Bridges Wireless - AP 1310

[alrbatista]

Hi,

I'm setting up a Wireless Bridge 1310 with two APs. The Root Bridge is working fine, but the Non-root Bridge is not working, the radio 0 is not UP (It is in reset mode), bellow the settings of APs and logs Non-root Bridge.

Thanks.

No response in the logs could possibly indicate nonroot is not hearing the root.

What is the distance between the two bridges? Are they in line-of-sight to each other? Try to put them next. To each other and try. Make sure the preshared key is the same on both.

Hi Amjad,

The distance is 500 meters.

Yes, are one in front of another.

The key is the same.

The APs are on top of two towers, we will remove the APs and the test on the ground.

Thanks.

Make sure to double checlk the cables connecting the Antennas to your Bridges if you have -R version of the 1310 bridges.

Your issue is very simple , non-root cannot detect the presence of the root ( no 802.11 frames advertising the same configured SSID ) --> Accordingly keeps scanning indefintely on all the channels of a certain band.

When selecting the channel on root make sure that it is clean as well on the non-root side to allow the non-root to connect properly wihtout having the info sent by root distorted due to noise , interference or any other RF impairments on certain channel. So you can run the carrier busy test many times on both sites and select the clarest channel to proceed with after making sure that everything else such LOS, HW status ......etc is ok.
