and connector. Check if the local connection works by using a laptop or ERConsole.
If the local connection is allowed, after the authentication step in web interface, check the operational status of the wired port. Enable the port if found disabled, check the connectivity matrix and VLAN settings if used. Reboot the unit at the "Maintenance" section.
Step 2: Report the problem to the Infinet Wireless support team
If you are unable to identify the cause of the problem, please contact the Infinet Wireless support team. It is necessary to provide diagnostic card, antenna alignment test results screenshots, the installation points photos, the installation points coordinates.
The section describes how to test the link when there are no radio communication and no access to the remote unit, but there is access to the local unit.

Step 1: Check the weather conditions
The 70.5-76 GHz frequency range is sensible to the weather condition changes, rain, snow and fog can significantly affect the wireless connection quality.
Step 2: Local unit check
Check if the radio parameters values of the local unit correspond to the settings from the radio planning stage:
If some parameters have different values, perform the modifications and check the wireless link establishment after unit reboot. In case the wireless link is still down, go on site to the location of the local unit and check the cables and connectors.
Step 3: Remote unit check
In case the wireless link is down even if the parameters were set according with the radio planning results, go on site to the location of the remote unit. Check if it is powered on, power indicator has blue color, wired connection: red – 10 Mbps, yellow – 100 Mbps, green – 1000 Mbps. If there is no power please check the AC power supply, the Ethernet cables and connector. Check if the local connection works by using a laptop or ERConsole.
If the local connection is allowed, after the authentication step in web interface, check all radio parameters by connecting to it using a laptop. The values for the following radio parameters must be the same on both units:
Step 4: Path profile check
If the wireless link is down after previous steps, check the antennas alliagnment with two teams working simultaneously, one at the remote side and the other one at the local side. Also, redo the radio planning to avoid the situation when coordinates at the initial radio planning stage is different from the current location: huge interferences on the working set of frequencies, Fresnel zone obstruction are possible reasons why the wireless link cannot be established, etc.
Step 5: Report the problem to the Infinet Wireless support team
If you are unable to identify the cause of the problem, please contact the Infinet Wireless support team. It is necessary to provide diagnostic card, antenna alignment test results screenshots, the installation points photos, the installation points coordinates.
The wireless link is established but the capacity is less than expected.

Step 1: Check the weather conditions
The 70.5-76 GHz frequency range is sensible to the weather condition changes, rain, snow and fog can significantly affect the wireless connection quality.
Step 2: Local and remote units settings check
Login to both units via web interface, check the availability of the new firmware version. If a newer firmware version is available, proceed with the firmware upgrade in order to benefit of the latest radio features and improvements.
In the "Dashboard" section check the EVM and RSSI parameters values:
Proceed to the "Radio" section and check the frame length value, if it is too small, try to increase it. Perform the antenna alignment with built-in tool especially in case of low RSSI and EVM values.
To view parameter values changes over time, use the "Graphs" tool by clicking the diagram icon next to the selected parameter, or by going to the "Graphs" section.
Step 3: Check at the units location site
Further actions should be done on the site of units location. Check the Ethernet connection, as well as the cables integrity. Tighten the connector and check the antennas, as well. Perform proper antenna alignment on site. If after the alignment the EVM level is still low, it indicates the presence of external interference. Try to use another frequency if available or perform a spectrum scanning.
Step 4: Report the problem to the Infinet Wireless support team
If you are unable to identify the cause of the problem, please contact the Infinet Wireless support team. It is necessary to provide diagnostic card, antenna alignment test results screenshots, the installation points photos, the installation points coordinates.
The wireless link is established but no data is being transffered.
Step 1: Local and remote units settings check
Connect to the unit web interface and check the matrix connectivity in the "Switch" section, ge0 port must be connected with the radio port.
|
Check the operation status of the ge0 port. Enable the port if it was disabled. In case of using VLANs, proceed to the "Switch" section and make sure that the VLAN configuration is correct, the specific traffic VLAN ID is allowed to pass through the port.
|
If the port status is "Up" but no packets are received, check the configuration of the equipment which is directly connected.
|
Step 2: Check at the units location site
Further actions should be done on the site of the units location. Check the wired connector, as well as the integrity of the cables.
Step 3: Report the problem to the Infinet Wireless support team
If you are unable to identify the cause of the problem, please contact the Infinet Wireless support team. It is necessary to provide diagnostic card, antenna alignment test results screenshots, the installation points photos, the installation points coordinates.
If the management of the unit is completely lost (of the local and/or the remote one), the ERConsole recovery procedure should be used. ERConsole is a software application created to recover or add a new IP address to the Infinet Wireless units. Additionally, the ERConsole can be used to reset the Infinet Wireless units to the factory default configuration.
Software requirements::
It is recommended to turn off any anti-virus or firewall running on your computer and to turn off all the network interfaces, except the Ethernet interface connected to the same broadcast subnet as the Infinet Wireless unit. If no device can be discovered by ERConsole, turn on the firewall, and add an UDP connection port 10009 as an exception.
We also recommend to use a simple unmanaged switch as intermediary unit between your PC and the Infinet Wireless unit. It is essential to reboot the Infinet Wireless unit each time in order to activate the Emergency Repair Protocol on the unit, therefore the switch would prevent your PC Ethernet interface from flapping up and down. Using Cisco Catalyst switches for unit recoverty is not recommended due to a known issue port mode negotiation delay.
IP address should be configured on the PC for the ERConsole utility work.
|
ERConsole and Infinet Wireless units exchange information only during the bootup process, therefore each time you need to read the units IP address, to add a new IP or to restore to the default configuration, the Infinet Wireless unit should be rebooted. |
If you have lost management to your unit, proceed as follows:
|
Further recovery depends on whether the IP-address is assigned or not to the unit.
IP address and net mask are assigned
Configure on your PC an IP belonging to the same network and connect to the unit in order to perform the modifications and checking required. If there is no IP, displayed (0.0.0.0), proceed with the next step.
IP address and net mask are not assigned
In the "New task" window, set the additional IP address and network mask, then click "OK".
|
In case you need to restore your unit to the factory default settings, proceed as follows.
If the management of the unit is lost due to unknown user name or password it can be restored using factory password. Enter the device serial number to the "Login" field and factory password - to the "Password" field. |
Select "Reset configuration" option and enter the factory password to the "Factory password" field, then click "OK". The password must be entered at the same format as it has been got from the distributor or IW support team (with the gaps).
