Channel Invalid For Radio and Low Signal for AP 7562

izzeterol — Tue, 15 Sep 2020 19:13:01 GMT

We have 7562 in our system and for radio2 i see this message “STATE : Off [channel invalid for radio]”. Also despite 10.0 dbi 2.4 antenna and 5.9 dbi 5 GHZ antenna the access points are performing bad signal distribition. When i walk away 10 meters from AP, we are losing the signal.

Hello Izzeterol,

Please answer the following:

What Country Code is the AP configured for via RF-Domain?

What channel is radio 2 mapped to?

What version of Wing firmware is the AP currently running?

If using external antenna’s, you need to add the gain for each radio via AP Profile/Interfaces/Radio/Antenna Gain

What type of deployment is this? (Virtual Controller, Wireless Controller, Stand-alone)

From the AP CLI, you can use the following commands from the privilege prompt (enable):

enable [enter]

show wireless regulatory ?
channel-info Channel information
country-code Country code to name info
device-type Device type

Based on the Country and radio 2 being Placement OUTDOOR, will dictate what channels can be used.
