Point to Point signal question

[ Edited ]

My question is really just trying to make sure i am understanding the information i have.  Here is the background:

i have a Point to Point mesh going about 60-80 feet accross the street.  It is using an AP92 on each side. The Client side has a switch connected to the AP providing network to the building which consists of a few offices with 4-5 workstations and a few IP phones(hardwired).  We are running software version 6.1.3.0

Users have been complaining recently of poor network performance and had a few issues with their phones loosing connection.  Introubleshooting this i went the the VRD for a point to point and made sure i had good settings for things. I am now looking to see if we are having a signal problems.  Airwave reports the following, hopefully this is not formatted to poorly and it will help)

AP Name Ascending Device Address Link Time Duration Link Type Local Radio Index Remote Radio Index SNR Signal RSSI Transmit Rate Receive Rate

It looks like the channel its on has alot of interference/noise.  Am i reading that right?  If that is the case why does ARM not switch it to a different channel to try and get less noise?

Re: Point to Point signal question

What are your ARM profile settings and Radio profile settings for the APs involved in this link ?

An update to this.  I create a whole new profile from scratch for the mesh. I followed the VRD for a Point to Point Mesh for the whole thing.    I have been experimenting with 2 spare AP's and even when they are in the same room i cannot seem to get them to better signal strength then -65dbm.   ARM is disabled.  Here is the Radio profile settings for the A radio(g is disabled).  Let me know if there is anything else i can provide. Left is B/G and the right column is A

Re: Point to Point signal question

This should be a relatively simple setup and should work.  

 

Please attach a "show tech-support" from the controller.

 

What antenna type do you have on each side?
