ProblemDebugging steps; possible cause & solution
The wireless link is operational but the expected capacity is not met




1) Go to the Maintenance page and click the «Check Latest Release» button. If a newer firmware version is available, proceed with the firmware upgrade in order to benefit of the latest radio features and improvements
2) Go to the Maintenance page, click the «View Current License» button and check if the maximum transmit rate, power levels or channel width are limited to lower values compared to the expected configuration
3) Go to the Switch page. Check the Rate limit and the Port mode. In case of GE connection, if one unit has auto negotiation enabled and the other has a manual setting, put both units in auto negotiation.  If the rate is lower than the expected one, adjust accordingly or set to unlimited

4) Go to the:

  • Status page and check the radio link status (CINR, RSSI, etc.)
  • Radio page and check the the radio link configuration: maximum modulation, air frame period, AMC and QoS strategy (take as reference the throughput values available in Operation & Administration chapter, Wireless Link Statistics section to compare the configuration settings with the expected capacity)
  • Alliagnment page and check the values from the the antenna alliagnment tool
  • The recorded statistics should be cleared for both units ("restart the unit" or "cli> xg stat -clear") and the wireless link situation must be monitord again

Redo the radio planning activities if the values does’n correspond to the values from the initial deployment

5) Go on site and:

  • check the Ethernet or SFP connections, replace the cables if necessary
  • check the RF connectors if an external antenna is used. Tighten the connectors and check also the integrity of the antenna
  • perform proper antenna alignment on site. If after the alignment the CINR level is still low, it indicates that external interferences are present. Try to use another frequency if available or perform a spectrum scanning
6) Report the problem to InfiNet Wireless support team with the Diagnostic card (according to the information presented in Operation & Administration chapter, in Maintenace section).
