Cisco Cisco Aironet 1522 Lightweight Outdoor Mesh Access Point Guía Para Resolver Problemas

Typical throughput and performance are based on backhaul performance delivered to the RAP, the 
number of mesh hops, the noise and interference on the mesh wireless backhaul and on the wireless 
access side as well as client transmit uplink power. Tools such as wireless 802.11 sniffers and software 
spectrum analyzers can be used to troubleshoot local on-site issues. 

Additionally, Cisco WCS and the controller already have noise and interference feedback tools built-in 
to the controller AP monitor and WCS Report pages; in general, these tools display Pass or Fail results 
based on default criteria.

1) Lack of connectivity between the 
controller and the access points could be 
tied to either problems with network 
elements (wireless backhaul, switches, or 
routers) or because of low SNR.
